Some people continuously worry about getting cancer. In fact, a population-based survey found that although a third of respondents never worried about getting cancer, more than half worried occasionally and 6% worried often.[1]

When the persistent fear of cancer rises to the level of an overt phobia it is known as cancer phobia or carcinophobia. It may lead to repeated medical examinations that fail to reveal a malignancy. Despite this, people with this condition are unable to be reassured about their clean bill of health for any length of time. This article will explore why most of us probably don’t need to worry about getting cancer.

Luckily, as the survey demonstrated, most of us are not overtly phobic about cancer, even though it may be lurking deep in our subconscious. Why is it not an active fear for the bulk of the population? It is likely because in people without any signs of cancer, it is not perceived as an imminent threat. We are hard-wired to fear clear and present dangers. Risks and threats far into the future don’t get as much priority in our constellation of daily fears.

Examples of this from our daily life abound. For example, research has demonstrated that most people are not willing to take urgent action on climate change if it is presented as a distant threat.[2] But if portrayed as proximal in time and place, more people are willing to act with urgency.

This may seem unrelated to worrying about cancer, but the underlying neurobiological mechanism is the same. We’ll explore that later in this post.

So, should we worry more about getting cancer?

George Klein (1925-2016) was Professor Emeritus at the Microbiology and Tumor Biology Center at the Karolinska Institute in Stockholm, Sweden when he published a fascinating article in The Scientist. The article makes the point that approximately one in three people will be struck by cancer in their lifetime.[3] But, the other side of that coin is that two out of three people remain unaffected. Even the majority of heavy smokers who bombard their lungs with carcinogens and tumor promoters over many years remain cancer-free.

A systematic review revealed that prostate cancer’s incidental findings at autopsy ranged from <5% in men under age 30 to almost 60% by age 70.[4] A not-insignificant percentage of these cancers, when localized and low risk, do not progress to overt cancer during the person’s lifetime. This has led to a recommendation option of active surveillance as opposed to treatment.[5]

It is also known that circulating tumor cells (CTCs) are present in many cancer patients. However, only a portion of these cells will enter and persist in distant parts of the body.[6] These are known as disseminated tumor cells or DTCs. An only a fraction of them develop into secondary tumors (metastases).

  • What keeps these micro-cancers in check?

They are kept in check by a mix of the following elements:

In other words, when it comes to getting or not getting cancer, the glass is more than half-full.

So, should we just relax and not worry? Actually, that’s not a productive question to ask. A more interesting one, that may actually produce interesting answers is:

What makes most people resistant to cancer?

What causes cancer?

As the Cancer Society of Finland succinctly states [9]:

“Cancer is caused by accumulated damage to genes. Such changes may be due to chance or to exposure to a cancer causing substance.” 

Risks related to developing cancer

There are a number of ways this damage can occur including, but not limited to this list:

      • Lifestyle factors that expose us to carcinogens, including
        • tobacco smoke
        • alcohol
        • UV radiation in sunlight
        • food factors, such as nitrites
      • Occupational exposures, such as  
        • asbestos
        • tar and pitch
        • polynuclear hydrocarbons
        • some metal compounds
        • certain plastic compounds
      • Infections with certain viruses or bacteria (Helicobacter pylori, hepatitis B, or Epstein-Barr)
      • Radiation exposure
      • Some drugs, in particular,
        • medications that weaken the immune system
        • anticancer drugs
        • certain hormones
      • Genetic predisposition (for example, Lynch Syndrome [10])
      • Factors not yet identified

We know that colon cancer, breast cancer, and prostate cancer, develop through progressive stages of mutations that ultimately cause cell division to spin out of control and proliferate wildly.

Is cancer resistance simply the absence of mutations?

You might be wondering at this point if not getting cancer is merely the absence of harmful mutations? If that were the case, then is not getting cancer simply a matter of luck? To answer this question, let me paraphrase Albert Einstein’s quip about quantum mechanics, evolution doesn’t play dice. It increases its odds with natural selection.

It turns out that mutations, harmful or otherwise, occur all the time in all of us. With a few exceptions related to certain genetic or pathological conditions, most of the rest of us possess several well-known anti-cancer mechanisms.

The body’s anti-cancer mechanisms

In a classic paper published in PNAS, George Klein identified five kinds of anti-cancer mechanisms [11]:

1. Immunologic

The first type of resistance Klein describes is immunological. For example, researchers have compared the antibody responses of the squirrel monkey and the marmoset when infected with Herpesvirus saimiri. Marmosets, but not the squirrel monkeys, develop rapidly growing lymphomas after exposure to the virus. Of note, the virus is endogenous to squirrel monkeys, but marmosets never encounter it. 

The researchers found a striking difference in the timing of each animal’s antibody response. In the tumor-resistant squirrel monkeys, the antibodies rose to a high level just three days after the infection. However, in the marmosets, the response took three weeks, too late to stop the virus-driven lymphoma.

The dynamics of the antibody response suggest that squirrel monkeys had pre-existing memory T cells against the virus. Whereas the marmosets had to develop them first before a full-blown antibody response could be mounted, a process that takes about three weeks.

2. Genetic

The second mechanism Klein describes is genetic. Our cells are constantly subjected to DNA damage. And, there are individual variations in the efficiency of the repair mechanisms.

Although, in the vast majority, these mechanisms are capable of repairing the damage quickly, some are not. An example is a DNA repair deficiency disorder called xeroderma pigmentosum [12]. Individuals with this deficiency are highly sensitive to ultraviolet light. Even with careful protection, they develop multiple skin cancers due to their genetic deficiency.

3. Epigenetic

According to a review of cancer epigenetics, the term refers to the “study of heritable changes in gene expression without alterations in DNA sequences.” [13] Unlike changes in the genome itself, epigenetic changes are reversible. Some key epigenetic processes include the following:

        • changes in DNA methylation,
        • chromatin modifications,
        • alterations of nucleosome positioning
        • changes in non-coding RNA profiles.

These alterations can lead to altered gene function as well as a neoplastic transformation of cells.

The next two mechanisms are, for some reason, my favorites.

4. Apoptosis or cell death

As part of an intracellular defense, a cell can trigger apoptosis (cell death) if it detects extensive DNA damage. This prevents the cell from reproducing and spreading the damage. It is the ultimate altruism on the cellular level.

In some individuals, this mechanism fails. For example, The cellular protein P53 is a tumor suppressor. When it is mutated, it increases the risk of inheriting Li-Fraumeni syndrome [14], a rare disease in which patients develop multiple cancers starting from childhood.

5. Factors in the tissue’s microenvironment

The last mechanism of defense against tumors resides in the microenvironment in which tissues are embedded. Here is a striking example. The naked mole-rat (NMR) and the blind mole rat (BMR), live up to 20 and 30 years, respectively, and never develop cancer. How do they pull off this trick?

The naked mole rat

The naked mole-rat (NMR) displays exceptional longevity, with a maximum lifespan exceeding 30 years [15]. This is the longest reported lifespan for a rodent species. It is especially striking considering its small body mass. In comparison, a similarly sized house mouse has a maximum lifespan of 4 years. In addition to their longevity, naked mole-rats show an unusual resistance to cancer.

The NMR is a social species that live in highly organized matriarchal societies. It has to force its way through narrow and often sinuous underground tunnels. The connective tissue in its skin contains a high-molecular-weight form of hyaluronic acid (HA) that makes the animal’s skin malleable. The corresponding HA in mice and humans has less than one-fifth of the molecular weight.

The heavy form of HA that occurs in the NMR is not only beneficial for the animal’s locomotion. It also prevents the transformation of normal cells in cell culture into cancer cells. Only after it has been removed can the NMR’s cells be transformed into cancer cells. The NMR cells also display an extreme sensitivity to contact inhibition. The cells stop dividing when barely touching each other.

The blind mole rat

Several species of the blind mole rats (Spalax judaei and Spalax golani) are common in Israel and surrounding countries. BMRs are small subterranean rodents. They are distinguished by their adaptations to life underground, remarkable longevity (with a maximum documented lifespan of 21 years. They also show remarkable resistance to cancer.

In tissue culture, when overproliferation starts taking place after several cell divisions, BMR cells began secreting interferon ß. [16] This triggers a massive cell suicide response (a.k.a. apoptosis). The Masada phenomenon is apparently alive and well in this Middle Eastern species.

In case you conclude that it is subterranean living or the small size that protects these animals from getting cancer, think again—the blue whale is cancer-resistant as well.  So, we don’t have to live underground or go back to the ocean where our very distant ancestors came from.

The bottom line is that most of us don’t need to worry about getting cancer

Rather, we can take a deep breath and relax because two-thirds of us will never develop cancer for all of the reasons described in this article.

As for the other third, don’t despair. New diagnostics and therapeutics for cancer are being developed at a rapid rate. That doesn’t mean all cancers are curable yet. But I, for one, am putting my faith in human ingenuity to one day make cancer much less feared than it is today.

  1. This was a good article. I freak out over the C word.. every pain, bump or bruise and my mind goes straight there. Medicine is big $$ so dont trust them so im into preventative as much as possible.. though i respect their place as needed. Most know nothing about nutrition and supplements (i like to think more are waking up to this) but Big Pharmas running the show.. dont mean to offend but we all know it..
    I wish all great health! :)

  2. I think this site is AWFUL
    don’t worry u wont get cancer how TACTLESS
    I have a gr8 Auntie with breast cancer who died @ 53, & 2 sisters in their 50’s who have it & i have to go for a follow up
    If people didn’t get cancer they wouldn’t bother having mammograms

    • Dear Wendy,
      A careful reading of this post will show that 2/3 of people will never develop cancer in their lifetimes. However we feel about the subject, these are the numbers. It will also show that among the factors that should raise concern is genetic predisposition. You obviously belong to this group. Furthermore, this article, and physicians in general, never advocate not following the recommendations of the American Cancer Society and the CDC with respect to mammograms and other cancer-prevention tests, such as colonoscopy, PAP smears, etc. But this is a far cry from the person who is constantly worried about having cancer, sometimes to an extreme degree of emotional iterative loop precipitating anxiety attacks.

  3. I had fear of getting colon cancer for 3 years I am 23 and every day I actually believed I had it.

    Now I am okay I was a hypochondriac but have a doubt
    Now that I have thought so much about it will it happen to me in the future (like the law of attraction)

  4. Hi everyone, I’m 20 and I constantly fear about cancer specifically esophagus and stomach cancer because I had h pylori (since eradicated) and stomach problems and pains and I feel nauseous and weak every morning all day nothings working when it comes to medication they just say it’s probably acid reflux when I go to the ER but none of it does anything for me. I’m currently waiting to see a GI but this is controlling my life. I can’t work, I lay in bed most of the day depressed and with anxiety attacks (it’s come to the point where it’s all that on my mind all day) fearing for my health and that I’m going to have cancer and die and I won’t be able to have a life with my girlfriend and I just don’t know what to do. I just need some peace of mind:( any input would be appreciated

    • Hi Victor,

      You are not alone. My situation is very similar to yours. I tried to lose weight the past few months by restricting my calories intake. I did lose a lot of weight but gut problems arise – stomach pain after meals, constipation (sometimes), acid reflux. I too went to endoscope and the doctor said my digestive system is completely fine. Nonetheless, whenever I feel a slight sense of pain/discomfort, fear and anxiety strikes. I had a polyp when I was young as well but no family history of cancer. I am 30 years old.

      Would appreciate some input from the author as well!

  5. I ran across this article after yet another google search on cancer. It seems every few months or less, I experience something that spirals into my fear of having cancer. My fear has caused rifts at times in my marriage, and has made me feel so guilty about the possibility that my three year old daughter will see me panicking and it will affect her. I can’t seem to get my obsessive thoughts of dying from cancer out of my mind. Right now it’s over back pain and flute pain, I even had an MRI done. Hopeful the results will show it’s nothing. Even writing this I picture myself looking back only to find out I have cancer. I know I need help and I have been in therapy for months now. But every new symptom gets that fear back. The article seemed to help, it’s said the more knowledge you know, typically helps to separate irrational and improbable things to what is more likely to be true. I plan to continue to try and overcome my cancer phobia and live a healthy and happy life. Thank you for addressing the facts to those of us that do fear cancer.

    • Hi Jennifer,
      You are not alone. There are literally thousands of completely healthy people seized by a mortal fear of cancer. It can totally paralyze you, not unlike other anxiety attacks. You are doing the right thing seeking therapy. However, the fact that you’ve been months in therapy tells me you may be getting the wrong kind. The only mode of therapy that was demonstrated to be effective is called CBT, which stands for Cognitive Behavioral Therapy. rather than delve into the past to find the psychological roots of your problem (which they rarely succeed), CBT concentrates on the here and now and ways to cope with the problem at hand. I would recommend trying it.

      • Thank you so much for the reply. I am trying mindfulness techniques, but the presence of any pain or illness makes it very hard to get a grip of what is real and stop living in a movie where I’ll be diagnosed with cancer. I’m so glad to read that it’s not as likely as I imagine it to be. But my overall goal to is to handle any situation I’m dealt with, with a positive mindset and not so doom and gloom. Once again thank you for the read.

  6. Thank you for this… I’m 18 and lost two family members (father and grandfather) to the same type of cancer (it’s genetic). Thankfully, the gene is recessive and I only have one of them. I’m still constantly on edge though. It’s motivating me to eat healthier, but I’ve recently been nervous every moment of the day. I’m scared of drinking out of plastic bottles, eating meat, microwaving things, etc.

    I hope that I’ll be able to quell my fears.

    • I worry constantly as well after losing my mom to colon cancer. It’s such an overwhelming fear. I’m
      Sorry you’re struggling with it.

  7. Hi Dov Michaeli, Thank you for your response. It it naturally comforting to have you comment directly to my intial Comment.

    I am unfortunately allowing this fear of this disease to control my life, I am looking into seeking professional Help. I legit am that worried about it, it is affecting me mentally, emotional and personal life. I know i shouldnt and it probably is very offence to people who are actually dealing with Cancer in their everyday life i just can not help the thoughts i have and the What ifs……. I think in all honesty social Media and the news have a lot to answer for when it comes to creating fear in the minds of people regarding this or any sort of disease.

    Again thank you for your response, Thank you for your understanding……. I think i will from now on take the approach in life to just enjoy what it has to offer no matter is thrown my way. Health Anxiety SUCKS.

  8. I have a fear of cancer and put off getting a mammogram. My last one was at age 38 and I finally scheduled one at 69. A spot was found on my right breast and an ultrasound was performed the next week. Thank God it was only a simple cyst so I will definitely get screening again next year.

  9. Im 16, and I am convinced I am going to get cancer at 18, survive it, then at 24 or 25, i get cancer again and battle it for 8 or 9 years and then die from it. That is what I think my life is going to be.

  10. The past couple months have been the worst. I have two bumps on the back of my neck, and I’m not sure if it’s my spine or what! I can’t get the thought out of my head that I have cancer and I’m going to die from it and there’s no way of knowing. My parents say I’m crazy. at this point I’m just losing my mind.

  11. Hello. Sorry for bothering and for my English. I’m from Romania. I dont really know if I am ‘cancerophobic’. For the last 3 months I had some swollen lymph nodes on the left submandibulary part of the neck. One of them had shrinked, but it didn’t dissapear. I’ve made some analyzes (not so many because of the coronavirus), and it says that I do have Toxoplasmosis and I had an infection with Epstein-barr some months ago. The doctor is … I think…. busy these days and he does not answer to my calls because I want to know if the lymph nodes are swollen because of toxoplasmosis or EBV (with IgG, IgA etc). I have read some articles about how EBV infections may lead to lymphomas such as Hodgkin’s or Burkitt and these months of quarantine and even now I am feeling very anxious and I am afraid that I will develop Cancer from this EBV infection. Some doctors said that i should do a biopsy to be sure that they are not cancerous but i cannot do a biopsy now because of the coronavirus. I want an opinion, how probably is to develop Cancer because of the EBV infection? Thank you for reading this. (I am a Male, 18 years old)

    • Hello, Cristian, my name is Liliana, and I am also originally from Romania. I relate to your story and I would like to tell you that I personally applaud you for not doing a biopsy. And I know that my comment is probably going to get a lot criticism, but I want you to know that, after multiple years of research and personal experiences with different ailments (I am also a formerly trained Registered Nurse) I now know that our bodies always react in some ways when something goes wrong; but if you know that and also that we have an innate ability of healing and knowing how to support it, will always bring you great results! So, don;t be afraid of cancer, first off, just pay attention at what your body is telling you and take all the steps that will result in natural healing, and these are always very simple: rest enough, stay hydrated, spend time outdoors, exercise and eat healthy! And learn how to manage stress! I’ve had some of your problems and I can tell you that Mononucleosis (Epstein Barr infection) goes away after a while if you do all of those simple steps I mentioned (the virus will stay in your body, but the symptoms will go away after a few weeks to a few months). There are plenty of books on the market in our days and I strongly advice you to start reading about Alternative Therapies; one great book you could start with is Hrana Vie by Ernst Gunter and then you can expand from there. Also, if you want to complete a natural treatment that could absolutely reset your entire health (including revitalize your immunity) I recommend that you go to Favisan (or get in touch electronically) and do one of their detoxifying programs. I’ve done that in the past and I can tell you that I was blown away of the positive results I received (you do have to make the effort of following the protocol 100% for best results).
      I wish you best of health!

  12. I constantly worry about getting cancer, or my partner or my children.. I worry everyday constantly checking for lumps and bumps and then freaking myself out thinking it could be. No one in my family has died from cancer that I know off but I know of a few people who have it or had it and are now in remission.

    I find my biggest help with overcoming this fear that seems to plague my life some days is excerise. But even then I still find myself worry about it. This article I read almost once a month and helps calm my anxiety about it all so thank you

    The statistics scare me as well 1 in 7 women will get breast cancer? Does that mean that when I walk down the street that one in 7 that I see will have it?

    • Ayla, This must be really distressing. What you are describing is a classical case of cancerophobia. I am glad this article gives a measure of relief, however temporary. To increase your level of comfort, you don’t have to worry about 1 in 7 women on the street having breast cancer. This figure is over a lifetime, so on any particular day, the number is orders of magnitude smaller. In your situation statistics can help only that much. Any phobia, including cancerophobia, requires psychological help. You should not let it control your life.

  13. A family member of mine was taking the ranitidine that was pulled off the market for high levels of carcinogen. She is paralyzed with fear. Is there any way I can help her?

  14. Thank you for the rather optimistic outlook of how you mentioned that you have faith that human ingenuity will prevail over the fear of cancer someday. My grandfather recently was diagnosed with skin cancer and I was surprised at how many treatment options were presented to us. It’s great that it was detected in its early stages.

    • Hello,
      I thought I’d share a comment as, although I’m late to the discussion, this article helped me a little and I thought I’d say thanks. I’ve had a phobia of cancer for as long as I can remember. It’s had a huge negative on my life: I suffer from panic attacks, anxiety and depression as a result of it and even though I’ve had therapy and take antidepressants, the fear is still there under the surface, waiting to strike. I started college in September, hoping to complete a degree in architecture. However, a few weeks ago, I found a lump. I’ve been to the doctor, who thinks it’s an enlarged lymph node and has done blood tests which have come back fine, and prescribed antibiotics to treat a nearby hair follicle which may be causing an infection. If not, it will be further investigated. Of course, I’m absolutely convinced that this time, my fears are valid and I have lymphoma. I’m considering dropping out of college as right now, I’m terrified my days are numbered and there’s no point even trying to realise my ambitions. I know that by writing this down, I’m contributing nothing to this article but I’ve not mentioned this episode to anyone as I don’t like to talk to family and friends about my fears as they think it’s so bizarre that I, being an otherwise rational person, could be so anxious about my health that it interferes with my life in such a big way. There’s no history of cancer in my family but I know from doing so much Googling that cancers such as Hodgkin’s are not caused by genetics and often affect young people. I guess I just wanted to get this off my chest, say thanks for an informative article and share my “struggle” with others who may be in the same boat.

      • Hi Kassandra, it is not uncommon to be worried when a doctor tells you that you need some tests to “investigate” something. But remember, enlarged lymph nodes are very common and are usually due to infection or some other kind of inflammation. Since your infection is being treated with antibiotics, the node should gradually decrease in size.

        Please don’t drop out of college because of this. And maybe refrain from googling more about lymphoma.

        I developed a rare eye disease a few years ago and spent much time googling all the things it could be. I even self-diagnosed, picking one of the many possibilities that I found. Of course, even though I am a doctor (but not an ophthalmologist) I was completely wrong.

        Diversion is always a good thing to allay anxiety. That is what they made Netflix and YouTube for.

        Let us know what you learn.

        Best, Pat

  15. Interesting take on cancer. Sure, as per 2019 reports cancer deaths have diminished by nearly 25%. Yet, cancer still remains the #2 killer globally. This is largely due to decreased rates of cigarette smoking and advances in early detection and treatment. While a 1 in 3 chance of developing cancer in your lifetime does seems low, consider in the US, drivers have a 1 in 100 lifetime risk of dying in a car related accident. Significantly lower risk! Should I not wear my seat belt? I think not. While I appreciate that patients should not spend useless energy worrying about what may happen I would not encourage people to shun preventative cancer screenings that exist for cervical, breast and colon cancer. Prostate cancer screening? That’s another story.

    • Dear Dr.Cloud,
      I agree with your comment that people should not expend useless energy on worrying about cancer. The low mortality rate in car crashes is because we wear seat belts, so not wearing them would bring the death rate to what it used to be before it was mandated by law. Likewise, we could bring down mortality rate due to lung, head and neck, and bladder cancers by the simple measure of stopping smoking. At no point did I advocate not doing preventive tests. But what you probably know, there are cancer-phobic people whose lives are consumed with fear. These are the people the article is aimed at.

      • I’m amazed and blessed to run across this. Sometimes I feel like I’m the only one that has a constant fear of having cancer at times it’s debilitating. My father passed away with colon cancer and I got a colonoscopy about 7 yrs ago and I had 3 polyps removed all benign. I can’t get myself to get another colonoscopy. The first one was so traumatic for me mostly in my head my blood pressure was high and my heart rate the doctor almost decided not to do it. I can’t talk myself into doing another one but not only do I worry about that I worry about all cancers and any slight pain or discomfort I think I have cancer and it wipes me out.

    • How about you f**k off Dr cloud? All the medical field wants is patients money and they partly do that by spreading about of false scary shit on the internet to make us always go get a check-up and spend money.. you know how I know? Because I was one of those people but I got to talk to multiple doctors about my worry’s and they all told me I should stop worrying and half of cancers are familial and half are mainly preventable for the most part. Keep in mind multiple doctors have told me that. So for anyone seeing this don’t believe everything you see on the internet, this man who posted this article is telling the truth from what I’ve heard from multiple doctors I’ve seen in the past couple months.

  16. Hi! I’m a teenage girl (14, almost 15) and I suffer from anxiety. I constantly think about this, and any time a lump or bump appears anywhere on my body, I become terrified and can’t stop thinking about it. The lumps usually go away on their own, but it’s still terrifying to think about what will happen if they don’t. For this reason, I’m also terrified of the doctor. Thank you for writing this!

  17. Hi! Great article. Is it okay if I use the photo of the worried woman for a post on my blog? Who should I give credit to?

  18. My sister got a rare sarcoma in her 30’s (leiomyosarcoma) and died from it and I know quite a few people who died from breast cancer, lung cancer, etc. So I am worried about it. I can’t help it.

  20. I know I am late to the party but I just wanted to say; that was a very positive and insightful outlook into quite a feared topic. Thank you Dr Michaeli.

  21. Whew! Human life is complex, beautiful and mysterious. Thanks to scientists and doctors laboring in their studies, trying to understand and provide solutions to our problems.

  22. Great and thoughtful post. Many of us will do ourselves more harm than good by “worrying” about cancer and getting overscreened. In the Nebraska state wellness program, the sponsors bragged about screening employees for cancer much more than the ACA “minimums,” without understanding that the “minimums” are optimums, balancing the potential harms and benefits of screens. Increasingly, the US Preventive Services Task Force is recommending fewer screens, not more.

    • Thank you for the kind comment. It will take sustained voices, like yours, to change the American midset that ‘more is better’. We should indeed promote the concept of ‘optimum’.
