Did Stress Cause My Cancer?
Does stress weaken the immune system allowing the cancer to grow? It’s a widespread belief – but how accurate is it?
The question of the link between stress and cancer has been investigated by researchers exploring whether people who experienced extreme stress were more likely to develop cancer. Many large studies of cancer and stress were done in Denmark, one of which looked at the incidence of cancer in 11,380 parents whose children had cancer. It found that the incidence of cancer among the parents was no higher than members of the general population. Another study looked at the cancer rate among 21,062 parents who had lost a child. There was no increase in cancer among the parents for up to 18 years afterward. Similarly, studies have shown no convincing evidence of rates of recurrence in women who have suffered a loss in the months and years after cancer treatment has ended.
Most scientific studies have found that stress does not increase the risk of cancer. One study had even found that high stress levels can actually reduce the risk of breast cancer, by lowering oestrogen levels. And even in the event that stress and cancer are linked, the effects would be very small compared to other factors such as lifestyle, age or family history ~ Cancer Research UK
Nevertheless, despite studies which show no evidence of an association between stressful events and a diagnosis of cancer, the perception remains among many patients that stress was a factor in causing their cancer. I am sure that many of us can look back at the time of our own diagnosis and point to a stressful situation at that time. Maybe it was a divorce, a relationship break up, the death or illness of a loved one or stress at work. We desperately try to figure out what caused these rogue cancer cells to multiply in our bodies and cause cancer. Is it the case that we need to find something to blame for our cancer?
Perhaps we could look at it another way. Many people who are chronically stressed turn to unhealthy ways of coping – smoking, drinking or eating excessively. We know these are risk factors for developing cancer, so perhaps this is our indirect link.
A quick detour at this point to the prevailing notion that maintaining a positive outlook or a fighting spirit will help you “beat” cancer.
There is no conclusive evidence that people who are distressed by their cancer experience have poorer clinical outcomes than those who feel “positive” – provided they follow evidence-based advice on treatment and care…The perception that some patients did not survive because they were not as positive as others is unfounded and unfair. Dealing with a cancer diagnosis is tough enough; being pressured into thinking that the only way through it is to remain positive and thus minimise your stress can add to a patient’s individual burden. ~ Ian Olver, Clinical Professor of Oncology at Cancer Council Australia
So, I am declaring next week on Journeying Beyond Breast Cancer, stress week or rather beat stress week. I would love you to join me in taking a closer look at the nature of stress, what your stress triggers are, and some of the ways that you have found helpful in reducing stress in your lives.
Do you believe stress had a part to play in your cancer diagnosis? Do you worry that stress could cause a recurrence of cancer or a progression of the disease?

Excellent post Marie! I’s incredibly hard to pinpoint one culprit in “causing” cancer when so many factors are inter-related. There is no fool proof way to prevent cancer- just known factors to lessen the likelihood of getting it – including lowering your stress which can lead to the aforementioned by products of anxiety and depression which can lead to…an so on and so on.
Looking forward to reading responses 🙂

Thanks for putting the spotlight on an important subject!
There’s no denying that stress causes physical changes in your body…cortisol, metabolism, heart rate, and on, that have long-term health effects.
How we deal with “stress” and what we do to counter it, is the key. A person who experiences the death of a loved one and is healthy in body, mind, and spirit will be affected differently by that life event than someone who is unhealthy.
An extremely interesting book is “When the Body Says No: Exploring the Stress-Disease Connection” by Gabor Mate, MD. Dr Gabor Mate is a respected expert in the field of psychoneuroimmunology (the mind-body influence on your immune system). He has a lot to say on the influence of stress on cancer.
While it is not healthy or even reasonable to think that the “stress” of one life event was THE cause of your cancer, in my case I definitely think it was ONE of the straws on ol’ Humpy’s back, as I had no plan to deal with the stress in my life. I thought I was dealing with it by ignoring it, but that is the worst thing you can do.
We can’t avoid stress, but we can all learn to handle it, process it in a healthy way, and use a healthy lifestyle to act as a shield. Regular exercise, and meditation are two of the most powerful ways to combat the negative effects of stress.
Maintaining a positive outlook may or may not help you live longer, but you will definitely live better, and I believe that’s what this whole life thing is about anyway, isn’t it?

Instictively I think that stress does play a part in my health. As you show, it’s very hard to prove, but having had breast cancer and changing jobs thinking it was the stress of the job that caused it, and changing to a more stressful job and getting a recurrence, made me feel that stress played a role.
No matter what is going on in our lives, again instinctively I feel that trying to keep tye stress out is better for me. Whether it had anything to do with my breast cancer or breast cncer recurrence, I can’t prove it did or didn’t, but I can choose to reduce stress as much as possible and enjoy my life and what’s around me more.

Great topic, Marie!! Looking forward to the next week. Since I was young & very healthy, with pretty much no risk factors, everyone wanted to figure out why. 2 years before diagnosis, I was run down by a taxi, resulting in a spinal injury. Lot’s of therapy & eventual surgery (successful – yay!) made for a very stressful couple of years. Most people assumed the stress of the accident caused my cancer. Only problem is that the timing didn’t make sense. For my tumors to have grown to their size & spread, the cells certainly would have existed long before the accident. Did the stress cause them to multiply faster? Who knows, possibly. It’s a convenient bad guy to focus on, but I don’t think it’s ever that simple. Cells really can take a lot of assaults before they turn rogue. As tempting as it is, I don’t think it’s very possible to point to one thing as the cause. And when people do try to pin it on one thing, they usually forget to figure in adequate time for the cells to replicate.
It’s not like I’m a huge fan of stress, though. Less stress, or just figuring out ways of managing it better are always good. It definitely impacts our lives, just not sure I can make the leap to saying it causes cancer.

Longterm stress might be one of the the long chain of dominoes that includes poor diet, alcohol, lack of sleep and no exercise. In my case, I was BRCA2+, so it was a slam dunk I would get breast cancer. This week I blogged about one of the stem cell studies funded by Stand Up to Cancer (SU2C). Stem cells are few, but they can survive chemo and radiation and come back to fight another day, so we should add the stem cell domino to our list.
If stress can cause recurrence, you and I have had way more than our share since our breast cancer diagnosis. My family physician believes the stress connection and constantly worries about me. I don’t know, so we’ll just have to see how it plays out.

It seems this is another example of trying to blame something. Saying stress causes cancer seems way too simplistic. Cancer is a complex disease. Our lives are complex. Even stress is complex. Saying stress causes cancer is almost like saying breathing causes cancer (sometimes it does) because it’s simply not possible to live a stress free life any more than it’s possible to not breathe. Having said that, stress is definitely one of the many components affecting our day to day well-being and therefore stress does impact our health. Just how much, who knows? It’s probably different for each individual. Great question. Thanks for asking it.

Wonderful post Marie! I think it’s important to tease out two issues:
Living with stress has all kinds of implications on our physical health. I do believe that stress-reduction improves our health. I also think the days of trying to find A CAUSE for cancer need to end. There are a host of factors that colude and I highly doubt we will every tease them out, though I suspect stress is one of them. And blaming the patient…don’t EVEN get me started!
Just as importantly, though, is the role that stress plays in the quality of our life. Days are sweeter and living is better when we can do so at peace. We’ll never eliminate all the stress in our lives, but focusing on the quality of our moments improves our life no matter what.
Since my mets diagnosis I’ve been working with a hypnotherapist on stress reduction and focusing on being “present”/the quality of the time I share with friends and family (or whatever else I’m doing). While I do believe it positively impacts my immune system, it’s also a better way for me to live.

In my case, I had eaten well for years, walked three to five miles a day, had babies when I was young, nursed three of them, had no history of breast cancer in my family, and was no more stressed than my peers. I got breast cancer, anyway. Perhaps there is enough stress in anyone’s life to be able to look back and pinpoint it as a possible cause.
I agree that we should live as healthful and serene lives as we can. Hard as it is not to, there is no point in stressing about things until they happen. I used to worry about everything and then my six-year-old son walked out of a locked cabin in the middle of the night and was lost in rugged mountain territory for a number of hours until the sheriff and his posse found him. I had not even thought to worry about that possibility.

What a good question, Marie. I agree that cancer, stress – in fact, life itself – is a complex issue. Like Susan, I thought the onset of breast cancer was, in part, caused by the stress of a job I hated – and when I was re-diagnosed, following another stressful period of work, I did wonder whether someone was trying to tell me something!
Personally, I find it useful to look for causes – although perhaps not a singular cause. If we had no ideas about what might cause cancer, then we wouldn’t have any of the treatments, both traditional and complementary, that undoubtedly help in one way or another.
Trying to stay positive, if you’re not naturally inclined that way, is just another stressor, and I do believe we need to reduce the number of things that stress us out. We may not be able to live in a bubble, protected from every possible cause of stress, but we can choose to spend more time in an environment that enriches our lives.
I’m looking forward to reading the continuing discussion about stress over the coming week.

Here’s my question: Does stress cause a hot flash, or a hot flash cause stress? Either way, they tend to go hand in hand. As for cancer, I feel it’s rather the same. If you weren’t stressed before diagnosis you certainly will be afterward. In my case, there’s really no clear explanation as to why cancer was allowed to grow in my body. It’s frustrating, VERY frustrating . . . but since there’s no way to know, I instead just focus on being well here and now, and find peace in how I feel today.

So, I try to eat right, exercise, etc. etc., but, in the end, I know I can’t guarantee anything. As for stress, I don’t believe it caused my cancer or might cause a future cancer. I’m much more concerned about the asbestos in my mother’s house as I was growing up and the toxins all around me today. But I try not to stress about it!

Stress is such a sticky topic! I don’t know anyone who doesn’t live under the ‘stress umbrella’ in today’s world. Which means we should ALL have cancer. (And maybe we all do and just don’t know it.) But did stress cause MY cancer? No. I think cancer is much more complicated than that.
I wrote about this topic back in April (“It’s Not My Fault That I Got Cancer”) during the WEGO Health Challenge: “As a cancer patient, I’m way ahead of you in the games of denial, shame and blame. I hitched a ride on that highway the minute I got ‘the call.’ But I relearned an important lesson that is grounded in what I have always believed: that every woman, every man, every child is born into this world with a pot and a recipe. The pot is porous, the recipe inherited. Many of the ingredients are not generic, they’re genetic.”
And I believe we’ve only scratched the surface on genetic mutations.

When I was diagnosed, my oncologist made a point of asking me about my current and past stress, including childhood issues and trauma. I have since then worked on resolving such issues. I also attended a two day seminar on the topic of stress, trauma and cancer and was fascinated with the depth of it. Brilliant folks like RG Hamer and Lawrence LeShan have done amazing research and studies on this topic and were very convincing. So yes, I do believe that stress plays an important role in cancer…the development, recurrence and progression. However, I would like to say that I don’t think this is the same thing as “being positive”…I think that term gets confused with affirmation of survival; having the confidence (valid or not) that one will survive as opposed to having a positive attitude, which implies we are happy with our cancer. It brings in the question of self-fulfilling prophesy ….I will survive or I will not. Doctors have been known to tell people they have three months to live…and the patients dies three months later….after all, doc said they will die, so they resign themselves to this opinion. Often you hear of those who question that prognosis, and many are alive and well years and years later. Such an affirmation is not a guarantee of survival, far from it, but I think it helps to provide us with the strength to be proactive in our treatment, our care and our health. But I digress…yes, I do think stress played a role in my cancer; but it was far from the only culprit.

Hi Marie, Lori and everyone else.
Clearly this is a discussion-worthy topic.
The thing is – if weak papers are presented by the press as “evidence” that stress causes breast cancer, then many primary care docs, journalists and others (including women with BC) may think it’s true. Physicians are more likely to ask about it, and do studies on it, and then women tend to think about it and wonder and mention it more. So just talking about the subject can affect the results of a correlative study on behavior. To be clear, I’m not saying that stress can’t factor into a woman’s well-being and outcome. But there is no evidence whatsoever that stress “causes” breast cancer. It doesn’t. I will write more on this.
Thanks again, Marie, for raising the issue.

Great topic, Marie! I like my oncologist very much – he is very compassionate while also being a stickler for evidence-based practice. This has its limitations, as there’s so much we don’t have evidence about as yet and sometimes I wish that he’d give me more of his ‘gut feeling’ about things – but at the same time I appreciate the way that he always draws careful distinctions between what is and isn’t proven. I also appreciate his willingness to answer emails! A while after finishing active treatment I sent him a message asking about stress – focusing on its impact (if any) on recurrence risk, rather than as a cause of the original cancer. My pre-cancer life had – like most people’s – been rather stressful. My profession (social work) can be a stressful one – but I also find it very rewarding. Like countless other women I combine (or rather, ATTEMPT to combine!) my job with a myriad of household/kid-management duties – as well as some other activities (like a busy choir, keeping up with friends, a book club etc) that bring me pleasure. In the wake of cancer treatment I felt an urge to do MORE rather than less (I dubbed this ‘Carpe Diem Syndrome’), but was simultaneously very anxious that failure to reduce stress levels might make me more vulnerable to recurrence. When I put this to my oncologist, his pithy reply was (and I quote): “The effect of stress is totally unknown. Stressful life is usually normal life, and that is just as important.” I really liked this answer, and took from it that returning to what for me was ‘normal’ life (as far as this was possible) was a good thing, even if this involved a level of stress. I have certainly had periods in my life (in particular jobs, for example), when I felt that my stress levels were unhealthy. I think there’s a dividing line between energising, cramming-stuff-into-life stress and overwhelming, think-I’m-getting-an-ulcer stress. I’m keen to embrace the former without ever again letting it veer towards the latter! And, for me, learning to manage ‘fear of recurrence’ stress is a work in progress. It can become quite a messy mind-game, worrying about recurrence and then worrying that WORRYING might make it more likely! Quite a yucky snowballing effect. I’m interested in exploring meditation as a means for coping with cancer-related stress and anxiety – but have been too busy to do this yet!!! (Suspect there’s a lesson in there for me – and that I’ve got a way to go in figuring out how to deal with this issue….!).
Sorry for rambling – am up far too late (ahem). On second thoughts, don’t listen to anything I say about stress (and if I get started on sleep deprivation, run a mile!!).

Stress adversely affects health, but I’m not convinced it caused my cancer. It may have contributed to my cancer diagnoses, though, because I had been harassed by a manager for a decade before cancer showed up. Now I’m dealing with a different health issue that could well be aggravated by horrendous stress caused by a wayward spouse. So it’s an important topic that needs to be addressed. I believe further research is warranted to determine whether stress can lead to progression of cancer. xo
