Day 10 #HAWMC Does stress cause cancer?
For today’s prompt, I decided to a random search on the Google search terms here on JBBC. The first one that jumped out on me was this one:
Did stress cause my cancer?
Here’s my answer – as with so many things in our lives, not everyone will agree with me, but here’s how I would answer this question.
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.
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
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?
