| Nobody knows what causes this to happen. Cancer specialists don't know, so nobody here will.
Smoking has been linked to lung and some other cancers, and excessive sun exposure to skin cancers - but other than that we're still pretty much in the dark.
Many people, invariably those who have not had or studied cancer, have a pet theory about what causes cancer. You will probably get answers telling you it's down to diet or lack of exercise or some other unproven thing.
That's because it's easier for people who haven't had cancer to 'blame the victim' - to put an individual's cancer down to their lifestyle - rather than accept that it is a random, and still mysterious, disease that can strike any of us at any time
I used to think my organic vegan diet, plus all the juicing and exercising I did, would protect me from cancer. It didn't. Nor did it cure me.
So, the answer to your question is - nobody knows. |
