Cancer causes are supposedly:
- 66% - mutations when cells replace themselves
- 29% - environmental factors
- 5% - hereditary factors
As a normal part of life, cells divide and multiply and little mistakes happen all the time. Its just that sometimes they turn into cancer....
"Lifestyle factors still matter for cancer prevention.
Just one mutation is not sufficient to cause cancer -- typically three or more mutations must occur, Tomasetti noted. If, say, your cells miscopy DNA and so cause two random mutations, a third mutation is still needed. Obesity, smoking, lack of exercise and poor eating habits might supply that necessary third gene defect that tips your body into a disease state."
So go eat a salad, quit smoking, and go to the gym. And for those of us who were already doing all of those and still got cancer, can we please just blame bad luck and not blame ourselves?
