What Causes Cancer?

What causes cancer? When you think of all the things that are known or assumed to be cancer-causing and put them together–you end up with a list that is pretty daunting. This summary comes straight from the book Cancer: 101 Solutions to a Preventable Epidemic (New Society Publishers, 2007) by Liz Armstrong, Guy Dauncey and Anne Wordsworth.

This list does not claim to represent a complete summary of the contributing factors; but it is an indication that there are many more factors than we usually think about. The good news is that many are avoidable. What do you think of this list? Do you take issue with any of the items here? Are there other items that you would add?

Lifestyle and Diet Factors
Smoking and second-hand smoke.
Diet–too much meat, not enough fruits and vegetables.
Suntanning.
Absence of UV sunlight in some regions, reducing cancer-protecting vitamin D.
Obesity, and lack of regular exercise.

Other Food Factors
Processed food such as nitrosamines, aspartame, some food colorants.
Bovine growth hormone in milk.
Some salt-cured, pickled, and smoked food.
Sugar and alcohol consumption.
Absence of cancer-protecting compounds in food not grown organically.
Food contaminated with pesticides and herbicides.

You can't narrow this down, it depends literally on everything.

I very much fear that we are still in the beginning of understanding what causes cancer. My mother was a fanatic vegan, did not smoke or drink alcohol, ate organic food, did not have cancer in the family, but had a huge fear of getting cancer. And she did... Conclusions are yours!
