The myths about cancer risk are both sad and dangerous. Too many times, I read about supplements or diets that stop “cancer” as if it’s one disease (it is not) that a handful of blueberries will destroy. Like almost every cancer, reducing breast cancer risk really boils down to a handful of lifestyle choices.
In 2015, there will be 232,000 new breast cancer cases in the USA (pdf). Worldwide in 2012, it was estimated that there were over 1.7 million new cases of breast cancer. There is evidence that the rate of breast cancer is increasing, but that may be a result of better diagnostic tools that give earlier diagnoses (and this is a discussion left for another day).
Breast cancer has become a part of our culture, partially because the disease moved from a disease that was only mentioned in whispers to one that has some of the highest awareness for cancers.
Using a review article, by Max Dieterich et al. about breast cancer risk and lifestyle influence as a template, I thought it would be prudent to list out some of the major influencers on breast cancer risk. And no, smoking weed has no known influence on the risk of breast cancer.
