Despite what you may have been led to believe, the rise in the incidence of breast cancer in the last 80 years is apparently not due to hereditary factors!
In my initial blog post, I discussed Angelina Jolie’s recent decision to undergo a prophylactic bilateral mastectomy because she was a BRCA1 gene carrier. While many questioned her need for such a drastic approach to prevention, in light of her strong family history and her lifetime cancer risk, it was an understandable and well thought out choice. In this follow-up post, I want to elaborate on an important issue that I had previously raised and feel has been both overlooked and/or misunderstood by the media and many doctors. Simply stated, the dramatic rise in the incidence of breast cancer over the last 80 years has occurred in both the carriers of such breast cancer genes and in all women, in general, in western countries. How can I make such a bold statement?
As is often the case in scientific inquiry, during the course of my research on breast cancer risks, I stumbled upon an intriguing and unexpected finding.
Let me explain.
