H. Glibert Welch, MD – Publishes large study showing mammography does more harm than good in the New England Journal of Medicine.
The treatment benefits that Dr. Welch notes on several occasions in his video, causing a breast cancer mortality decline by about a third since 1990, are largely (if not exclusively) due to the reduction of the cancer promoting affects of hormones produced by the ovaries. This is accomplished in 3 ways: 1) The ovaries are surgically removed 2) The effects of the ovary’s hormones are blocked by medications (tamoxifen and aromatase inhibitors) 3) By chemically castrating a woman with commonly prescribed chemotherapy. Surgery and/or radiation have little to no benefit on breast cancer survival. October is breast cancer “awareness” or “industry” month. You will find the research I published on this subject in a chapter in my “McDougall’s Medicine” book.
