Breast Cancer Prevention

What makes a patient chose not to undergo treatment, a decision that can reduce the risk of cancer by upwards to 30%? Facts or beliefs? (And another thing: Why do we pay so much attention to that homunculus jabbering away in our heads?)
In recent years a surprising amount of the orthodoxy of modern medicine has been challenged, and this has resulted in some counterintuitive, even surprising findings. For example, the PSA test for detecting prostate cancer is so flawed that some healthcare professionals are in favor of doing away with it entirely. The primary reason: too many false positives, leading to unnecessary (and very invasive) procedures, with very few lives actually saved.
The U.S. Preventive Service Task Force (USPSTF) evaluates evidence and provides screening guidelines for a number of diseases, including breast cancer. It has just updated its previous guidelines for breast cancer screening in women who have no personal history of cancer, but have a family history that indicates an increased likelihood of potentially harmful BRCA-related cancers.

The American Society of Clinical Oncology took a major step towards making progress in preventing breast cancer and updated their 2009 guidelines. The updates include recommendations that tamoxifen and raloxifene (Evista) should be discussed as options to reduce risk of invasive, ER-positive breast cancer in pre- and post-menopausal women at higher than usual risk of the disease, instead of simply may be discussed.

New York, November 16, 1998 The American Council on Science and Health (ACSH) today rejected the irresponsible and unfounded claims pushed by NBC Chief Medical Correspondent, Dr. Bob Arnot in his book, The Breast Cancer Prevention Diet: The Powerful Food, Supplements, and Drugs That Can Save Your Life. ACSH found that Dr. Arnot s book is a misrepresentation of science and a disservice to women. In an effort to offer a more scientific perspective on the subject of breast cancer prevention, ACSH today issued a peer reviewed critique refuting the specific recommendations and claims set forth in Dr. Arnot s book.
