Thanks to Elyn Jacobs for providing the enclosed information: There’s a lot of confusion out there when it comes to the topic of progesterone and breast cancer. About 70% of breast cancers are ER+ (estrogen receptor-positive), and most of these breast cancers (about 87%) are also PR+ (progesterone receptor-positive). Hormone receptor status has long been a main factor in considering breast cancer treatment. Many women worry when they hear that their breast cancer is both ER+ and PR+, believing this to be “double trouble.” It is time to set the record straight. Actually, doctors have known for a long time that women with high levels of both estrogen and progesterone receptors (high ER+ and PR+ status) often have the best chance of surviving. Despite this, it appears that some oncologists may not really understand or explain one very key point… While estrogen can fuel a tumor’s growth, progesterone puts the brakes on that growth. Hence, they leave patients in a sea of fear and confusion unnecessarily.
