Lymph nodes are like the body's first line of defense against cancer. When cancer cells spread, they often head straight to the sentinel lymph node (SLN). This is the first lymph node they encounter. Doctors use the SLN to predict how bad the cancer might get. If cancer cells are found in the SLN, t
Obesity is a major risk factor for breast cancer. Many women avoid taking tamoxifen, a drug often prescribed to lower breast cancer risk, because of its unpleasant side effects.
