Breast Cancer

Cancer of the breast takes many forms. All involve the multiplication of cells whose genetic material has changed, which pathologically now causes these cells to multiply without their usual restrictions. Cancer of the breast may metastasize, growing at distant sites such as lymph nodes, bone, or liver. The most common symptom is a lump in the breast, although most such lumps are not cancer, and are benign. The most common site is the upper outer region of the breast. Medical treatment includes surgery, chemotherapy, imunotherapy and radiation. Mortality from breast cancer has been dropping over the past 30 years due to earlier detection and more effective treatment. A 2014 meta-analysis showed that women who engaged in the highest levels of physical activity after being diagnosed with breast cancer had a 29% lower risk for breast cancer–specific mortality and a 43% lower risk for all-cause mortality compared with inactive patients Translational Cancer Mechanisms and Therapy Jennifer A.

Both groups had surgery within one month of starting the study.
