Did you know?

Breast cancer is the most common cancer among American women. Early cases can often be treated with drugs or with a small operation called a lumpectomy (because it removes a lump). Though a "simple mastectomy" is larger than a lumpectomy, it allows the breast to be reconstructed, using artificial implants or tissue from elsewhere on the body. But "radical mastectomy", which is required when the cancer is at an advanced stage, takes much of the chest muscle and makes reconstruction impossible.
