It involves placing radioactive pellets or seeds inside a specific area of the breast through a catheter. Also known as brachytherapy, this method is typically used after a lumpectomy or in early stage breast cancer. It involves a large machine that sends beams of radiation to a specific area of your breast where there may still be cancer cells. This is the most common type of radiation therapy for breast cancer. It doesn’t target your entire body like chemotherapy, so there’s a lower risk of harming healthy cells. Radiation therapy can damage the DNA of cancer cells, which helps destroy them. The goal of radiation therapy is to focus on cancer cells that may still be present in specific areas, like the lymph nodes or tissue that was close to the tumor that was removed. It can target specific lymph nodes, tumors, or sites where a tumor was surgically removed. Radiation therapy often follows surgery, especially if there’s lymph node involvement.
