what is secondary breast cancer

Secondary breast cancer, also known as metastatic breast cancer, occurs when breast cancer cells spread from the breast to other parts of the body. This means that the cancer has advanced to stage 4, and it can spread to various organs such as the liver, lungs, brain, or bones. Secondary breast cancer is diagnosed when breast cancer cells are found in a part of the body other than the breast, and it is treated differently from primary breast cancer. It is important to note that secondary breast cancer is not the same as a new cancer, but rather a spread of the original cancer. Treatment options for secondary breast cancer may include chemotherapy, hormone therapy, targeted therapy, surgery, or radiation therapy, depending on the location and extent of the cancer. It is important for individuals with breast cancer to be aware of the signs and symptoms of secondary breast cancer, such as bone pain, shortness of breath, or headaches, and to discuss any concerns with their healthcare provider.
