Cancer Metastasis
Cancer metastasis is the spread of cancer cells from the primary tumor site to other organs in the body. It is a major cause of cancer-related death, as cancer cells that have spread to other organs can be difficult for doctors to treat. Metastasis is occurring when cancer cells detach from the primary tumor and travel through the bloodstream or lymphatic system to other parts of the body. There are a variety of treatments available for metastatic cancer, including surgery, chemotherapy, radiation therapy, hormone therapy and immunotherapy. Improvements in early detection and treatment of metastatic cancer may lead to more positive patient outcomes.
