Stage 3 cancer indicates that the disease has spread beyond its original site to nearby tissues or lymph nodes. At this stage, the cancer is more advanced and may be more challenging to treat. The specific characteristics of Stage 3 can vary depending on the type of cancer, such as breast cancer or lung cancer. Treatment options for Stage 3 cancer often include a combination of surgery, radiation therapy, and chemotherapy. The goal is to reduce the size of the tumor, eliminate cancer cells, and prevent further spread. Early detection and intervention can improve outcomes for patients diagnosed at this stage.
