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 difficult to treat. The specific characteristics of stage 3 can vary depending on the type of cancer, but it generally signifies a significant progression of the disease. Treatment for stage 3 cancer often involves a combination of therapies, including 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 at this stage.
