Cancer therapy refers to a range of treatments designed to eliminate or control cancer cells in the body. Common methods include surgery, radiation therapy, and chemotherapy. These approaches aim to reduce tumors, prevent cancer spread, and improve patient outcomes. In addition to traditional treatments, newer options like immunotherapy and targeted therapy are being developed. Immunotherapy helps the body's immune system recognize and fight cancer, while targeted therapy focuses on specific genetic changes in cancer cells. Together, these therapies offer hope for more effective and personalized cancer treatment.
