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 can be used alone or in combination, depending on the type and stage of cancer. In recent years, targeted therapies and immunotherapy have gained attention for their ability to specifically attack cancer cells while minimizing damage to healthy tissue. Ongoing research continues to explore new treatment options and improve existing therapies, aiming to enhance patient outcomes and quality of life.
