1. Surgery: Surgery is often the first line of treatment for cancer, as it is the most direct and effective way to remove cancerous tissue. Depending on the type of cancer and the extent of its spread, the surgeon may remove the entire tumor, some of the surrounding tissue, and sometimes nearby lymph nodes. The goal of surgery is to remove as much of the cancerous tissue as possible, while preserving the health of surrounding tissue.
2. Radiation Therapy: Radiation therapy is a type of treatment that uses high-energy rays or particles to kill cancerous cells. It is usually used in combination with other treatments such as surgery, chemotherapy, or immunotherapy. Radiation therapy is often used to shrink tumors, relieve pain, and slow the spread of cancer.
3. Chemotherapy: Chemotherapy is the use of drugs to kill cancer cells. It is usually given intravenously (IV) or orally (pill form). Chemotherapy can be used to cure cancer, shrink tumors, slow the growth of cancer cells, or relieve pain.
4. Immunotherapy: Immunotherapy is a type of cancer treatment that uses the body’s own immune system to fight cancer. Immunotherapy can be used to treat many types of cancer, including breast, lung, skin, and colon cancer. It is often used in combination with other treatments such as surgery, radiation therapy, or chemotherapy.
