What are four treatments for cancer?

The four main types of cancer treatments include:

* Surgery is the oldest and most common treatment for cancer. It involves physically removing the tumor from the body. Surgery may also be used to remove nearby lymph nodes or other tissue that may be affected by cancer.

* Radiation therapy uses high-energy X-rays or other forms of radiation to kill cancer cells. Radiation therapy can be used alone or in combination with other treatments.

* Chemotherapy is a type of drug therapy that uses cytotoxic (cell-killing) drugs to kill cancer cells. Chemotherapy can be given orally, intravenously (IV), or topically.

* Immunotherapy is a type of cancer treatment that uses the body's own immune system to fight cancer. Immunotherapy can be given in a variety of ways, including immune checkpoint inhibitors, adoptive cell transfer, and cancer vaccines.
