Surgery is often used initially to remove tumors. Depending on the type of cancer, surgery may be performed one time or in several stages. Reconstructive surgery also may be used at this time or later in the treatment process.
Chemotherapy is the use of medicine or chemicals to kill cancer cells. Chemotherapy can be given in different ways. Some chemotherapy medicines are delivered into your veins and take several hours to be given. Other medicines are injected with a needle or given orally in the form of pills or capsules.
Radiation therapy uses radiation to kill cancer cells. As with chemotherapy, radiation therapy can be administered over several treatments and can kill healthy cells.
