Different operations are used depending on where the cancer is found. If the nodes involved are in the groin, this operation is called a superficial groin dissection. If the cancer has spread to lymph nodes and also to some surrounding areas, the doctor may have to remove a larger portion of tissue around the nodes. When muscles, nerves, and other tissue in the neck are removed, this is called a radical neck dissection. Radiation may be used alone or before or after surgery.
Chemotherapy uses drugs to kill cancer cells.
Chemotherapy may be taken by mouth or it may be put into the body by a needle in a vein or muscle. Chemotherapy is called a systemic treatment because the drugs enter the bloodstream, travel through the body, and can kill cancer cells throughout the body. Chemotherapy may be used alone or after surgery. Therapy given after an operation when there are no cancer cells that can be seen is called adjuvant therapy. Hormone therapy is used to stop the hormones in the body that help cancer cells grow.
