Context: Treatment Option Overview / Seven types of standard treatment are used:
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. External radiation therapy uses a machine outside the body to send radiation toward the area of the body with cancer. Sometimes, total skin electron beam (TSEB) radiation therapy is used to treat mycosis fungoides and Sézary syndrome. This is a type of external radiation treatment in which a radiation therapy machine aims electrons (tiny, invisible particles) at the skin covering the whole body . External radiation therapy may also be used as palliative therapy to relieve symptoms and improve quality of life.
Ultraviolet A (UVA) radiation therapy or ultraviolet B (UVB) radiation therapy may be given using a special lamp or laser that directs radiation at the skin.
