Context: Treatment Option Overview / The following types of treatment may be used:
Phototherapy uses a drug and a certain type of laser light to kill cancer cells. A drug that is not active until it is exposed to light is injected into a vein. The drug collects more in cancer cells than in normal cells. For cancer in the skin, laser light is shined onto the skin and the drug becomes active and kills the cancer cells. Phototherapy is used in the treatment of cutaneous T-cell lymphoma.
