Photodynamic therapy. Photodynamic therapy (PDT) is a cancer treatment that uses a drug and a certain type of light to kill cancer cells. A drug that is not active until it is exposed to light is injected into a vein or put on the skin. The drug collects more in cancer cells than in normal cells.
Melanoma is a disease in which malignant (cancer) cells form in melanocytes (cells that color the skin). There are different types of cancer that start in the skin. Melanoma can occur anywhere on the skin. Unusual moles, exposure to sunlight, and health history can affect the risk of melanoma.

Skin cancer is the most common type of cancer. The main types of skin cancer are squamous cell carcinoma, basal cell carcinoma, and melanoma. Most deaths from skin cancer are caused by melanoma. Start here to find information on skin cancer treatment, causes and prevention, screening, research, and statistics.
Skin cancer is the most common malignancy diagnosed in the United States, and invasive melanoma represents about 1% of skin cancers but results in the most deaths.[1,2] Since the early 2000s, the incidence of melanoma in people younger than 50 years declined by about 1% per year in men and stabilized in women.
Photodynamic therapy is a two-step process. First, you will first receive a photosensitizer. The drug may be taken by mouth, spread on the skin, or given through an IV, depending on where the tumor is in the body. After 24 to 72 hours, most of the drug will have left normal cells but remain in cancer or precancer cells.
NCI-funded researchers are working to advance our understanding of how to treat melanoma and other skin cancers. Much progress has been made in treating people with melanoma that has spread in their bodies (metastatic melanoma). Yet many people still don't benefit from the newest drugs, and others may relapse after initially successful treatment.
In This Section. Merkel cell carcinoma (MCC) was originally described by Toker in 1972 as trabecular carcinoma of the skin. [1] Other names for MCC include Toker tumor, primary small cell carcinoma of the skin, primary cutaneous neuroendocrine tumor, and malignant trichodiscoma.
Merkel cell carcinoma is a rare type of skin cancer that usually starts in areas of skin exposed to the sun. Sun exposure and having a weak immune system can affect the risk of Merkel cell carcinoma. Merkel cell carcinoma usually appears as a single painless lump on sun-exposed skin. Find out more about risk factors, symptoms, tests to diagnose, prognosis, staging, and treatment for Merkel ...
