Eye Cancer

Eye cancer is cancer of the tissues in and around the eye. The most common type of eye cancer is melanoma, which forms in pigment-causing skin cells. Less common types include hemangioma, intraocular lymphoma, and retinoblastoma. Eye cancer is rare, with around 3,500 new cases diagnosed in the United States each year. The five-year survival rate of eye cancer is around 80% and decreases with the stage of eye cancer diagnosed. Symptoms include changes in vision; seeing flashing lights, floaters, or squiggles; and the appearance of dark spots on the iris. Risk factors include age, personal history of cancer, and family history. Exposure to sunlight and certain chemicals may also be risk factors, but research has been inconclusive. White people are more likely to be diagnosed with eye cancer. Many eye cancers are observed for changes over time rather than treated immediately, but further treatments include surgery, radiation therapy, and laser therapy.
