Eye cancer is a relatively rare malignancy which occurs in the eyes. It can be divided into eyelid cancer and intraocular cancer according to the sites. Generally, it occurs in a single eye first and subsequently spread to another eye. Its incidence varies in different age.Eye cancer is usually caused by genetic factors or genetic mutations of the patients themselves. Other predisposing factors may include: achromia at the margin of the eyelid; long-tern sun exposure, especially for intense UV radiation; malnutrition and so on.
