Melanoma is a very aggressive type of cancer that can spread rapidly.
Melanoma of the eye can affect several parts of the eye, including the:
- Ciliary body
The choroid layer is the most likely site of melanoma in the eye.
The cancer may only be in the eye. Or it may spread (metastasize) to another location in the body, most commonly the liver. Melanoma can also begin on the skin or other organs in the body and spread to the eye.
Melanoma is the most common type of eye tumor in adults. Even so, melanoma that starts in the eye is rare.
Too much exposure to sunlight is an important risk factor. Persons who have fair-skin and blue eyes are most affected.
