Although it's not the same thing as uveal melanoma, it's possible for a cancer that originates somewhere else in the body to spread to your eyes. These cancers, called secondary eye cancers, often happen in your choroid, the layer of blood vessels surrounding your eye. These types of cancers are called choroidal metastases, and they may have some of the same symptoms and treatments as uveal melanoma. The most common cancers that may spread to your eye include breast, lung, and prostate cancers. It's also possible to develop melanoma on your eyelid or elsewhere in your eye, which may affect your eyes and vision.
