One form of cancer that can occur inside the eye.
While there are many lumps and bumps that can occur on, around, or inside your eye, choroidal melanoma is one that deserves concern. It is a primary cancer of the eye, which means it started in the eye and did not migrate from any other part of the body. Since it is malignant, the cancer could metastasize (spread) to other parts of the body. Although some choroidal melanomas are more life-threatening than others, almost all should be treated as if they were malignant. A dilated eye examination with your eye doctor can look for any tumors or irregularities on the inside of your eye.
