Signs and symptoms of eye cancer include loss of a portion of the field of vision, the appearance of a spot on the iris and difficulty in seeing, according to Cancer.Net. People with eye cancer may also see flashes of light, spots, floating objects or wavy lines.
Individuals with iris melanoma usually have visible dark spots on the eye, notes Cancer.Net. Loss of vision without pain is a typical eye cancer symptom. While symptoms of eye cancer occur in many people, some individuals do not experience them, particularly those with intraocular melanoma. In some cases, the symptoms indicate a different medical condition. It is essential for patients to see an eye specialist to confirm the presence of an intraocular melanoma and undergo a diagnosis.
Eye cancer refers to various types of tumors occurring in different parts of the eye, explains Cancer.Net. It results from the uncontrollable growth of cells in or around the eyes, creating a tumor. Some tumors are noncancerous, while others are cancerous and capable of spreading to other areas of the body.
The most commonly occurring primary intraocular cancer in adults is melanoma, which starts when the colored eye cells known as melanocytes grow incessantly, states Cancer.Net. An intraocular cancer is a type of cancer that forms in the eyeball. Less common intraocular tumors include intraocular lymphoma, retinoblastoma and hemangioma.
