6. Tumors of the Iris

As unlikely as it may seem, the iris of the eye can also be affected by cancer, with tumors growing right underneath it. According to Healthline, “Most iris tumors are cysts or pigmented growths (like moles), but some are malignant melanomas (a form of aggressive, life-threatening cancer).”

Healthline also states that this is a condition that mostly doesn’t present with any other symptoms, although sometimes “changes in the eye’s appearance can be seen. Thick, pigmented spots called nevi can change, grow larger, or pull the pupil in a different direction.”

If you suspect that you have an eye tumor, it is imperative that you consult a specialist immediately. Your doctor will be able to determine the seriousness of the condition and provide necessary treatment options (which may involve radiation therapy or surgery).
