Eye tumors occur when there is abnormal cell growth in the eye. These tumors can appear in all parts of the eye, from the lids, iris, to the retina, which is in the deepest part of the eyeball. There are eye tumors that are benign and malignant, depending on the speed of growth and spread to other organs. Benign tumors do not spread to other organs, while malignant tumors can grow quickly and spread to other organs of the body. This malignant tumor is also known as eye cancer. Both benign and malignant tumors often do not cause any symptoms in their early stages. This makes many people do not realize that they have this disease. To prevent the development of tumors or eye cancer, it is necessary to do an early examination and treatment from an ophthalmologist who is an oncologist.
