Retinal cancer is a rare type of cancer that occurs in the retina, the light-sensitive layer at the back of the eye. It can affect both children and adults, but it is more common in children, often presenting as retinoblastoma. Symptoms may include vision problems, eye pain, or a noticeable change in the appearance of the eye. Diagnosis typically involves a comprehensive eye examination and imaging tests. Treatment options may include radiation therapy, chemotherapy, or surgery, depending on the cancer's type and stage. Early detection is crucial for improving outcomes and preserving vision.
