retinoblastoma (Rb)

Retinoblastoma (Rb) is a rare eye cancer that primarily affects young children, often before the age of five. It develops when abnormal cells grow uncontrollably in the retina, the light-sensitive tissue at the back of the eye. Genetics can play a role, but sometimes it occurs without a family history. Early signs may include a white glow in the pupil or crossed eyes. Treatment options include surgery, radiation, or chemotherapy, aiming to save vision and prevent the cancer from spreading. With early detection, the prognosis can be very favorable.
