Radiation therapy is an effective treatment method that involves using a high-energy beam to destroy cancer cells. The two types of radiation used to treat eye cancer are external beam radiation and brachytherapy. External beam radiation is recommended for eyelid tumors, lymphoma, and orbital tumors. However, it kills cells from the surrounding area as well. Brachytherapy, on the other hand, is more sparing because the radioactive plaque is custom made to the dimensions of the tumor, so no surrounding tissue or cell is harmed. The rice-sized plaque is surgically placed directly on the tumor to kill cells and reduce its size. Possible side effects include dry eyes, loss of eyelashes and cataracts.
