Other types of cancer treated with proton therapy includes lung cancer, liver cancer, prostate cancer and cancer of the head and neck, including cancer of the nasal and sinus cavity, reports Cancer.net. Physicians also use proton therapy to treat noncancerous brain tumors and sarcomas, which is cancer found in the bone or soft tissue of the pelvis and spine.

Proton therapy may also treat lymphoma, mesothelioma, cervical cancer, breast cancer and gastrointestinal cancer, including cancer of the colon, kidneys, pancreas and esophagus, according to Roberts Proton Therapy Center at Penn Medicine. A physician may use proton therapy as a potential treatment method for pediatric cancer, cancers that are reoccurring, and cancers that surgery cannot completely remove from the body.
