Proton therapy can be used for solid tumors that are localized and have not spread to other parts of the body. Solid tumors are cancers that form an abnormal mass (nodule), excluding blood cancers, such as leukemia. We can apply proton therapy to patients with brain and spinal cord tumors (e.g. brain tumors and chordoma), orbit tumor (e.g., melanoma and retinoblastoma), head and neck cancer, lung cancer, esophageal cancer, early breast cancer, prostate cancer, early liver cancer, and cervical cancer, for example. For prostate cancer, choroid tumor, choroid melanoma, chordoma, and early lung cancer, proton therapy could be performed instead of surgery, helping to preserve the affected organs. Children with cancer may experience more severe side effects of radiation than do adults because their organs have not fully developed. Therefore, proton therapy is preferred for children because it minimizes the side effects of radiation. Brain tumors, soft tissue sarcoma, and retinoblastoma in children are particularly suitable for proton therapy.
