Proton therapy in Head and Neck Cancer-A Review

Conventional radiation therapy is one of the most common methods of cancer treatment. Because of conventional therapy's early and late toxicity, it is of great interest to find a modality that has low side effects to the normal tissues. This has led to the invention of proton therapy. Proton therapy is believed to have better results than conventional radiotherapy. Proton beam therapy is a recent modality that is more tumour conservative than photon beam therapy. The physical property of protons spares the normal surrounding tissues. More clinical trials and prospective studies are required for the inclusion of proton therapy in treating carcinomas of the head and neck.
