Proton therapy is a highly targeted form of radiation using charged proton particles to attack tumors, usually those found in head and neck, brain, prostate, lung, gastrointestinal and pediatric cancers. These are all cancers that require the most precise form of radiation in order not to damage surrounding tissues, which may later lead to secondary cancers. This is especially important for children with cancer when it is vital to avoid excess radiation to healthy cells that are still maturing and growing.
In a study by Harvard Medical School, half as many people receiving proton therapy went on to have secondary cancers as those on other traditional X-ray therapies. Thatís because the stream of radioactive particles in proton therapy end at the tumor, rather than passing through it to other healthy tissue in the body. So other important organs in the body will not be affected by the radiation. That also means fewer side effects and complications for this painless, non-invasive treatment, which is why proton therapy is often used along with chemotherapy.
