When treating tumors near the spine, proton therapy reduces the radiation exposure to your lungs,1 limiting breathing difficulties and other side effects that commonly result from X-ray therapy.

Treating tumors near the spine can be challenging. Their location generally makes it impossible to use surgery to completely remove them. In treating them with radiation, it is particularly important to limit the amount of radiation to the surrounding healthy tissue in order to avoid serious, lasting side effects. Proton therapy is able to precisely deliver the radiation dose to your tumor while keeping the dose to nearby critical organs and tissue at tolerable levels, limiting unwanted damage.2,3
