Proton therapy is one type of radiation technology. Its effectiveness is equal to that of traditional radiation therapy that uses photons rather than proton particles. Proton therapy may be the best choice — or doctors may recommend a different type of radiation therapy technology that is better suited to treat a specific individual’s cancer. The Froedtert & MCW Cancer Network offers a number of highly effective, advanced radiation technologies, including Unity MR-Linac, RadiXact and Leksell Gamma Knife, to name a few.
