Proton therapy clinical trials cover a wide range of cancers


More than 8,400 participants have been or are being recruited from around the world for cancer studies involving proton therapy, according to the National Institutes of Health in Washington, D.C. The nearly 70 studies cover more than a dozen types of cancer. Two other clinical studies are collecting data from approximately 10,000 patients who have already been treated with proton therapy. These studies are being conducted to better understand later effects of proton treatments and to help predict particular patient risks.
