Radiotherapy takes many forms: from directing powerful high-energy beams toward specific areas of the body to placing radioactive seeds right next to tumors.

Compared to traditional radiation, proton therapy for cancer lowers risk of side effects and reduces the need for unplanned hospitalizations.

Higher doses of proton therapy over a shorter amount of time effectively treats prostate cancer—and is safe for patients, a new study shows.

"We need to look at the biological factors that are making females more vulnerable to life-saving radiation treatment."

Proton therapy doesn't lead to as many side effects as traditional X-ray radiation therapy for cancer, and has similar cure rates, research finds.
