Study on Increased Radiation Dose Benefits for Patients with Low-Risk Prostate Cancer

Newswise — PHILADELPHIA – Increased radiation dose is associated with higher survival rates in men with medium- and high-risk prostate cancer, but not men with low-risk prostate cancer, according to a new study from Penn Medicine published this week in JAMA Oncology. Already-high survival rates for men with low-risk prostate cancer were unaffected by higher radiation dosages compared to lower radiation dosages.

In 2014, low-risk prostate cancer was the most common type of prostate cancer diagnosed in the United States, affecting about 150,000 patients, many of whom undergo aggressive treatment, either complete removal of the prostate or radiation.
