Prostate Cancer Overview
Prostate cancer is the most common cancer affecting men, but treating it with traditional radiation therapy can be difficult. Older radiation delivery methods expose nearby healthy organs to damage.
However, cutting-edge therapies, such as Intensity Modulated Radiation Therapy (IMRT) and Image-Guided Radiation Therapy (IGRT) enable physicians to deliver higher doses of precisely focused radiation to cancerous tumors while sparing nearby healthy tissue. For example, one study compared IMRT to traditional radiation therapy and found that the higher dose rates delivered by IMRT significantly improved the rate of localized tumor control while reducing the incidence of rectal bleeding from 10% to 2% of patients.*
