Over a similar period, the percentage of prostate cancer mortalities has reduced by more than 40%. There is now growing evidence that men with low-risk prostate cancer may not benefit from radical treatment. This has created controversy regarding PSA screening practices and the treatment of low-risk prostate cancer due to concerns of overdiagnosis and overtreatment.

Evolution of hypofractionated accelerated radiotherapy for prostate cancer – The Sunnybrook experience

Stereotactic ablative body radiotherapy (SABR) is a newer method of ultra hypo fractionated radiotherapy that uses combination of image-guided radiotherapy (IGRT) and intensity-modulated radiotherapy (IMRT) or volumetric modulated arc therapy (VMAT), to deliver high doses of radiation in a few fractions to a target, at the same time sparing the surrounding organs at risk (OAR).
