Three-dimensional conformal radiotherapy is a form of treatment that involves taking a high dose of radiation and adapting it to the shape of the target organ in three dimensions, while making the dose inside the target organ high where it should be high and low where it should be low.
Traditional prostate cancer radiation therapy is based on artificially determining an area in advance, selecting a relatively large area to irradiate, and averaging the radiation for the selected area, which is very imprecise and can easily damage normal tissues and organs such as the rectum.
In contrast, in 3D conformal radiotherapy, the source is rotated around the prostate, and with computer assistance, the radiation area and dose are reformulated according to the contours of the prostate at each location of the source, thus allowing the prostate area to receive a high dose of radiation while reducing the impact on surrounding healthy tissue.
