With this technique, doctors can more easily protect nearby normal tissues from radiation. 3 After surgery to kill any cancer cells that remain.

Why is hypofractionated whole-breast radiation not used?
Another reason that hypofractionated whole-breast radiation therapy isn’t used as often as it could be may be because the ASTRO guidelines stop short of recommending the shorter schedule as a standard of care that can be used in place of traditional whole-breast radiation.
