Hypofractionation

Hypofractionation is a radiation treatment in which small doses of radiation are delivered during multiple treatment sessions that extend over several days.

Hypofractionated radiation therapy is delivered over a shorter period of time (fewer days or weeks) than standard radiation therapy. Hypofractionated Whole-Breast Irradiation (HF-WBI), which is increasingly being used for patients with early stage breast cancer, is less toxic than conventionally fractionated whole-breast irradiation and can reduce patient fatigue post-treatment.
