A Randomised Trial of Accelerated Partial Breast Irradiation


Doctors are always looking for better ways to treat people with breast cancer.  Partial breast irradiation (in comparison to whole breast irradiation) exposes less of the body to a high dose of radiation.  Also, because a smaller area is treated, the size of each radiation treatment can be larger.  This means that partial breast irradiation can be completed in 1 week (2 treatments per day over 5 days for a total of 10 treatments) instead of up to 6 weeks required for whole breast irradiation.

This study compares partial breast irradiation to whole breast irradiation to see if it is effective as whole breast irradiation at preventing breast cancer recurrence, if the side-effects are different, if it is more convenient for women and if it has different effects on the quality of life of women receiving radiation after breast conserving surgery.
