When is radiation boost given?

Page last modified on: September 19, 2008
Question from Kaye: When is radiation boost given? I am worried because I didn't have boost. I had bilateral mastectomy; main tumor was in upper inner quad—pleomorphic invasive lobular. Also had tumor in nipple with dermal lymphatics and high-grade DCIS with extensive comedo necrosis.
Answer —Lydia Komarnicky, M.D.: If someone has a mastectomy and radiation therapy is necessary, typically the chest wall is treated, but not necessarily with a boost. The patients who typically receive a boost as part of their radiation treatment planning are those patients who have an intact breast.

In other words, those patients who've not had a mastectomy will require whole breast radiation plus a boost to where the tumor was located. If a mastectomy has been performed, there is no need to have a boost. Although rare circumstances happen where you may, but usually where a mastectomy is performed, a boost is not performed as part of the treatment plan.
