We have started to use the Civco Radiation Bra for large pendulous breast still using a breastboard. The bra lifts the inferior portion of breast and has been successful eliminating lateral folds. Civco is currently improving the bra to give more support and larger cup sizes for plus sized patients. Added bonus, OSMS can be used for setup and treatment. You can draw an ROI over the mess material of bra just like a breast without the bra. I would be happy to share more if needed.
