If you are large-breasted and if the radiation is directed to the underside of your breast, the ComfortSlings products are a game-changer. When I was out and about during my radiation treatments, I wore their strapless cushion inside my bra. As soon as I returned home, my bra came off and I put on the ComfortSling Single Sling, wearing it as many hours of the day as I possibly could, especially while sleeping at night. Additionally, I removed the sling often, lay on my back and applied colorless, odorless gel to my entire breast, including the underside. I remained in position until the gel was fully absorbed (it took seconds); then I immediately returned the ComfortSling to its position beneath my breast. By the treatment’s end, my skin had darkened slightly at the radiation site, but was otherwise unchanged. I had no pain, no broken skin. The protection the sling provided in eliminating perspiration and preventing skin-to-skin abrasion combined with the soothing gel was priceless. http://www.ComfortSlings.com
