Comfort Slings are soft tubular cushions on adjustable straps that are sold as single slings to fit under a single breast or as double slings to encompass both breasts at once. I began using the single sling the minute I started my radiation treatment. It protected the area beneath my breast from accumulating perspiration and prevented the abrasion of skin rubbing against skin. By the conclusion of my treatments, the area had darkened slightly but there was no irritation, no broken skin. The sling undoubtedly minimized the side effects of radiation. After my radiotherapy was completed I switched to wearing the double sling – especially during the summer as a simple and effective means to keep me irritation-free. I haven’t had a need for prescriptive topical medications since Look it up:ComfortSlings.com.
