I received this therapy from a highly qualified nurse who is certified to perform it on cancer patients for lymphedema. It has helped me tremendously. The technique is gentler than a traditional massage of this type. My target area is my neck around my neck dissection scar. After 8 weeks I saw good improvement and now I go once a month. I was also prescribed a compression garment I wear nightly. My advice is to seek out a licensed practitioner who specializes in cancer patients. My nurse has these credentials PT DPT CLT-LANA “The Lymphology Association of North America, LANA, is a non-profit corporation specializing in the certification of healthcare professionals who diagnose and/or treat lymphedema and related disorders”
