Lymphedema is a common complication of radiation and surgery for head and neck and breast cancer. I experienced such lymphedema myself and greatly benefited from lymphedema reducing therapy. There is a Website that enable anyone to find a local therapist that can work on lymphedema. A link to it is available on my Web site at

I hope this is helpful.
