Does anyone have any knowledge on radiation fibrosis? Since radiation never leaves your body, it can continue, in some people, and cause progressive damage. I was treated for throat cancer in 2010. Lots of radiation treatments, as probably most of you have been through. I've always had some residual issues, especially in the lung area because radiation created scar tissue. However, in the past 6 months i've been having more and more problems with throat area. Airway narrowing, difficulty in swallowing (especially pills), constant coughing (sometimes to the point that I spasm), excessive mucus. I've been back many times to my ENT as things just get worse. He told me what it was, but said there is nothing that can be done for it. I'm going to get a 2nd opinion, but would love to hear from someone who knows anything about it. Thanks for reading.
