DEar Paula, I think you need to do more reading on the hyperberic chamber. It is used [in my understanding] to promote the healing of wounds that otherwise will now heal. We have been told that patients who have any residual cancer or have not been declared totally cancer free are NOT candidates for the chamber because it would accelerate the growth of cancer cells. And while radiation is a scarey thing, it is doable and as many people here will tell you, one can recover and go forward to a good life. Wishing you all the best luck. Amy
