I was wondering if anyone has had any experience with laser treatment. My father is supposed to have some sort of laser treatment on his esophageal tumor. I am unsure of any more information on the type of laser, as the oncologist will call with more detail soon. He was hoping for my dad to have surgery, but 2 surgeons agree that dad has lost too much weight. My dad has lost about twenty pounds, but he was always a very thin man. Any feedback appreciated...Thanks.
