I had radiation 8 years ago, now my ca is back, both sides of my tongue, right and left and lower front of mouth. Before they discovered the ca had spread to the right side they were going to do radiation implants since I had had external rad prior and could not have it again. Ask your dr. about that. It sounded just what I needed until the other spots shot up. I am getting chemo now before surgery is done again. I really think I can actually feel the tumor on the left side going down. Might be in my head but a good feeling. The implants are called Brachytherapy.
Good Luck to you all and God Bless.
