Hello Theresa and Gary. This is my first time to the forum. I was diagnosed with Large B cell Lymphoma and Squamous Cells on the Tongue. I did not know until recently I have both types. I need all the info you both have. I was happy to hear both of you are doing well with your treatments. This is my 2nd cycle of Chemo then on to Radiation. What exactly is brachytherapy. Never heard of it. I am interested in finding out what I can about Photodynamic therapy (light therapy). How many cycles of chemo did you have?
