So far, my experience with the professional processes, thanks to all of you who have understood me, has been excellent. You have explained in detail what will happen, and this is very important to me because I need to understand what I am feeling, both psychologically and physically, during the chemotherapy and radiation treatments. At this point, everything has been very easy, as long as I follow the instructions to the letter. I know that later on, when I am undergoing treatment, it will be a little difficult, but I have to do it to remove the cancer from the affected area. Thank you all.
