Six weeks ago I finished 41 radiation and 7 Chemo sessions to treat a base of the tongue cancer with lymph nodes involvement. The treatment went as expected and I'm still recovering. I'm not able to eat or drinks normally, but I have the peg tube. Yesterday I had a CT Scan and the results are good, there is nothing that looks abnormal. However my doctors want to perform a modified radical neck dissection, jut in case there is still some cell lingering there. Now my question, how much will this set me back in my recovery, what are the permanent side effects of this surgery, what is the recovery time like.??? I've read different opinions, some people say its grueling, that they live in constant pain and are at the mercy of pain killers for life. Please if you have gone through this let me know. Please help me take decide weather to have the operation or not.

Thanks
