Hello. I was diagnosed with Squamous Cell Carcinoma of the oropharynx a year ago last March. I know the diagnosis is in a different area than the larnex, but I believe the treatment is similar. In my case, I received radiation and chemotherapy which I completed last September. The good news is that I am now in total remission of my cancer. I will say, however, that the radiation treatments (I received 33 treatments over 7 weeks. ) were rough. I would tell your brother-in-law to expect by the end of his treatments: dry mouth, much mucus in his throat, loss of taste, pain while swallowing, and loss of his voice. I would also expect weight loss do to being unable to swallow much, if any food. The symptoms were progressively worse toward the end of the 7 weeks and for a month afterwards. I won’t lie; it won’t be easy, but, at least in my case, I did return to mostly normal after about 6 months after my last treatment (my voice returned to normal about 6 weeks after my last treatment). Of course, the best news is that I’m still alive and hope to have a long life going forward. I hope this helps. He can get through it with encouragement from his family and friends, and in my case, a strong belief in God.
