You NEED a second opinion. Chemo is not curative for SCC. There are better ways to deal with this. Any doctor that is speculating on how much time you have left is guessing. Combine that with a chemo approach to a situation that chemo is not the first tool in the bag for, and I'd want someone else to manage my situation, Ideally a team of people including a radiation doc, and a head and neck surgeon. When they all weigh in on your situation, you will have a better plan, and be working towards complete eradication of this.
