I certainly would not rely on my own reading.
Have you asked your doctor about these areas of concern? What did he say?
If I were unsatisfied with the answers, I would get a second opinion. Get a copy of your ct scan and all other material related to your treatment including the surgical report and take it to a different doctor. I would tell my current doctor what I was doing and I would contact my insurance to be sure I'm covered for a second opinion. Considering that you live in NH, I would go to Boston and see someone at Dana-Farber or Mass General.
