Things are looking good for you, Tower!
On the dental front, I, too, had a lifetime of fillings in every tooth. Some marginal ones were extracted prior to radiation, but several did not come through the rad well and had to be extracted post-rad. This involved hyperbaric treatments, which are not painful, but are very time consuming and available at only a few places, followed by implants. If I had known before what I learned later, I would have chosen to have more teeth extracted earlier. Bottom line, see a dentist who is familiar with radiation for an evaluation of the health of your teeth.
Having your family close will help a lot as you go through treatment. I am very happy that this is working out so well for you.
