Your comment about costs raises my "concern" flag, being still in the midst of sorting out bills from almost three years ago (and I have reasonable insurance in the overall scheme of things, after the ultra-high deductible is dealt with).
Have the doctors involved send the information for pre-approval if you can. The surgery and RT can be quite expensive if they are not at least negotiated ahead of time. Just taking your chances with coverage is not wise. Even if the facilities/doctors are out of network, pre-approval at least will let you have some sense of the magnitude of costs, and some sense of what additional documentation/justification may be required. And worst case, if you know that something is really not covered, negotiate like your house depended on it. Fight any battle on your terms, not theirs.
I also had an AFLAC policy from an old job that was still being auto-deducted. I had forgotten about it, but it turned out to be great for RT coverage (wasn't worth much against surgery). Look back and see if you have any "forgotten" policies that pay a daily flat rate.
Getting the details together and making a plan for the financial side is better done before you incur the costs, even if it is just to be sure that everything that isn't covered can be worked into Fed or State tax deductions. You might also approach the American Cancer Society and the Lance Armstrong Foundation about financial assistance resources and assistance with appeal processes. I recently talked to a member of the LiveStrong.org staff in Austin, and was quite surprised about the scope of their services and referral network. One bit of advice though, look up the contact number and call, rather than sign up on line, as some things as simple as shipping costs for otherwise free materials may be waived if you call in person.
