Welcome to the forum, Mary. I'm sorry you have to join our group of friends, but you will find support here and members do care.

I agree that you should see an oncologist. It's good news that your HMO has approved that. Oncologists will have the experience and will have seen many more cases of sac than a general surgeon, for example. If the oncologist feels you need further treatment, then, he or she will probably refer you to a medical or radiation oncologist. Don't blame yourself for not thinking properly. The dreaded word "cancer" throws people off. Your family doctor should have made that referral in the first place, or the surgeon who did the surgery. It's as much their responsibility as it's yours.
