Are you at a cancer research hospital. I find it interesting that letrozole is supposed to shrink the tumor. I looked it up at MD Anderson as i am on it because it is to stop the estrogen production.
Your tumor may not be very big? Did you have a biopsy or any test? You seem to be in the natural progression for care. Next you see the cancer psychologist. Have you seen a medical oncologist? If you had all the tests, then they come up with the plan for your cancer. All cancers have a different treatment plan.
