Thank you for your kind comments. You ask, "why do you think the cancer has re-occurred?" I don't understand your question. My Oncologist has
prescribed a needle biopsy to get a conclusive determination of whether there has been a re-occurrence.. My original query, specifying the information in the test results report, was made to get an idea of the odds that the cancer has returned. Regarding the scan, it was part of a monitoring protocol of PET scans every three months post-op. No, at the time chemo was ruled out as previously explained, no prophylactic treatments were prescribed. Immunotherapy is considered by my health insurance provider a second line treatment.....only covered upon re-occurrence. If the biopsy determines a re-cccurrence, treatment options will be considered.
