Hi All I consider myself very fortunate that over the passed 4 years my pet scan results has not shown any or very little met progression. The mets started in l1 ,l2 and l3. I have been on tamoxifen, letrozole and everolimus and afinitor. I have pet scans every 5 to 6 months . I saw my oncologist last week and my mets had spread to t2,t3,7th rib, both hips, l4 and sacrum. The oncologist wants to start me on Ibrance in a few weeks after I complete my radiation appts. My question is .. Is anyone on fentanyl patches and taking Ibrance. I understand there maybe a drug interaction. It makes me nervous. I hesitated to post my test results but I would not have been fair to myself or all of you. Take care
