I am really confused and worried. My dad did bone scan 2 weeks ago and there were 2- 3 spots in his ribs. He did CT urogramm and everything was fine. oncologist told my dad to do CT scan of the chest without contrast. urologist is for Pet scan.I don’t understand why the oncologist think it should be a fracture, injury, inflammation and urologist thinkS there are Mets. My question is how can the cancer travel into the ribs if everything is fine around the prostate? can he do only PEts an and skip the CT or he need to do both of them? My dad feels very good except some hot flaches due to the firmagon. The urologist want to switch with Eligard very 6 months and oncologist every 3 months. Really confused..... I appreciate any advice from you. Thank and have a nice day.
