Can a dexa scan show if cancer is in the bones? My husband has advanced prostate cancer,did radi for 9 weeks,the Dr still says not sure if that worked?? He has really bad bone pain,is on Morphine x2 daily with little relief,had a bone scan that one Dr says showed alittle uptake in hips,but the only thing they want to do right now is this dexa,I just need to know if cancer will show up in this! Thank you,from a worried wife!! He is 6 3 238lbs
