my father had a prostate cancer.recently he had bone scan and it shows two dark hot spots in his collar bone.but he is doing well and no any other symptoms like weight loss,loss of apataite,any pain of that bone.so I want to know what is the reason for that spots?
Thanks for your question on Chat Doctor. I can understand your situation and problem. Prostate cancer is known to cause bone metastases. They are osteoblastic in nature. This means bone Mets from prostate cancer are depositing calcium. This appears as hot spot (black) on PET scan. So your fathers PET report is suggestive of osteoblastic bone metastases. Better to consult oncologist and discuss treatment for bone secondaries.
