The doctors have doubt. In one MRI report they have written Osteochondroma & another report they have written Chondrosarcoma. Whether Osteochondroma can happen in older people? Or it is certainly Chondrosarcoma or somety else.

My grandmother is of 80 years and doc's are doubting about Osteochondroma & Chondrosarcoma for knee little swelling & pain. I have done mri 2 times- both having different results of Osteochondroma & Chondrosarcoma. Doc is saying there are 99% chance of Chondrosarcoma. Can Osteochondroma happen at this  age? What are the next suggestion.
