[|Human|] My mother has to get an mri because they her bone had an abnormal thickening. What do you think it is ? her numbers are all good otherwise, but her leg has been giving her alot of pain. When she was little she was ran over by a milk truck and in a body cast for along time. Do you think it has anything to do with that? What are the chances you think that its cancer.
[|AI|]  Hi, The problem as you say is pain in the same limb which had the fracture when she was young. Fracture in young age heals well, and the none tends to regain its shape and size and by adult life will be almost normal. If a thickening has been detected then it's a new change resulting from either a hormonal problem or cancer. Hence, an MRI is necessary to study the appearance to reach a diagnosis. If all the blood tests are normal its possible that it may not be from cancer. However, this needs to be investigated. Hope I have answered your question. Let me know if I can assist you further.
