[|Human|] My mum suddenly had knee pain and it swelled up. She had pain walking so had x ray which showed a large shadow on the outer leg just above the knee. After about a week her knee got better and she could walk again. She had an MRI and has now been referred to an orthopaedic hospital. I m really worried it could be cancer . Is there anything else it could be?
[|AI|]  Dear michellewrench, Good afternoon, You did not mention the findings of MRI reports. Also, it is difficult to comment without seeing the X-ray. By history, it appears she may have developed ligament injury or meniscal injury (a soft bone in joint).  It is very less likely to be a cancer. Kindly go ahead with the treatment/ consultation by orthopedic surgeon. Take care. I wish your mum a fast recovery & good health. Regards.
