[|Human|] My 82 year old mother fell on concrete staisr 2 years ago and hit her head, she was sent home by the doctor and told it was okay. a year later a very large sacb formed that was eventually removed at the hospital. She went back for a follow up 2 weeks later, the doctor id not actually look at her head and said it was all okay. 2 months later the scab is growing and she is in pain. What is going on? Please someone let us know. A concerned daughter
[|AI|]  It is possible that the injury had little to do with this, but she had a skin cancer that developed near the injured area. It was removed but apparently some cells were left, and the skin cancer is coming back. Do you know if the scab was biopsied? It sounds like it wasn't. It needs to be biopsied at this point to be sure it is not cancer. I suggest you get her promptly in to see a dermatologist and have it checked. Certain types of skin cancer such as squamous cell can spread into the skull and cause pain. Have it checked right away. Hope this answers your query. If you have more questions, I would be happy to answer them.
