[|Human|] At the age of 25 I was diagnosed with osteosarcoma of the mastoid process. I have done alot of research trying to see if there have been any other cases like mine, but have not been succesful. If there is any data that you could provide I would appreciate it. Thanks!
[|AI|]  Hi, Thanks for writing in. Osteosarcoma is a malignancy which causes bone forming tumor. Osteosarcoma of the mastoid process is rare, and I have not come across any patient having it. There is literature which shows that surface osteosarcoma is common in patients who are of your age. I am not sure if your osteosarcoma is of a surface type or not. Literature shows that Most osteosarcomas occur in child Chat Doctor.  Teens are the most commonly affected age group, but osteosarcoma can occur in people of any age. It is seen in people at your age. Please do not worry.
