Through an xray doctors found a cyst-like mass in my 9 year old daughter's femur. what can we expect moving forward?

Benign or not: Cysts located within the bone may be a benign process by nature (not cancer) but still weaken the bone. They are often found during x-rays for other issues. Some can be a bone cancer. I send my kids to the pediatric orthopedist that works with the oncology group at a children's hospital if the radiologist can't convince me it is benign.
