How common are benign bone tumors?

Benign bone tumors are most common in people who are under 30 years old. A large portion of benign bone tumors are found in children while their skeletons are still growing.

Many benign tumors actually stop growing once a child reaches skeletal maturity, which is the term used to describe the time at which bones stop growing in length. Skeletal maturity usually happens between the ages of 14 to 16 in girls and between the ages of 16 to 19 in boys.
