Prompt treatment, which may include some combination of drugs, surgery, and radiation therapy, is extremely important for cancerous tumors. These tumors are growths on the surface of a bone that protrude as hard lumps. A person may have one or several tumors. The tendency to develop several tumors may run in families. Benign chondromas, which usually occur in people aged 10 to 30 years, develop in the central part of a bone.
Some chondromas cause pain.
If a chondroma doesn't cause pain, it doesn't have to be removed or treated. If the tumor can't be diagnosed with certainty on x-rays or if it causes pain, a biopsy may be needed to determine whether it's noncancerous or cancerous. Chondroblastomas are rare tumors that grow in the ends of bones. They usually occur in people aged 10 to 20 years. These tumors may cause pain, leading to their discovery.
