Some are watched, and some are filled or removed if they weaken bone.

Most bone cysts are not cancer.

Causes

Unknown.

Does it spread or run in families?

• It isn't contagious. You can't catch it from someone else.

Treatment

Treatment depends on the cause and how severe it is.

• Avoid contact sports if the bone is weak

Which doctor treats this

• Start with your primary care provider (family doctor or internist).
• They may send you to an orthopedist (bone and joint doctor).
• A physical therapist can help with exercises to rebuild strength and motion.

Children, pregnancy, and older adults

• Children and teens: Simple bone cysts are common.

Pregnancy and breastfeeding

• If you're pregnant or planning to be, tell your prenatal provider about this condition.
• Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
• Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
• Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.

Outlook

Most never cause problems.

Many heal on their own.
