Visual Guide to Cysts
What Is a Cyst?
It’s a lump of fluid, air, or something else. Cysts are very common, and most aren’t cancer. You may need tests (like a CT scan, ultrasound, or biopsy) to confirm that it’s a cyst. Often, cysts don’t need treatment, but your doctor can let you know if yours does. You can get cysts in many different parts of your body, and you may not even know that they’re there.
