An ultrasound can show the size, shape, location and mass of a cyst, according to WomensHealth.gov. Cysts grow for a variety of reasons, including blockage of ducts, infections, inherited diseases and chronic inflammation, states Healthline.
Some medical treatments for cysts include drainage of the cyst with a needle, surgically removing the cyst, and using cortisone injections to reduce inflammation, explains Healthline. Sometimes benign cysts go away without treatment, but in some cases, cysts can refill with fluid even after drainage. Most often, there is no way to prevent cysts. Cysts that cause problems are those that are infected, impact the way an organ functions, are large or are growing in an area that is sensitive.
