A cyst is a sac or pocket filled with fluid, air, or other material that can develop in various parts of the body.
Cysts are typically benign and can vary in size. They may form for a variety of reasons, including infections, blockages of ducts, or developmental abnormalities.
Cysts can occur in organs, tissues, or bones, and they are often painless.
While many cysts do not require treatment, some may need medical intervention, such as drainage or surgical removal, especially if they become painful, infected, or impact normal bodily functions.
