Cysts are closed sac-like or capsule structures that may be filled with semisolid material, gaseous material, or liquid. There are several causes of cysts, including genetic, infectious, and other causes that result in hundreds of types of cysts.
Risk factors for developing a cyst are related to the underlying causes of the cyst formation. Most cysts are asymptomatic and have no signs. However, some cysts on the skin, mucous membranes, and those located in palpable organs often can be felt as a lump or bump; sometimes they are painful.
Some cysts may produce symptoms related to the organs in which they are located (for example, liver, pancreas, or kidneys). It's possible to diagnose cysts by palpation, ultrasound, X-rays, CT scans, MRI scans, and needle biopsies.
Most cysts do not require treatment, however, physicians may use needle aspiration or surgical removal to treat some cysts.
