what are ganglion cysts from?

The cause of ganglion cysts is not known. One theory suggests that trauma causes the tissue of the joint to break down, forming small cysts that then join into a larger, more obvious mass. The most likely theory involves a flaw in the joint capsule or tendon sheath that allows the joint tissue to bulge out.

Experts believe that the cause of a Bartholin's cyst is a backup of fluid. Fluid may accumulate when the opening of the gland (duct) becomes obstructed, perhaps caused by infection or injury. A Bartholin's cyst can become infected, forming an abscess.

Most ganglion cysts are not painful. Occasionally a cyst may cause a dull ache or pain if it is "squeezed." For example, a cyst on the top of a person's wrist may cause pain when he or she does a push-up.

A cyst is a sac that may be filled with air, fluid or other material. A cyst can form in any part of the body, including bones, organs and soft tissues. Most cysts are noncancerous (benign), but sometimes cancer can cause a cyst.

Earlobe cysts are saclike lumps made of dead skin cells. They look like small, smooth bumps under the skin, similar to a blemish. They vary slightly in color from matching your skin pigmentation to red. Usually they are no bigger than the size of a pea.

Ganglion cysts are a common condition that can develop on the top or bottom of the foot. They are not harmful or cancerous, although they may cause discomfort. Ganglion cysts that are painful or interfere with walking are treated first with non-surgical methods, or surgical removal, if needed.

Ganglion cyst. Ganglion cysts are lumps that most commonly develop in the wrist. They're typically round or oval and are filled with a jelly-like fluid. Ganglion cysts are noncancerous lumps that most commonly develop along the tendons or joints of your wrists or hands.

Pain. Ganglion cysts usually are painless. But if a cyst presses on a nerve — even if the cyst is too small to form a noticeable lump — it can cause pain, tingling, numbness or muscle weakness.

Cysts are common and can occur anywhere on the body. They are often a result of infection, clogged sebaceous glands, or piercings. Some other common causes of cysts include: tumors.

Cervical cysts aren't cancerous. The most common variety is a nabothian (nuh-BOW-thee-un) cyst, which forms when normal tissue on the outer part of the cervix grows over the glandular, mucus-producing tissue of the inner part of the cervix. When mucus, fluid or tissue becomes trapped, a cyst forms.

Renal Cysts. Renal cysts are sacs of fluid that form in the kidneys. They are usually characterized as "simple" cysts, meaning they have a thin wall and contain water-like fluid. Renal cysts become fairly common as people age and usually do not cause symptoms or harm.

Tarlov cysts are fluid-filled nerve root cysts found most commonly at the sacral level of the spine – the vertebrae at the base of the spine. These cysts typically occur along the posterior nerve roots.

Ganglion cysts may grow back after treatment if the “root” of the cyst—the part that connects it to the joint or tendon—is not removed. Cysts are less likely to return if surgically removed rather than aspirated, because in aspiration, the root is only partially removed.

What are synovial cysts? Synovial cysts are small, fluid-filled lumps that tend to form on the lower spine. These cysts are not cancerous and often do not cause any symptoms. However, they can sometimes lead to problems such as sciatica.

Skin Cysts Cysts are common on the skin and can appear anywhere. They feel like large peas under the surface of the skin. Cysts can develop as a result of infection, clogging of sebaceous glands (oil glands), or around foreign bodies, such as earrings.

Cysts may occur when oils are produced in a skin gland faster than they can be released from the gland. They can also occur if the oil gland opening has become blocked and a cyst forms under the skin. Benign bony tumors of the ear canal (exostoses and osteomas) are caused by excess growth of bone.

Cysts are abnormal, fluid-filled sacs that can develop in tissues in any part of the body. They are relatively common, and there are many different types. Infections, tumors, parasites, and injuries can cause cysts. They are usually noncancerous.
