Ganglion cysts are noncancerous lumps which are most commonly developing along the tendons or joints of your hands or wrists. They can also happen in our feet and ankles. These cysts are typically oval or round and they are filled with jellylike fluid. These small cysts can be pea – sized while the larger ganglion cysts can be around an inch (2.5 cm) in diameter. If these cysts press a nearby nerve, they can be painful. In some cases their location can interfere with the joint movement. If this cyst is causing you problems, then your doctor can suggest draining the cyst using a needle. Also you have an option to make a surgery for removing the ganglion cyst. But if you do not have any symptoms, then you will probably not have a need for treatment. In many cases the ganglion cyst will go on its own. Ganglion cysts are also known as Bible cysts. It is known fact that they are more common in women and 70% of the ganglion cysts are happening in people who are between ages of 20 and 40. There are very rare cases when ganglion cysts can happen in children who are younger than 10 years. Also it is known that they are happening most commonly on the back of the hand at the wrist joints but also they can develop on the palm side of the wrist. When ganglion cysts are found on the back of your wrists, they become more prominent when the wrist is flexed forward. Also they can be found at the top of the foot and the outside of knee and ankle. Also they can be located at the fingertip, just below the cuticle and if they are here, then they are known as mucous cysts. They can be located at the base of the fingertips on the palm, where they appear as small pea – sized bumps. Ganglion cysts are usually soft, anywhere from 1 – 3 centimeters in diameter and they do not move. When the ganglion cyst is connected to a tendon, then you can feel a sense of weakness in the affected finger.

Causes for ganglion cysts
The exact cause for the development of ganglion cysts is not known. Ganglion cyst grows out of a joint or the lining of a tendon and it looks like a tiny water balloon on a stalk and it seems to happen when the tissue which surrounds a joint or a tendon bulges out of a place. Inside the ganglion cyst there is a thick lubricating fluid which is similar to that found in joints or around tendons.
Risk factors: Here are some factors that can increase your risk of ganglion cysts:
- Join or tendon injury: If you have injured your joints or tendons in the past, then they are having an increased risk of developing ganglion cysts.
