What is Ganglion Cyst?
A ganglion cyst is a fluid-filled capsule which usually occurs over the back of the hand, wrist, foot, ankle, elbow, shoulder.
These cysts can appear, disappear or change in size but in most cases are harmless. These are not cancerous and need not be treated, however, if the cyst is painful or has an unacceptable appearance then it might need treatment.
What are the Causes?
One possible cause is the trauma causing the tissue of the joint or tendon sheath to break down forming small cysts, which then join into a larger, more obvious mass. The most likely cause involves a flaw in the joint capsule or tendon sheath that allows the joint tissue to bulge out.
What are the Treatments?
Many cysts (38-58%) disappear without any treatment at all. Treatments include using a needle to remove the cyst’s contents (aspiration). Surgical removal of the cyst is needed when the mass is painful, interferes with function especially when the dominant hand is involved, or causes numbness or tingling of the affected area.
