Ganglion Cysts Hand Lumps and Bumps

How to Know If You Have a Ganglion Cyst

Ganglion cysts are lumps in the hand and wrist that are fairly common. They can occur in people of all ages, and the cause is unknown. Sometimes they are painful, but many times they will not affect you. Here’s how to know that you have a ganglion cyst and not a wart or different type of lump:

  • The lump may be filled with clear fluid or gel.
  • The lump will be oval or round in shape.
  • Light is often able to pass through the lump (transillumination).

Your ganglion cyst may change in size over time or even disappear completely. Some are soft and some are firm. To treat a ganglion cyst, sometimes it may be appropriate to simply do nothing. Other times, your surgeon may recommend a splint, medication, aspiration (removing the fluid with a needle), or surgery.
