What is a ganglion cyst?

A ganglion cyst is a small, circular growth filled with a jelly-like fluid, emerging on top of a joint capsule or tendon sheath. Most commonly, they range from roughly the size of a pea to about an inch and a half across, can grow or shrink (or even disappear over time), and are usually found on the wrist or top of the foot.

Also known as “Bible bumps,” these growths are benign, non-cancerous, and almost never medically serious, although they can cause pain and discomfort or impair mobility depending on their size and location.

It’s not really clear why these masses form—one theory suggests that a damaged capsule or protective sheath allows fluid to leak into a space, causing the bump.

Though they’re often harmless, you should have a suspected ganglion cyst checked out by Harvey R. Danciger, DPM as soon as you notice one. We want to make sure it isn’t something serious, and we can offer treatment options or lifestyle modifications that may help your cyst shrink or even go away.
