Inside the cyst is a thick, sticky, clear, colorless, jellylike material. Depending on the size, cysts may feel firm or spongy. 1  One large cyst or many smaller ones may develop. 2  Ganglion cysts, also known as Bible cysts, are more common in women, and 70% occur in people between the ages of 20-40.
