What type of tumor develops on a tendon and may appear on the back of the wrist?

A ganglion is a type of tumor that typically develops along tendons or joints and is most commonly found on the back of the wrist. These tumors are usually filled with a jelly-like fluid and can vary in size. Ganglions are often benign and may fluctuate in size or may even disappear over time. Their origin from the synovial tissue surrounding tendons or joints is what makes them distinct in this context.

In contrast, arthralgia refers to joint pain and does not directly relate to the formation of tumors. Circumduction is a type of movement involving a circular motion of a limb, not related to tumor development. Osteoarthritis is a degenerative joint disease characterized by the breakdown of cartilage, but it is not a type of tumor.
