What is a ganglion cyst?

1. A malignant tumor on a tendon

2. A benign cyst located on top of a joint or tendon

3. A painful bone disorder affecting the heel

4. An inflammation of muscle tissue

The correct answer is: A benign cyst located on top of a joint or tendon

A ganglion cyst is defined as a benign cyst that commonly appears on top of a joint or tendon, often in the hands or wrists. These cysts are filled with a thick, clear, jelly-like fluid and are generally non-cancerous. They can vary in size and may fluctuate over time, sometimes increasing or decreasing in size with activity or rest. Although ganglion cysts can be painless, they may cause discomfort or restrict movement, particularly if they press against nearby nerves or structures. The characteristics of a ganglion cyst distinguish it clearly from other conditions. While it is not a tumor, malignant or otherwise, it can sometimes be confused with more serious growths, but the key aspect is that it is benign and does not pose a cancer risk. This understanding helps in distinguishing it from conditions such as bone disorders or muscle inflammation, which are categorized separately and have different treatment approaches. Thus, identifying the ganglion cyst as a benign cyst located on a joint or tendon provides a clear and accurate understanding of this condition.
