My grandmother developed this strange lump on her wrist overnight. What could this be? I am worried because it looks abnormal

Ganglion cysts typically present as a visible lump on the wrist or hand that may vary in size over time. These cysts are usually painless, but they can cause discomfort or pain if they press on nearby nerves or joints. The skin over the cyst may appear smooth, and the lump itself is often mobile beneath the skin.

In some cases, a ganglion cyst may restrict joint movement or cause a dull ache, particularly if it is located on the wrist. The size of the cyst can also fluctuate, sometimes becoming larger with increased physical activity involving the affected joint.

While ganglion cysts are a common cause of wrist lumps, other possibilities exist. These include lipomas, which are soft, fatty lumps that grow beneath the skin, and are usually harmless. Another possibility is a bone spur, which is a bony growth that can develop in joints due to arthritis or other degenerative conditions.
