Article: Understanding a Lump on the Back of the Hand

A lump on the back of the hand, like the one highlighted in the red circle, can be caused by various conditions. Common possibilities include:

1. Ganglion cyst: A fluid-filled sac that often develops near joints or tendons, appearing as a smooth, round swelling.
2. Tendonitis: Inflammation of the tendons can cause swelling and a noticeable bump, usually due to repetitive strain.
3. Lipoma: A benign fatty tumor that feels soft and movable under the skin.
4. Injury or trauma: A bruise or fracture can lead to localized swelling.

Symptoms to watch for include pain, limited mobility, or changes in size. If the lump is painful, growing, or affecting function, medical evaluation is advisable. Diagnosis typically involves physical examination and sometimes imaging (ultrasound or MRI). Treatment ranges from observation to aspiration or surgical removal, depending on the cause.
