What might a pea-size bump by the ear be?

A pea-size bump by the ear could be several things, including:

- Swollen lymph node: Lymph nodes are small, bean-shaped glands that help fight infection. When they become swollen, it can be a sign of an infection or other medical condition.

- Sebaceous cyst: Sebaceous cysts are non-cancerous growths that develop from the sebaceous glands, which produce oil for the skin. They are usually small, round, and filled with a white or yellow substance.

- Lipoma: Lipomas are non-cancerous growths that develop from fat cells. They are usually soft, movable, and painless.

- Keloid scar: Keloid scars are raised, reddish scars that can occur after an injury or surgery. They are more common in people with darker skin tones.

- Skin cancer: In some cases, a pea-size bump by the ear could be a sign of skin cancer. This is most likely to occur if the bump is new, growing rapidly, or bleeding.

If you are concerned about a pea-size bump by the ear, it is important to see a doctor for evaluation. The doctor can determine the cause of the bump and recommend treatment if necessary.
