Armpit lump |
| Overview Treatment |
| Definition: |
| An armpit lump refers to enlargement of one or more lymph nodes in the armpit(s). |
| Alternative Names: |
| Lump in the armpit; Localized lymphadenopathy - armpit; Axillary lymphadenopathy; Axillary lymphs enlarged; Lymph nodes enlarged-axillary; Axillary abscess |
| Considerations: |
| Lumps in the armpit (axilla) have various causes. Cysts and superficial infections in the skin of the armpit may follow shaving or use of antiperspirants (as opposed to deodorants). This occurs most frequently in adolescents just beginning to shave. Subcutaneous (under the skin) abscesses may also produce large, painful lumps in the armpit. Lumps may be produced by lymph nodes enlarged due to bacterial infections, viral infections, antigenic stimulation (as from vaccinations), and malignancy. A breast self-examination should always include the armpit because breast cancer can enlarge the armpit lymph nodes even when the breast itself seems perfectly normal. Lymph nodes are filters that can catch malignant tumor cells or infectious organisms. When they do, lymph nodes increase in size and are easily felt. |
