Lumps in the underarm
Lumps in the underarm or axillae as medically described are fairly common. The most common cause is due to inflammation of the hair follicles in the axillae. Usually, this is a self-limiting condition, however, occasionally the inflammation can flare up requiring topical antibiotics or sometimes requiring minor surgical procedure known as incision and drainage of the abscess.
Rarely a persistent painless lump in the axilla must not be ignored as it could be an enlarged lymph node suggestive of underlying breast cancer or inflammation.
