A small pimple grew on my armpit

A small lump on the accessory breast under the armpit may be caused by hyperplasia of accessory breast tissue, lipoma or enlarged lymph nodes, and requires observation, drug treatment or surgical resection depending on the specific situation.

1. Hyperplasia of accessory breast tissue

Accessory breasts are breast tissue that has not completely degenerated during embryonic development and are commonly found in the armpit area. Hormonal fluctuations, genetic factors, or external stimuli may cause the accessory breast tissue to proliferate and form small bumps. This condition usually does not require special treatment, but if it is accompanied by pain or discomfort, it can be relieved by applying heat or massage.

2. Lipoma

Lipoma is a benign tumor formed by abnormal proliferation of fat tissue, which often appears as a painless lump under the skin. Axillary lipomas usually grow slowly, are soft in texture, and have clear boundaries. If the lipoma is small and asymptomatic, it can be observed regularly; if it increases in size or affects the appearance, it can be removed through minimally invasive surgery or laser treatment.

3. Swollen lymph nodes

Swollen lymph nodes under the armpit may be a sign of infection, inflammation or an abnormal immune system. Common causes include local skin infection, mastitis or immune diseases. If accompanied by fever, pain or redness and swelling, you need to seek medical attention in time, conduct blood routine examinations, ultrasound and other examinations, and use antibiotics or anti-inflammatory drugs to treat it after the cause is determined.

4. Other possible reasons

Small pimples under the armpits may also be sebaceous cysts, fibromas or other skin lesions. Sebaceous cysts are caused by blocked sebaceous glands and can be removed surgically; fibromas are connective tissue hyperplasia and usually do not require treatment, but if they affect your life, surgery may be considered.

5. Medical advice

If the small pimples under the armpits continue to grow, are accompanied by pain or redness, swelling, or other discomfort symptoms, you should seek medical attention in time for professional examination and diagnosis. The doctor will formulate a treatment plan based on the specific situation, including drug treatment, surgical removal or other intervention measures.

Although small bumps on the accessory breasts under the armpits are mostly benign lesions, you still need to pay attention to their changes. By understanding the possible causes and treatments, you can better deal with this problem and seek professional medical help when necessary to ensure your health and safety.
