You are a boy aged 12 why does there seem to be lump under your nipple and it hurts?

Possible Causes:

1. Gynecomastia: It's not uncommon for boys your age to experience a temporary condition known as gynecomastia, where breast tissue begins to develop under the nipples. This is often caused by the hormonal changes that occur during puberty. Usually, gynecomastia goes away on its own within a few years.

2. Injury: If you've recently injured your chest area, it could be causing pain and swelling around the nipple. Impact injuries or muscle strains in the chest can lead to pain and lumps.

3. Infection: An infection in the breast tissue (mastitis) is rare in males but can occur. It's usually accompanied by redness, swelling, and fever.

4. Underlying Medical Conditions: In rare cases, a lump under the nipple can be a sign of a more serious medical condition, such as a hormonal imbalance or a tumor. However, these are much less likely in children your age.

What to Do:

1. Monitor: In most cases, lumps under the nipple during puberty are harmless and will go away on their own. You should still keep an eye on the lump. If it persists for several months or grows rapidly, you should consult a doctor.

2. Consult a Doctor: If the lump is painful, rapidly growing, or causing any discomfort, it's important to see a doctor. They will be able to examine you and determine the cause of the lump.

3. Avoid Self-Treatment: Do not attempt to self-treat the lump. Some online suggestions may be harmful. Always rely on professional medical advice.

4. Stay Calm: Remember, it's common for boys your age to experience hormonal changes that affect breast tissue. Stay calm and discuss it with your parents or a trusted adult who can help you schedule a doctor's appointment if needed.
