A 14-year-old boy has a hard lump in the right breast that is painful when pressed.

A 14-year-old boy experiences a painful lump in the right breast, which may be related to endocrine disorders, gynecomastia, mastitis, or other causes. Treatment should be selected based on the specific underlying cause.

1. Endocrine Disorders

When a patient has an endocrine disorder, hormonal imbalances in the body can lead to a painful lump in the right breast of a 14-year-old boy. Testing hormone levels can help confirm the diagnosis. In daily life, it's important to avoid foods high in estrogen.

2. Gynecomastia

Gynecomastia in males is primarily caused by elevated estrogen levels, leading to the development of a tender lump in the breast. Under certain conditions, this can result in a painful lump specifically in the right breast of a 14-year-old boy. Breast ultrasound can help confirm the diagnosis. In severe cases, surgical treatment may be necessary, involving removal of the breast glandular tissue.

3. Mastitis

If a boy develops mastitis due to breast inflammation, inflammatory stimulation can cause local swelling and result in a painful lump in the right breast. In more severe cases where a breast abscess forms, there may also be a sensation of fluctuation in the affected area. If a breast abscess is present, surgical incision and drainage are required, along with anti-inflammatory treatment using antibiotics to control the infection.

Besides the above causes, conditions such as fibroadenoma or lipoma can also lead to a painful lump in the right breast of a 14-year-old boy.
