What causes breast lumps?

A lump in the breast may have the following causes: 1. **Breast hyperplasia**: This is a common cause, presenting as lumps or nodules within the breast. The condition is usually benign but may cause pain or discomfort. 2. **Fibroadenoma of the breast**: This is a common benign tumor, appearing as round or oval firm lumps in the breast. Fibroadenomas are typically painless, although they may grow larger or cause discomfort in some cases. 3. **Mastitis**: Mastitis is an inflammation of the breast tissue that can lead to redness, swelling, pain, and the formation of a lump. It is commonly associated with breastfeeding but can also occur in non-lactating women. If a breast lump is detected, it is recommended to seek medical evaluation promptly.
