What causes frequent itching of the breasts?

Itchy breasts can be caused by various factors:

1. Physiological causes: Women may experience itchy nipples before menstruation or during pregnancy due to hormonal changes, particularly fluctuations in estrogen levels. This is usually related to normal growth and development and does not require special treatment—maintaining proper nutrition is sufficient.

2. Lifestyle factors: Prolonged exposure to hot, humid environments or wearing thick bras can cause poor skin ventilation in the breast area, leading to itching.

3. Medication irritation: Certain medications, such as penicillin or antihistamines, may trigger allergic skin reactions, including itchy nipples.

4. Medical conditions: Diseases such as mastitis, breast eczema, atopic dermatitis, or Paget's disease (a type of breast cancer resembling eczema) can all cause breast itching.

If symptoms worsen or persist without improvement, prompt medical evaluation is recommended.
