What causes itchy breasts?

Possible causes of breast itching may involve multiple factors, mainly including: 1. Physiological factors: Hormonal changes before menstruation may lead to breast sensitivity and itching. 2. Lifestyle factors: Prolonged exposure to hot and humid environments, wearing tight or non-breathable undergarments, or using irritating soaps or cosmetics may cause skin itching in the breast area. 3. Medication irritation: Certain medications, such as penicillin, may cause allergic reactions leading to itching in areas including the breast. 4. Disease-related factors: Breast and skin conditions such as breast eczema, mammary hyperplasia, mastitis, and eczema-like breast cancer may all cause breast itching. 5. Dry skin: Lack of moisturization may result in dry skin, which can in turn cause itching. If breast itching persists or worsens, prompt medical consultation is recommended.
