Most breast pain is hormonal and varies with the menstrual cycle. It can be linked to cyst formation, heavy breasts, a poorly fitting bra, or tension in the chest wall — often mistaken for breast pain.
When to see a doctor
- The pain is confined to one area and does not go away
- The pain comes with a lump, discharge or skin change
- The pain interferes with daily life
- The pain appears after menopause without an obvious cause
Isolated breast pain, without a lump or skin change, is almost never breast cancer. But persistent or one-sided pain deserves a professional check for peace of mind.
