What could breast pain mean?

Breast pain is commonly related to periods, pregnancy, menopause, medicines or pain referred from the chest wall. Pain by itself is unlikely to be breast cancer, but persistent pain or pain with a lump, nipple discharge, skin dimpling, shape change, heat or redness needs assessment.

Is breast pain a sign of cancer?

Pain alone is unlikely to be cancer, but new lumps, nipple or skin changes, or persistent one-sided symptoms should be checked.

Why do my breasts hurt before a period?

Hormonal changes can cause both breasts to feel heavy, aching or tender in the 1 to 2 weeks before a period.

Can neck or shoulder strain feel like breast pain?

Yes. Pain from the chest wall, ribs, neck, shoulder or back can be felt in the breast area.

Breast pain: When to See a GP

Common patterns

Cyclical pain often affects both sides and settles after a period. Non-cyclical pain may come from pregnancy, menopause, medicines, infection or the chest wall.

Self-care

Wear a well-fitted bra and use paracetamol, ibuprofen or pain-relief gel only if suitable. Keep a symptom and menstrual-cycle note to identify patterns.

Changes to check

Do not wait for routine screening if you notice a new lump, nipple discharge or inversion, skin dimpling, breast-shape change or persistent focal pain.
