When to worry about breast pain: get urgent or prompt medical help if the pain is new, persistent, or comes with other worrying changes like lumps, discharge, or skin changes.

Quick Scoop

When breast pain is usually not serious

Breast pain (mastalgia) is very common and is rarely due to breast cancer.

Often it’s linked to hormones or benign issues and settles on its own.

Common “not-so-worrying” patterns include:

  • Pain that clearly comes and goes with your menstrual cycle.
  • General soreness in both breasts, especially before a period.
  • Aching that improves after your period starts.
  • Mild tenderness that doesn’t affect sleep or daily life.

Red-flag signs: call a doctor

See a doctor soon (within days) if you notice any of these:

  • Pain that lasts more than a couple of weeks without letting up.
  • Pain in one specific spot in one breast (focal pain), especially if new.
  • Pain that keeps getting worse or is disrupting sleep or daily activities.
  • A new lump or thickened area, painful or not.
  • Nipple discharge (especially bloody or clear, from one side).
  • Changes in breast skin (dimpling, puckering, redness, warmth, scaling, “orange peel” look).
  • Nipple changes (becoming pulled in, changing shape, scabbing, or scaling).
  • New breast pain after menopause.

When to seek urgent or emergency care

Get urgent or emergency care if breast pain comes with any of the following:

  • Fever, feeling very unwell, or a hot, red, very tender breast (possible infection).
  • Sudden severe chest pain, pressure, or pain spreading to arm/jaw, shortness of breath, sweating, or nausea (possible heart problem).
  • Rapidly spreading redness, swelling, or severe pain in one breast.

What often causes breast pain

Common benign causes include:

  • Hormonal changes (cycle, perimenopause, some contraceptives or hormone therapy).
  • Cysts or benign lumps.
  • Breast infection or abscess (often in breastfeeding, but can occur otherwise).
  • Muscle or rib pain under the breast (costochondritis, strain).
  • Ill‑fitting bras or high‑impact exercise.
  • Certain medicines (some antidepressants, fertility or cardiac meds).

What to do at home (if no red flags)

If your symptoms don’t have red flags, you can try:

  • A well‑fitting, supportive bra (including for sleep if needed).
  • Over‑the‑counter pain relief like ibuprofen or acetaminophen (if safe for you).
  • Warm or cool compresses on the painful area.
  • Tracking your pain with your cycle and a symptom diary.
  • Reducing caffeine and smoking (evidence is mixed, but some people feel better).

If the pain doesn’t improve after a couple of weeks of this, book a check‑up.

Important: Any breast change that worries you is worth discussing with a healthcare professional—trust your instincts and don’t wait if something feels off.
