Mastalgia (Breast Pain): Causes, Warning Signs, Tests & Treatment

Medically reviewed by Prof. Dr. Zahid Mahmood, MBBS, FCPS — General, Laparoscopic & Laser Surgeon, Lahore.

Mastalgia is the medical term for breast pain. It may feel like tenderness, heaviness, burning, aching or a sharp pain. It can affect one breast or both breasts and may arise from breast tissue or the muscles and ribs beneath it.

Breast pain is common and is usually not caused by cancer. However, persistent pain in one specific area, or pain accompanied by a lump, nipple discharge, skin change or fever, needs medical assessment.

What are the main types of mastalgia?

Cyclical mastalgia

Cyclical pain follows the menstrual cycle. It usually affects both breasts, becomes worse during the one or two weeks before a period and improves when menstruation begins. The breasts may feel swollen, heavy or tender, with discomfort extending towards the armpits.

Non-cyclical mastalgia

Non-cyclical pain does not follow a regular monthly pattern. It may occur in one breast or a small localised area. Causes include breast cysts, inflammation, infection, previous injury or surgery, pregnancy, hormonal medicines and, rarely, breast cancer.

Chest-wall pain

Pain from the ribs, muscles, shoulder, neck or nerves can feel as though it is inside the breast. It is often reproduced by pressing a rib, moving the arm or twisting the upper body. Costochondritis, heavy lifting, coughing and exercise-related strain are common causes.

Common causes of breast pain

  • Normal hormonal changes before menstruation
  • Pregnancy, breastfeeding or weaning
  • Perimenopause or hormone replacement therapy
  • Breast cysts and benign nodularity
  • Mastitis or a breast abscess
  • Chest-wall muscle strain or costochondritis
  • Poor breast support during activity
  • Previous breast injury, surgery or radiotherapy
  • Certain hormonal, psychiatric and cardiovascular medicines

Do not stop prescribed medication without speaking to the clinician who prescribed it.

Does mastalgia mean breast cancer?

Pain alone is rarely the first symptom of breast cancer. Concern is greater when pain is persistent and localised or occurs with a new lump, nipple or skin change, bloody discharge, altered breast shape or enlarged lymph nodes. These symptoms still often have a benign cause, but they should be examined promptly.

Warning signs requiring medical review

  • A new breast or armpit lump
  • Persistent pain in one specific area
  • Skin dimpling, puckering, redness or an orange-peel appearance
  • A newly inverted nipple or persistent nipple rash
  • Spontaneous bloody or clear discharge from one nipple
  • A change in the size or shape of one breast
  • A red, hot, swollen breast with fever or feeling unwell
  • New focal breast pain after menopause

A red, painful breast with fever may indicate mastitis or an abscess and needs urgent assessment. New chest pressure with breathlessness, sweating, nausea or pain spreading to the arm or jaw requires emergency care.

How is mastalgia assessed?

The clinician asks about the location, timing and severity of pain, menstrual pattern, pregnancy or breastfeeding, medicines, previous breast problems and family history. The breasts, nipples, armpits and chest wall are then examined.

A pain diary covering one or two menstrual cycles can show whether symptoms are cyclical. Record the painful days, severity from 0 to 10, menstruation, activity and any medicines taken.

Are ultrasound or mammography always needed?

Imaging is not always needed when pain is diffuse and cyclical, examination is normal and no warning signs are present. Imaging is more useful for focal, persistent, non-cyclical pain or an abnormal examination.

  • Ultrasound is generally the first investigation in younger women and during pregnancy or breastfeeding.
  • Diagnostic mammography, often with targeted ultrasound, may be advised according to age and clinical findings.
  • MRI is not routinely used for breast pain alone.

A new lump requires proper breast-lump assessment and should not be attributed to mastalgia.

What can relieve mastalgia?

  • Wear a correctly fitted supportive bra and a sports bra during exercise.
  • Use paracetamol or an anti-inflammatory medicine only if it is safe for you.
  • Try a warm compress or wrapped cool pack.
  • Reduce activities that clearly reproduce chest-wall pain and improve posture.
  • Keep a pain diary to identify a menstrual or activity-related pattern.

People who are pregnant, taking blood thinners, or have kidney disease, stomach ulcers, certain heart conditions or sensitivity to anti-inflammatory medicines should seek advice before taking ibuprofen or similar drugs.

Do caffeine restriction and supplements help?

Evidence that avoiding caffeine, chocolate or specific foods reliably improves mastalgia is inconsistent. A short personal trial is reasonable if you notice a clear trigger, but restrictive diets are unnecessary. Evening primrose oil and other supplements have uncertain benefit and may interact with medicines.

Treatment for severe persistent mastalgia

Most patients improve after reassurance, good support and simple pain relief. Pain that continues to disrupt sleep, work or daily activities may require specialist assessment. Medicines such as tamoxifen or danazol are reserved for selected severe cases because they can cause important side effects and require medical supervision.

Frequently asked questions

Why do my breasts hurt before my period?

Breast tissue responds to normal hormonal changes. Cyclical pain typically becomes worse before menstruation and improves when the period begins.

Can a breast cyst cause pain?

Yes. A tense cyst can be tender. Ultrasound can confirm that a lump contains fluid, and aspiration may relieve a painful simple cyst when appropriate.

Can men develop mastalgia?

Yes. Causes include gynaecomastia, medication, infection, injury and chest-wall pain. A hard one-sided lump, nipple change or discharge requires prompt assessment.

Does normal imaging mean the pain is imaginary?

No. Hormonal and musculoskeletal pain may be significant even when imaging is normal. A normal assessment is reassuring and helps guide safe symptom treatment.

Key message

Mastalgia is common and usually benign. Cyclical pain often affects both breasts before a period, while focal non-cyclical pain may arise from the breast or chest wall. Persistent localised pain or pain with a lump, nipple discharge, skin change or fever requires proper assessment.
