Symptoms & Assessment

Breast pain assessment

Breast pain is common and usually benign — most is cyclical mastalgia linked to hormonal changes. Persistent, localised, or new pain warrants specialist assessment, particularly if accompanied by any other change. One-stop assessment where clinically appropriate can combine examination and imaging in a single visit. Dr Fiona Tsang-Wright (GMC 4549831), Consultant Oncoplastic and Reconstructive Breast Surgeon, operates privately in London and Buckinghamshire at the Women's Health Centre – Harley Street, Women's Health Centre - King's Road, and The Chiltern Hospital, and as NHS Consultant at Bucks Breast Unit, Buckinghamshire Healthcare NHS Trust.

Understanding the cause

Quick answers

Is breast pain a sign of cancer?

Pain alone, with no other finding, is an uncommon presentation of breast cancer. Most breast pain is cyclical mastalgia — benign and hormonally driven. Assessment rules out any underlying cause.

What is cyclical mastalgia?

Breast pain linked to the menstrual cycle — usually bilateral, worse before a period, and common in premenopausal women. Benign, but can be significant enough to affect quality of life.

Can I manage it myself?

Cyclical mastalgia often improves with a well-fitted bra, anti-inflammatories, and sometimes dietary changes. Medical options are available if symptoms are significant — discussed at consultation.

Do I need a scan?

Assessment starts with clinical examination. Imaging is added if there is a palpable finding, or if the history suggests it is needed.

Step 1 of 3

Should I be assessed?

Most common
Cyclical mastalgia

Hormonal breast pain linked to the menstrual cycle — typically bilateral, worse in the week before a period, and better afterwards. Very common and benign. Usually improves with self-management and reassurance.

Non-cyclical mastalgia

Breast pain not linked to the menstrual cycle. May come from the breast tissue itself or from surrounding structures (chest wall, ribs, or cartilage). Requires assessment to identify the cause.

Chest wall pain

Pain from the ribs, cartilage (costochondritis), or muscles — often mistaken for breast pain. Typically reproducible when pressing the chest wall; often worse on certain movements. Benign.

What happens at assessment?

Step 1
Book an assessment

Contact the practice. Note which breast, how long the pain has been present, whether it varies with your menstrual cycle, and any associated changes (lump, skin change, discharge).

Step 2
One-stop clinic visit

Clinical examination; imaging added if a palpable finding is present or the history warrants it. Most patients receive a clear diagnosis and management plan at the same visit.

Step 3
Management plan

Most breast pain is discharged with reassurance and self-management advice. Options for medical management discussed if the pain is significant. Follow-up arranged if imaging or biopsy results are pending.

Step 4
Follow-up

Return if symptoms change, a new lump develops, or the pain is worsening despite management. Annual breast awareness applies as for any patient.

What you need to know first

If the pain is mild, comes and goes with your cycle, affects both breasts, and is not accompanied by any other change — it is very likely to be cyclical mastalgia, which is benign and common. Specialist assessment is still reasonable if it is affecting your quality of life.

What breast pain might be

The commonest causes, in rough order of prevalence:

  • Cyclical mastalgia — hormonally driven, usually bilateral (both breasts), worse in the week or two before a period, better after. Very common; related to normal cyclical changes in breast tissue.
  • Non-cyclical mastalgia — pain not linked to the cycle; may be from the breast itself or from surrounding structures.
  • Chest wall pain — pain from the ribs, cartilage (costochondritis), or muscles behind or around the breast, often mistaken for breast pain. Typically reproducible on pressing the chest wall; often worse on certain movements.
  • Fibrocystic change — generalised lumpy or tender breast tissue, also hormone-related.
  • Cysts — a large or newly-formed cyst can cause a specific spot of pain.
  • Ductal or glandular problems — duct ectasia, mastitis, or (rarely) a breast abscess, especially during breastfeeding.
  • Medication-related — hormone treatments, some antidepressants, and occasionally other medications can cause breast pain.
  • Breast cancer — an uncommon but real cause. Pain alone without a lump or other finding is rarely cancer, but pain with another change is a reason to be seen.

The probability that breast pain — on its own, with no other findings — turns out to be cancer is low; figures vary by study and age, but the consistent message across major specialist guidance is that isolated breast pain is rarely the only presenting sign of cancer.

How breast pain is assessed

Breast pain is assessed the same way as any other breast symptom — using triple assessment tailored to the findings on examination:

  1. Clinical examination. Dr Tsang-Wright examines both breasts and armpits, and looks for any skin, shape, or nipple changes. Reproducing the pain by pressing on the chest wall helps distinguish breast pain from chest wall pain.
  2. Imaging. A mammogram (in women aged 40 and over) and an ultrasound are arranged where clinically indicated — for example if there is localised pain in one spot, a lump, or any other concerning finding. If the examination and history are strongly in favour of cyclical or chest wall pain, imaging may not be needed.
  3. Biopsy, where indicated. A biopsy is only done if imaging or examination shows something that needs sampling. The majority of breast-pain assessments do not require a biopsy.

If the conclusion is that no further tests are needed, that is a real answer, not a deferral — and most patients with isolated breast pain leave their appointment with that reassurance and a practical management plan.

Managing cyclical breast pain

If the diagnosis is cyclical mastalgia, management is usually conservative and includes:

  • Explanation and reassurance — cyclical breast pain is not linked to breast cancer; for many women, a clear explanation resolves symptoms or reduces distress (NICE CKS)
  • A well-fitting supportive bra, including during exercise and sometimes overnight
  • Topical NSAIDs (for example diclofenac or piroxicam gel) — the first-line pharmacological option in NICE CKS
  • Simple oral analgesia such as paracetamol if needed
  • A symptom diary to confirm the cyclical pattern
  • Review of any hormone-containing medication
  • Evening primrose oil, vitamin B6 and vitamin E are commonly tried for breast pain but are not supported by evidence and are not recommended by NICE
  • In a small number of cases, specific medical treatments (for example danazol — the only UK-licensed drug for severe cyclical mastalgia — or tamoxifen, which is used off-label under specialist supervision) — reserved for severe, life-affecting pain where conservative measures have failed. Both require careful counselling about side effects and contraception, and are discussed at a follow-up consultation

These options are discussed in more detail at the appointment, tailored to your symptoms and medical history.

What happens after the assessment

At the end of the visit you will typically be in one of these positions:

  • Reassurance and a management plan — cyclical or chest wall pain with no concerning findings; conservative measures discussed and no further tests needed.
  • Benign findings with a plan — for example a cyst or fibrocystic change; monitoring or simple treatment arranged.
  • Awaiting biopsy or imaging results — with follow-up already booked to discuss histology.
  • A finding needing onward investigation or treatment — discussed within a multidisciplinary team plan when needed.

A letter to your GP is sent after every appointment with your permission.

Common questions Frequently asked questions

Is breast pain a sign of cancer?
Usually, no. Breast pain on its own — without a lump, skin change, or other finding — is rarely the only sign of breast cancer. Pain combined with another change is a reason to be seen promptly.
Why do my breasts hurt before my period?
This is called cyclical mastalgia and is caused by normal hormonal changes in the menstrual cycle. It is common, benign, and usually settles within a few days of a period starting.
What is costochondritis and how is it different from breast pain?
Costochondritis is inflammation of the cartilage where the ribs meet the breastbone. The pain feels as if it is in the breast, but it is actually from the chest wall. Pressing on the affected cartilage typically reproduces the pain, which helps distinguish it from true breast pain.
Can my bra be causing breast pain?
Yes — a poorly fitted or unsupportive bra is a common and often overlooked contributor, especially during exercise. A proper fit is a reasonable first-line intervention for non-localised cyclical or activity-related pain.
When should I see a specialist for breast pain?
See a specialist if the pain is persistent beyond a menstrual cycle or two, is localised to one spot, is accompanied by any other breast change, is severe enough to disrupt your life, or is new after the menopause.
