Quick answer
Cyclical breast pain is hormonal: it affects both breasts, is worst in the week or so before a period, eases when bleeding starts, and is felt as diffuse heaviness. Non-cyclical pain has no relationship to the cycle, is more often one-sided and pinpointed, and frequently originates in the chest wall rather than the breast.
Key takeaways
- Keeping a simple pain diary across two cycles distinguishes the two types more reliably than any test.
- Cyclical pain is the commonest form, is not associated with an increased risk of breast cancer, and usually responds to a properly fitted bra and simple measures.
- Non-cyclical pain that is sharply localised and reproduced by pressing the ribs is usually musculoskeletal, not breast tissue at all.
- Breast pain on its own is an uncommon way for breast cancer to present, which is why pain alone is not a suspected cancer referral criterion in NICE NG12.
- Pain plus a lump, skin change or nipple change is a different situation and needs assessment.
- Medication is a frequently missed cause: HRT, hormonal contraception and some antidepressants can all produce breast tenderness.
Breast pain is the single most common breast symptom people present with, and the great majority of it turns out to be either hormonal or coming from the chest wall behind the breast rather than from breast tissue. Neither of those is dangerous. Both are treatable. And the way to tell them apart costs nothing: write down when it hurts.
What is cyclical breast pain?
Cyclical mastalgia is breast pain driven by the hormonal changes of the menstrual cycle. It has a recognisable signature. It affects both breasts, though often unequally. It is felt as heaviness, fullness or a dull ache rather than a sharp point of pain, and it is usually worst in the upper outer part of the breast, sometimes radiating into the armpit. It builds through the second half of the cycle, peaks in the few days before a period, and settles once bleeding starts.
It is common, it is not a disease, and it carries no increased risk of breast cancer. It tends to be worse in the years approaching the menopause, when cycles become erratic, and it usually resolves after it.
What is non-cyclical breast pain?
Non-cyclical pain has no relationship to the cycle. It is more often on one side, more often described as sharp, burning or stabbing, and more often localised to a spot the patient can put a fingertip on. That last feature is the most useful one, because true breast tissue pain is rarely that precise.
The commonest source is the chest wall. Costochondritis, inflammation where the ribs meet the breastbone, produces exactly this pattern, and it can be reproduced by pressing on the rib rather than the breast. Muscular strain, referred pain from the neck or upper spine, and shingles before the rash appears all present similarly. Within the breast itself, duct ectasia, a cyst under tension and mastitis can all cause non-cyclical pain.
Medication deserves its own mention because it is so often overlooked. HRT, combined hormonal contraception, some antidepressants and some anti-sickness drugs can all cause breast tenderness, and the timing of when the pain started relative to a new prescription is worth checking before anything else.
How can I tell which type I have?
A pain diary over two cycles. Mark the days you have pain, how bad it is out of ten, and the first day of each period. If the pain clusters in the ten days before bleeding and fades afterwards, it is cyclical. If it is scattered with no pattern, it is not. This is genuinely more informative than imaging in someone with pain and nothing else, because imaging cannot see pain.
| Feature | Cyclical | Non-cyclical |
|---|---|---|
| Timing | Worst in the week before a period, eases with bleeding | No relationship to the cycle |
| Sides | Both breasts, often unequally | Usually one breast |
| Character | Heavy, full, dull ache | Sharp, burning or stabbing |
| Location | Diffuse, often upper outer quadrant, may radiate to the armpit | Localised, often to a point you can cover with a fingertip |
| Reproduced by pressing the ribs | No | Often yes, which points to the chest wall |
| Typical age | Late twenties to the menopause | Any age, more common after 40 |
| Usual cause | Hormonal response of normal breast tissue | Chest wall, muscle, referred spinal pain, duct change or medication |
| First-line management | Well-fitted supportive bra, simple analgesia, medication review | Treat the source: topical anti-inflammatory for chest wall, address posture or medication |
“When someone can put one finger on the spot and it hurts when I press the rib rather than the breast, we are usually not talking about a breast problem at all. That reframing is a relief to most people.”
Mr Debashis Ghosh, Consultant Breast and Oncoplastic Surgeon
Pain with a lump, a skin change or nipple discharge is a different situation from pain alone. Our breast pain and nipple discharge service assesses both, and the same-day one-stop breast clinic brings examination, imaging and results into a single visit. We also see our clinic for Hampstead patients.
Breast pain: frequently asked questions
Is breast pain a sign of breast cancer?
Rarely on its own. Breast pain is an uncommon presenting symptom of breast cancer, which is why NICE NG12 does not include pain alone among its suspected cancer referral criteria. Pain accompanied by a lump, a skin change or a nipple change is a different matter and should be assessed.
What actually helps cyclical breast pain?
A properly fitted supportive bra makes more difference than most people expect, particularly for exercise and sleep. Simple analgesia, a topical anti-inflammatory gel, and reviewing any hormonal medication with your GP are the next steps. Severe pain that does not respond can be treated with prescribed hormonal medication under specialist supervision.
Does cutting out caffeine help breast pain?
The evidence is weak. Some women report improvement and there is no harm in a trial for a couple of months, but it should not be relied on in place of a well-fitted bra and a medication review, which have more to offer.
Can HRT cause breast pain?
Yes, and it is one of the more common causes of new breast tenderness in women over 45. It is often worst in the first few months and settles. If it persists, the dose or preparation can usually be adjusted, so it is worth raising with whoever prescribes it.
I have pain in one spot that hurts when I press it. What is that?
Sharply localised pain that is reproduced by pressing on the rib rather than the breast is most often costochondritis or another chest wall cause. It typically responds to a topical anti-inflammatory and time, though it can take several weeks.
Should I have a scan for breast pain?
Not automatically. In someone with pain and no other finding, imaging usually adds little, and a careful examination plus a pain diary is more informative. Imaging becomes appropriate if there is a lump, a persistent focal abnormality, or if you are in an age group where a baseline mammogram is due anyway.
When should I be worried enough to get breast pain checked?
If the pain is persistent, always in the same spot, associated with a lump, skin change or nipple discharge, or if you simply cannot settle without knowing. Anxiety about a symptom is a legitimate reason to have it assessed, and being examined and reassured is a reasonable outcome to want.
