Breast symptoms in general practice
Also known as Breast lump · Mastalgia · Nipple discharge · Triple assessment
GP-fellowship guide to breast symptoms: the triple assessment and its measured accuracy, sorting lumps by age and findings, mastalgia management with the evidence against evening primrose oil, nipple discharge and papilloma upgrade rates, breast abscess drainage, the benign-diagnosis reassurance gap, and the referral rules that keep cancer detection safe.

Red flags
- A discrete lump in a woman over 30 is cancer until triple assessment proves otherwise — clinical benignity alone never discharges the referral
- Peau d'orange, skin tethering, nipple retraction or new nipple inversion is a cancer pathway referral regardless of the palpability of any lump
- Mastitis that fails to respond to a completed antibiotic course, especially in a non-lactating woman or smoker, needs imaging and biopsy — inflammatory cancer mimics mastitis
- A painless, progressively enlarging firm lump in a woman over 40 suggests a phyllodes tumour — refer; these are undersampled on core biopsy and excised, not observed
- Blood-stained single-duct nipple discharge in a woman over 40 requires imaging and biopsy — intraductal papilloma carries a 21% upgrade to DCIS when atypia is present
Overview
Breast symptoms are among the commonest reasons women present to general practice, and the presenting symptom is almost always fear. The four presentations are a lump, breast pain (mastalgia), nipple discharge, and skin or nipple change. Benign disease dominates the caseload — in a consecutive series of 100 women with breast complaints, fibroadenoma accounted for 59%, fibroadenosis 19% and breast abscess 16% — but the consultation exists because cancer must be excluded, and the exclusion must be structured.[22]
The structure is triple assessment: clinical examination, imaging, and tissue sampling, read together. Combined, the three components reach sensitivity of 99–100% with specificity around 99% across series.[9][6] The GP's role is not to complete the triple assessment — imaging and biopsy are specialist-provided — but to recognise which symptoms need it, start it through the right pathway, and manage the large benign majority with evidence rather than reflex.[15]
