breast mass AND diagnosis
breast lumps differential diagnosis clinical assessment guideline American Cancer Society
| Differential diagnosis | Typical age/pattern | Key clinical clues | Features that raise concern |
|---|---|---|---|
| Invasive breast carcinoma | More common after menopause | Usually a single hard, irregular, poorly mobile mass; may be painless or painful | Fixity to skin/chest wall, skin dimpling or peau d’orange, nipple retraction, bloody discharge, axillary nodes, weight loss |
| Ductal carcinoma in situ (DCIS) | Usually detected on screening, sometimes presents with discharge or lump | Often non-palpable; may have nipple discharge or associated invasive focus | Suspicious calcifications on mammography; needs tissue diagnosis |
| Breast cyst | Common around 35-50 years, less common after menopause unless on HRT | Smooth, round, mobile lump; may be tender and fluctuate | New cystic lesion after menopause requires imaging to exclude a complex cystic-solid lesion |
| Fibroadenoma | Usually adolescents and younger women | Firm, rubbery, well-circumscribed, very mobile "breast mouse" | New fibroadenoma-like mass in an older woman should not be assumed benign |
| Phyllodes tumor | Usually 40-60 years | Painless, mobile, well-defined mass that may grow rapidly and become large | Rapid enlargement, large size, stretched skin; diagnosis requires core biopsy/excision |
| Fibrocystic change / nodularity | Premenopausal, may persist near menopause | Diffuse nodularity, breast heaviness and tenderness, often cyclic | A dominant persistent lump must be evaluated separately from generalized nodularity |
| Duct ectasia | Perimenopausal or older women | Subareolar lump, thick green/brown nipple discharge, nipple retraction may occur | Can mimic cancer clinically, especially with a new nipple retraction |
| Intraductal papilloma | Usually 35-55 years | Small subareolar lesion, classically spontaneous unilateral bloody or serous nipple discharge | Bloody discharge requires imaging and pathological assessment |
| Mastitis / breast abscess | Common during lactation but can occur otherwise | Painful, warm, red, tender lump; fever may occur; abscess may feel fluctuant | Non-lactational mastitis in an older patient or failure to improve may represent inflammatory carcinoma |
| Fat necrosis | After trauma, surgery, radiotherapy, or anticoagulation | Firm irregular lump, may cause skin tethering or bruising | May closely resemble carcinoma on examination and imaging |
| Lipoma / hamartoma | Any age | Soft, lobulated, mobile, usually painless | Usually benign, but a new enlarging lesion still requires imaging |
| Galactocele | Pregnancy or breastfeeding | Painless or mildly tender, cystic mass related to lactation | Unusual in a 70-year-old woman |
| Breast lymphoma or metastasis | Older age or prior malignancy | Rapidly enlarging mass, sometimes multiple, with or without nodes | Prior cancer, systemic symptoms, rapid growth |
