01Principles and purposeThe professional or clinical skill and the decisions it supports.

NICE breast referral criteria attach different age rules to different findings. An unexplained breast lump qualifies for the suspected-cancer pathway from age 30 whether painful or painless. Unilateral discharge, retraction or another concerning nipple change qualifies from age 50. Skin changes suggesting breast cancer have no age threshold, whereas the unexplained axillary-lump criterion applies from age 30.

Criteria standardise entry to assessment; they do not diagnose cancer or remove clinical judgement. An unexplained lump under 30 prompts consideration of non-urgent referral, while rapid progression, inflammatory change or another concerning phenotype may justify urgent specialist discussion. A safe referral names the actual finding, includes a reproducible examination, communicates uncertainty accurately and is tracked until receipt and appointment are confirmed.

Key points

  • Refer through the suspected-cancer pathway when a person aged 30 or over has an unexplained breast lump, whether painful or painless.
  • Refer a person aged 50 or over for unilateral nipple discharge, retraction or another concerning nipple change under the NICE breast recommendation.
  • Consider the suspected-cancer pathway at any age for skin changes suggesting breast cancer; NG12 does not attach an age threshold to this indication.
  • Consider the suspected-cancer pathway for an unexplained axillary lump in someone aged 30 or over.
  • For an unexplained breast lump under age 30, NICE says consider non-urgent referral, while clinical concern can justify specialist advice or greater urgency.
  • Describe the actual symptom and examination accurately, track referral acceptance and safety-net rapid growth, inflammatory change or deterioration while the person waits.
02Situations and prioritiesThe context, relevant information and actions that matter most.
Unexplained lump from age thirty

NICE recommends a suspected-cancer pathway referral for people aged 30 or over with an unexplained breast lump, whether or not the lump is painful.

Concerning nipple change from age fifty

For people aged 50 or over, unilateral nipple discharge, retraction or another concerning nipple change meets the NICE suspected-cancer pathway criterion.

Suspicious skin change has no age threshold

Skin changes that suggest breast cancer should prompt consideration of a suspected-cancer pathway referral at any age; the recommendation does not specify an age cutoff.

Unexplained axillary lump from age thirty

An unexplained axillary lump in a person aged 30 or over should prompt consideration of the suspected-cancer pathway after focused breast and nodal examination.

Thresholds do not replace judgement

A person under 30 with an unexplained breast lump is considered for non-urgent referral in NG12, but rapid progression, inflammation or other concerning features can justify urgent specialist discussion.

03Assessment and interpretationHow to gather information, assess the situation and recognise uncertainty.
Reasoning sequence

Consider the information, its meaning and its limitations before deciding what follows.

  1. 01
    Focused referral history
    Why
    Establish whether the feature is unexplained and matches a current criterion.
    Interpretation and limitations
    Record age, duration, laterality, pain, nipple and skin changes, pregnancy or lactation, infection features and prior imaging so triage can understand the concern.
  2. 02
    Clinical breast and nodal examination
    Why
    Provide objective findings while avoiding false reassurance from absence of a classic mass.
    Interpretation and limitations
    Map a lump, describe tethering and examine axillary and supraclavicular nodes; suspected inflammatory cancer may present with diffuse skin change rather than a discrete lump.
  3. 03
    NICE criterion check
    Why
    Match the observed feature to the exact recommendation and urgency.
    Interpretation and limitations
    Do not alter the patient’s age, duration or finding to fit a pathway; if concern remains outside criteria, seek specialist advice and document clinical reasoning.
  4. 04
    Referral tracking and safety net
    Why
    Confirm the pathway has accepted the referral and the patient knows what happens next.
    Interpretation and limitations
    Explain that referral investigates a possibility rather than confirming cancer, and provide a contact route if symptoms progress or an appointment is not received.
04Worked approachesCases with ordered reasoning, an action and a check of the outcome.
01Worked case: integrated breast assessmentApply urgent suspected breast-cancer referral to a defined presentationA 33-year-old presents with a new unexplained painless breast lump. They ask whether lack of pain means it can safely be reviewed after several months.
  1. 1Take a targeted history and examine the breasts and nodes, documenting the lump site and any skin, nipple or systemic features that could affect triage.
  2. 2Match the case to NG12: age 30 or over with an unexplained breast lump qualifies for a suspected-cancer pathway referral with or without pain.
  3. 3Explain the referral in neutral terms, including that most assessed symptoms are not cancer but timely triple assessment is needed to establish the diagnosis.
  4. 4Send a complete referral containing relevant history, examination, accessibility and communication needs, and provide written information about the expected process.
  5. 5Verify electronic acceptance and appointment arrangements; safety-net rapid growth, new erythema, skin distortion, nipple bleeding or systemic deterioration.
02Criterion applicationMatch the person to the exact NICE wordingA breast symptom requires a referral decision in primary or urgent care.
  1. 1Determine age, whether a lump or axillary finding is unexplained, and whether nipple or skin change is unilateral, new and concerning.
  2. 2Apply the recommendation without inventing exclusions: pain does not remove the age-30 unexplained-lump criterion, and absent family history does not cancel it.
  3. 3If the automatic wording is not met but the phenotype remains concerning, use clinical judgement and specialist discussion rather than falsely documenting a criterion.
  4. 4Tell the person the urgency, likely clinic process and expected communication route, then send a complete examination-based referral.
03Referral reliabilityMake sure an urgent decision becomes careThe electronic suspected-cancer referral has been submitted but no appointment is visible after the expected administrative interval.
  1. 1Check transmission, required attachments and whether triage accepted or returned the referral; do not assume submission equals receipt.
  2. 2Contact the receiving service to resolve rejected information and document the named team member who now owns triage.
  3. 3Update the patient honestly, confirm current symptoms and escalate clinically if a mass grows or new skin, nipple or systemic features develop.
  4. 4Record the final appointment or alternative plan and ensure language, disability, transport or caring needs have been communicated.
05Feedback, follow-up and evidenceReview outcomes, seek feedback and identify what to improve.
  • Maintain a referral tracker showing submission, acceptance, appointment and outcome for every suspected-cancer pathway request.
  • If triage asks for more information, supply a lesion map and associated skin, nipple or nodal findings without allowing administrative exchange to reset clinical urgency.
  • Reassess sooner when symptoms progress during the wait; a new inflammatory pattern or systemic illness may require same-day care as well as cancer referral.
  • After clinic assessment, reconcile the result with the original presentation and re-refer or discuss if the unexplained finding persists despite an apparently benign report.
06Special situationsVariants, exceptions and circumstances that change the usual approach.

Criteria are entry points

NG12 thresholds standardise access but do not contain every dangerous presentation. Clinical judgement remains necessary for rapid progression, inflammatory change and patients just below an age threshold.

Pain is explicitly included

For an unexplained lump from age 30, the recommendation says with or without pain. Treating tenderness as reassurance contradicts the criterion.

Language should be accurate

Say the pathway is designed to exclude or diagnose cancer promptly. Telling a person they probably have cancer before assessment creates avoidable harm.

Safety net the system as well as symptoms

Patients need to know what to do if no appointment arrives. Services also need active tracking so a technical rejection is not mistaken for completed care.

07Common pitfallsFrequent interpretation and management errors.
  1. 01

    Delaying an unexplained lump because it is tender misreads the explicit with-or-without-pain wording in NG12.

  2. 02

    Changing the recorded age or examination to force an electronic criterion undermines safe triage and clinical records.

  3. 03

    Sending a two-word breast lump referral without coordinates or associated findings prevents informed urgency assessment.

  4. 04

    Assuming that an electronic submission automatically produced an appointment leaves patients vulnerable to rejected or lost referrals.
