Synopsis
Develop the ability to take a focused history, examine both breasts and nodal basins respectfully, and translate findings into an urgent, concordant diagnostic plan, while explaining uncertainty and arranging reliable review.
- Ask when the lump appeared, whether it is enlarging or cyclic, and whether pain, nipple change, skin distortion, fever or systemic symptoms accompany it.
- Record pregnancy, lactation, menopause, previous breast disease, chest irradiation, hormone exposure, anticoagulants and relevant breast, ovarian, pancreatic or prostate cancers in the family.
- Inspect both breasts with changing arm positions, then palpate systematically and map the lump by side, clock face, nipple distance, size, consistency, mobility and fixation.
Reasoning priorities
Define the palpable target and search for associated signs before imaging.
Describe side, clock position, distance from nipple, size, surface, consistency, mobility, skin or chest-wall fixation, and axillary or supraclavicular nodes; examination cannot determine histology.
Worked reasoning
A 46-year-old notices a firm left upper-outer breast lump six weeks ago; it is enlarging, and there is subtle dimpling when she raises her arm but no fever.
- Clarify duration, progression, pain, nipple and systemic symptoms, reproductive and treatment history, then ask about relevant cancers on both sides of the family.
- Offer a chaperone and obtain continuing consent; inspect both breasts in several arm positions, palpate systematically, map the lesion and assess axillary and supraclavicular nodes.
- State that a new enlarging lump with tethering is clinically suspicious and arrange the appropriate suspected-cancer pathway rather than offering empirical treatment.
- At the breast service, correlate examination with imaging and image-guided tissue diagnosis; do not call the assessment complete if one component conflicts with the others.
- Verify referral receipt, tell the patient how results will be communicated, and safety-net earlier review for rapid enlargement, erythema or systemic illness.
