The nature of palpable lumps is often difficult to determine clinically, but the following features should raise concern:

  • Hardness

  • Irregularity

  • Focal nodularity

  • Asymmetry with the other breast

  • Fixation to skin or muscle (assess fixation to muscle by moving the lump in the line of the pectoral muscle fibers with the patient bracing her arms against her hips)
