Breast lesion localisation (mnemonic)

A mnemonic to help remember breast lesion localisation when given a set of mammograms (MLO and CC) is:

  • muffins rise and lead falls

This can help localise the lesion into the quadrant (e.g. upper, outer) to make ultrasound correlation easier.


  • muffins rise: if the lesion is located medially it will be in a higher position (provided that the lesion is at the upper inner quadrant)
  • lead falls: if the lesion is located laterally, it will be in a lower position (provided that the lesion is at the lower outer quadrant)

For example, if a lesion projects at the level of the nipple on MLO of the right breast and it is medial it will be at around the 2 o'clock position, whereas if it were lateral it would be at the 8 o'clock position.
