The Cardiff breast pain chart and the nominal days with severe pain (NDSP) can be used to monitor breast pain and its response to any interventions.

Carduff breast pain chart is a calendar for recording factors of breast pain:

(1) days with period

(2) days with mild to moderate breast pain

(3) days with severe breast pain

(4) days with no pain


nominal days with severe breast pain = NDSP =

= ((0.5 * (days with mild to moderate pain)) + (days with severe pain)) / (total number of days in cylce) * 28


total number of days in cycle =

= (days with mild to moderate pain) + (days with severe pain) + (days with no pain)



• Multiplying by 28 adjusts raw value to a standard 28 day cycle.
