Notes

Numbers are frequencies unless otherwise indicated.

^* Cancers = The number of cancers diagnosed within 1 year following an examination with an abnormal final interpretation. (BI-RADS category 4 or 5; Note: 0 or 3 with a recommendation for biopsy was recoded as 4).

^† Numbers in parentheses are percentages of all cancers.

^‡ Numbers in parentheses are percentages of invasive cancers of known size.

^§ Minimal cancer = DCIS or invasive cancer 1-10 mm; numbers in parentheses are percentages of DCIS + invasive cancer of known size.

^|| Numbers in parentheses are percentages of invasive cancers of known nodal status.

^# Numbers in parentheses are percentages of DCIS + invasive cancers of known stage.

^{^} Numbers in parentheses are percentages of DCIS + invasive cancers of known grade.
