Notes

Numbers are frequencies unless otherwise indicated.

* Cancers = The number of cancers diagnosed within 1 year following an examination with an abnormal interpretation (BI-RADS 4 or 5).

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 <= 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.
