*
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.
