Table 6.

Using breast cancer incidence for 2006 [from the National Program of Cancer Registries (Ref. ²¹)] and assuming 25% women have dense breast tissue, with fivefold increase in risk of breast cancer, the table shows estimated cancer incidence in a population of 100 000 women with dense breasts. The mortality rate (M_t) was assumed to be the same as in Table 5. All numbers are cumulative to age 80 for 100 000 females.

Age range	Breast cancer incidence	Estimated breast cancer mortality w∕o screening
0–80	31 300
40–50	3 735	523
50–60	6 110	1138
60–80	19 108	5866
