Table 3 Excess relative risks of incidence of and mortality from breast cancer in 1992–2002, and of incidence-based mortality in 1992–2002 in comparison with the baseline without screening by age. The baseline without screening was estimated by models using information from time before screening and in age groups not subjected for service screening (40–49; and 65–69 up to the year 1991, see the text).

  1. A Age at diagnosis was used for the estimates for BC incidence and incidence-based mortality; age at death was used for the BC mortality.
  2. B Includes ages 60–64 at diagnosis. Excess relative risk is not available for age group 65–69 since for them the steady state started in 1997.
  3. C Includes ages 50–64 at diagnosis.
