By 1998 the NHS breast screening programme had directly produced a reduction in annual mortality from breast cancer of 6-7% in women aged 55-69, although the sensitivity analysis indicated a probable range of 5-12%.ubjects: Women aged 40 to 79 years. Results: Compared with predicted mortality in the absence of screening or other effects the total reduction in mortality from breast cancer in 1998 in women aged 55-69 was estimated as 21.3%.
