Breast cancer in New South Wales in 1972-1995 : Tumor size and the impact of mammographic screening.
To examine the use of mammographic screening in women in New South Wales (NSW), we measured uptake of initial mammograms and estimated the proportions of breast cancers that were screen detected.
To see if mammographic screening has been associated with reductions in advanced breast cancers and mortality from breast cancer, we analyzed trends in age-specific and age-standardized breast cancer incidence and mortality from 1972 to 1995 and tumor size in 1986,1989,1992 and April to September 1995.
Between 1984 and the end of 1995, an estimated 72% of NSW women in their 50s and 67% in their 60s had had at least I mammogram and, in 1995, an estimated 39% of invasive breast cancers in women in these age groups were detected by mammography.
Before 1989, breast cancer incidence increased only slightly (+1.3% annually) but then, from 1990 to 1995, increased more rapidly (+3.1% annually).
Between 1986 and 1995, rates of small cancers (
The incidence of large breast cancers (3+cm), after little apparent change to 1992, fell by 17% in women 40-49 years of age and 20% in those 50-69 years of age to 1995.
Breast cancer mortality increased slightly between 1972 and 1989 (+0.5% annually) but then fell (-2.3% annually) from 1990 to 1995. (...)
