Js. Goodwin et al., GEOGRAPHIC VARIATIONS IN BREAST-CANCER MORTALITY - DO HIGHER RATES IMPLY ELEVATED INCIDENCE OR POORER SURVIVAL, American journal of public health, 88(3), 1998, pp. 458-460
Objectives. Mortality rates from breast cancer are approximately 25% h
igher for women in the northeastern United States than for women in th
e South or West. This study examined the hypothesis that the elevation
is due to decreased survival rather than increased incidence. Methods
. Data on breast cancer incidence, treatment, and mortality were revie
wed. Results. The elevated mortality in the Northeast is apparent only
in older women. For women aged 65 years and older, breast cancer mort
ality is 26% higher in New England than in the South, while incidence
is only 3% higher. Breast cancer mortality for older women by state co
rrelates poorly with incidence (r = 0.28). Conclusions. Those seeking
to explain the excess breast cancer mortality in the Northeast should
assess survival and should examine differences in cancer control pract
ices that affect survival.
