Breast Cancer Incidence in Cape Cod towns, 1994 - 1998

Between 1994 and 1998, 11 of the 15 towns on Cape Cod had breast cancer incidence rates at least 15 percent higher than those found in the rest of Massachusetts. Elevated incidence was statistically significant in 7 of these towns. The map below shows the Cape's townships, indicates their standardized incidence ratios (in parentheses), and shows whether their incidence rates are statistically significant.

We also looked at breast cancer incidence on Cape Cod in geographic units smaller than towns. In order to discern whether breast cancer incidence varied within towns or across town boundaries, we looked at breast cancer in census tracts and census block groups.
