Breast Cancer Incidence in Cape Cod towns 1993 - 1997

Between 1993 and 1997, 9 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 6 of these towns.

For the period 1982 - 1994, 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.
