Breast Cancer Rates Plummet in Marin County

The number of women diagnosed with breast cancer in Marin County has fallen to its lowest level, according to a new study from the Cancer Prevention Institute. Marin, which once suffered some of the highest breast cancer rates in the world, is now in line with the California State average.

According to the study, the county has seen a 31 percent drop in new diagnoses since 2001. Over the past 27 years, breast cancer deaths have also declined by 65 percent.

Despite Marin’s reputation as one of the healthiest places in the nation, it has long suffered from an abnormally high breast cancer rate. The reason is believed to be a combination of factors, including the prevalence of hormone replacement therapies and delayed childbearing.

The latest study seems to bear out the hormone replacement theory because the sharp drop in cancer rates was accompanied by a steep reduction in the use of hormone therapy. Still, experts say factors like good nutrition, exercise and a lower obesity rate have probably also played a role.
