MARIN COUNTY (KRON) — An encouraging new report has been released on breast cancer in Marin County.
Since 1981, when Marin had one of the highest rates in the country, the number of breast cancer cases has dropped 30 percent. It is now lower than the state average.
The Cancer Prevention Institute of California said the biggest factor in the decline may be that fewer women are using hormone therapy. The dual use of estrogen and progesterone has been linked to breast cancer in women over 50.
Other factors could be a drop in obesity and an increase in fitness among Marin women.
