A database of all cancers diagnosed in the US does not exist. However, the National Cancer Institute maintains a registry of all cancers diagnosed in eleven geographic areas in the US, which covers about 14 percent of the US population. This registry is called the Surveillance, Epidemiology, and End Results (SEER) Program.
As shown in the graph above, age-adjusted breast cancer incidence rates in California for the four major race/ethnic groups are very similar to those in the SEER Program.
Female breast cancer mortality rates in California are also very similar to those in the entire United States.
