Cancer Data and Statistics for the General Public

The Greater Bay Area Cancer Registry provides cancer data and statistics in a variety of forms, and works closely with our partners at the California Cancer Registry and the National Cancer Institute to provide a number of reports, publications, and online interactive tools to help you get the cancer statistics you are interested in.  Below we provide a number of products and links, but if you still can’t find what you are looking for, feel free to contact the Data Release Coordinator at (510) 608-5022 or

    Custom Tabulated Data

    If you are interested in cancer data that you cannot find in published reports (like those listed above), here are two ways to obtain it:
    1) through interactive websites that allow you to specify, calculate and display the data you want (see below); or
    2) by submitting a data request to us

    Community Cancer Concerns

    One of the most common types of data requests stems from a concern that there may be an excess of cancer in a community (sometimes called a "community cancer concern" or a possible "cancer cluster"). As part of the state-mandated cancer registry, the GBACR has the responsibility to respond to these requests from the public for the Greater Bay Area.  

    The GBACR responds to these concerns through a combination of education, information, and statistical analysis. Although the occurrence of cancer may seem high in an area, people are often unaware of how common cancer is in the United States. Current statistics show that approximately 1 in 2 Americans will develop some form of cancer during his or her lifetime. In addition, cancer is not just one disease, but in fact, many different diseases caused by a wide variety of environmental and non-environmental factors.  For example, the factors that cause breast cancer are very different from the factors that cause colorectal cancer. And, for many types of cancer, there are no known causes.

    "Cancer clusters" can and usually do occur by chance alone. If a computer randomly assigns 100 dots to a grid with 100 squares, some squares will have several dots and some will have no dots by chance alone. In the same way, many cancer clusters are groupings of cancer cases in time and geographic area due to chance alone. Therefore, we conduct statistical analyses when appropriate to determine if a significantly higher number of cancer cases occurring within a geographic location can be explained by chance, or if this excess number of cases is occurring merely by chance.

    For more information about community cancer concerns, please download our document Cancer Cluster Investigation in the Greater Bay Area and visit the California Cancer Registry website's section on this topic here.
