Our Catchment Area
UC Davis Comprehensive Cancer Center’s “catchment area,” the area it serves, is comprised of 19 counties that cover 23,800 square miles (approximately the size of West Virginia). Of these counties, eight are considered rural. According to the 2020 Census, the region has 5,165,758 residents, an increase of 10.74% since 2010. In total, 90% of our cancer center patients reside in this large region. The Cancer Center’s catchment area is one of the most geographically and ethnically diverse in the nation, which creates opportunities to engage with many people in a meaningful and impactful way. The catchment area also accounts for 28% of California’s total land in farming (i.e., cropland, pastureland, woodland). In fact, three of the counties in the catchment area are among California’s top ten agricultural counties (Stanislaus, Merced, and San Joaquin).

Factors That Impact Cancer Risk
Risks associated with a person’s chances of developing cancer include genetic, behavioral, environmental, and socioeconomic factors. While genetics are not considered modiļ¬able, the other factors below can be influenced by behaviors.
Food insecurity: Food insecurity is a household-level economic and social condition of limited or uncertain access to adequate food.

Poverty among all individuals: Poverty is the state of one who lacks the means to basic needs. Those living below the national poverty line of $12,880 a year for a single individual are considered to be living in poverty.

Pesticides: Pesticides are chemicals used to control insects, weeds and plant diseases. Over 1,000 pesticides are registered for use in California. They are applied to fields by air, by farm machinery, or by workers on the ground. Farmworker families and other people who live near fields can be exposed to pesticides, both outdoors and inside homes. Exposure to high levels of some pesticides can cause illness right away or conditions such as birth defects or cancer later in life.

It is important to note cancer screening rates reflect both highly urban and rural areas. The lower cancer screening rates may be attributable to potential barriers rural areas could be facing with regard to screening efforts. All individuals eligible for screening should get their appropriate screenings to prevent cancer and reduce the cancer burden.
*The target percentage for 2020 was included to emphasize the ongoing need for improvement in both the catchment area and California as a whole, as outlined by the goals in California's Comprehensive Control Plan for 2021-2025 prepared by the California Dialogue on Cancer and supported by CDC data.
Mammography screening: Mammography screening is an x-ray picture of the breast to check for breast cancer in women who have no signs or symptoms of the disease.
