The Los Angeles County Cancer Surveillance Program collects and analyzes information on all new cancer diagnoses made among residents of the County. It is an example of a:

The Los Angeles County Cancer Surveillance Program serves as a population-based central cancer registry because it systematically collects data on all new cancer diagnoses among residents within a specific geographic area, in this case, Los Angeles County. This type of registry aims to provide a comprehensive overview of cancer incidence within the population, facilitating research, public health initiatives, and resource allocation.

Population-based registries are essential for tracking cancer trends over time, assessing the effectiveness of cancer control efforts, and ensuring that healthcare providers are informed about the cancer burden in their communities. By focusing on all individuals diagnosed with cancer in the county, the program underscores the importance of inclusive data collection, which is a hallmark characteristic of population-based registries.

In contrast, a facility-based cancer registry would collect data from a specific healthcare facility rather than across a broader community. Similarly, a non-population-based central cancer registry would not aim to represent the entire population but rather focus on selected data points, which does not apply to the Los Angeles County Cancer Surveillance Program. A specialty registry usually targets specific types of cancer or particular patient populations, differentiating it from the broad approach of a population-based registry. Thus, the selected answer accurately reflects the nature of the program in question.
