In which entities is cancer considered a reportable disease based on federal law?

Cancer is considered a reportable disease based on federal law in various entities, including all states and the District of Columbia. Federal regulations mandate the reporting of cancer cases to ensure comprehensive data collection for public health purposes, which aids in cancer research, prevention, and control efforts. By including all states and the District of Columbia as reportable entities, it ensures a uniform approach to cancer surveillance across the country, facilitating the collection of vital statistics that can be used to make informed health policy decisions and allocate resources effectively to combat cancer.

It's important to note that while there are federal guidelines for cancer reporting, the specifics of how and what is reported can vary by state, as states may have additional laws or regulations guiding the details of their cancer reporting systems.
