The local health officers of two or more counties may join together as a region to apply for a Local Public Health Cancer Grant. The Department may require that two or more counties join together as a region to apply for a Local Public Health Cancer Grant if the Department determines that: It would be cost–effective to fund cancer prevention, education, screening, and treatment programs for targeted cancers on a regional basis; and It would serve the public health interests of the counties to fund cancer prevention, education, screening, and treatment programs for targeted cancers on a regional basis.
