Details

get_cervical_target_population() subsets the target population for cervical cancer screening: females aged between 25 years and 50 years

get_breast_cbe_target_population() subsets the target population for clinical breast examination: females aged between 25 years and 74 years

get_breast_mammogram_target_population() subsets the target population for breast cancer screening through mammography: females aged between 40 years to 74 years

get_colorectal_target_population() subsets the target population for colorectal cancer screening: males and females aged between 45 years to 75 years

These target populations are guided by the Kenya National Cancer Screening Guidelines 2018. The population projection for counties and the national level are calculated based on population growth 2.2% obtained from the Kenya National Bureau of Statistics. The annual targets follows the guidance of screening guidelines and for cervical cancer it is also guided by the WHO publication 'Planning and implementing cervical cancer prevention programs: A manual for managers.'
