Screening programs involve testing asymptomatic individuals with an accurate screening test to identify those likely to have the disease of interest and to further investigate them to confirm or exclude the disease. The aim of cancer screening is to prevent cancer deaths and improve quality of life by finding cancers early and by effectively treating them. A decision to introduce a screening program in public health services depends on the evidence that the benefits outweigh the harms of screening, disease burden, availability of suitable screening test, effective treatment, adequate resources, and efficient health services. Screening programs should achieve high participation for testing, diagnosis, and treatment to be effective and efficient. ⋯ Implementation of VIA screening in several LMICs is conducive to future HPV screening programs when affordable HPV tests become widely available. Both HPV vaccination and HPV screening have a huge potential to eliminate cervical cancer in LMICs. A mammography screening program is a complex undertaking involving substantial resources and infrastructure that may not be feasible in many LMICs.

ReviewInfection and cancer: global distribution and burden of diseases.
Infection is one of the main risk factors for cancer. ⋯ Widespread application of existing public health methods for the prevention of infection, such as vaccination, safer injection practices, quality-assured screening of all donated blood and blood components, antimicrobial treatments, and safer sex practices, including minimizing one's lifetime number of sexual partners and condom use, could have a substantial effect on the future burden of cancer worldwide.
