Overview
Screening programs aim to detect disease early in asymptomatic populations. Modalities include mammography low dose CT and ultrasound in selected settings. Program design balances benefits harms and resources.
Breast Screening
Mammography remains the standard for breast cancer screening in many populations. Risk based approaches tailor screening intervals and modalities. Supplemental imaging may be used for high risk individuals.
Lung Screening
Low dose CT screening reduces lung cancer mortality in high risk smokers. Program implementation includes eligibility criteria and follow up protocols. Smoking cessation remains a key component of screening programs.
Quality and Outcomes
Screening programs require quality assurance and outcome monitoring. False positives and overdiagnosis are important considerations. Public education and access influence program success.
