Screening for Cancers by RUTH SAKALA - Oncology-unza

Description

This oncology presentation provides a comprehensive overview of cancer screening as a secondary prevention strategy, detailing its principles, ideal test characteristics, and specific applications for common malignancies. The material explains the rationale for screening, including early detection of asymptomatic cancers to reduce morbidity and mortality, and outlines the attributes of an ideal screening test: cost-effectiveness, specificity, sensitivity, accessibility, safety, and acceptability. Key screenable cancers are covered, with recommended methods and intervals for breast cancer (mammography, ultrasound, MRI), lung cancer (low-dose CT for high-risk individuals), cervical cancer (Pap smear, HPV testing), colorectal cancer (fecal occult blood tests, colonoscopy), and prostate cancer (PSA, digital rectal exam). The presentation also addresses biases in screening, such as volunteer and lead-time biases, and pitfalls like false positives and overdiagnosis. This resource is essential for medical students, oncology trainees, and practitioners in Zambia, offering structured, exam-focused content for understanding cancer screening protocols within a tertiary medical education framework.
