Cancer screening

Cancer Screening is a preventive healthcare approach aimed at detecting cancer or precancerous conditions in individuals who do not yet show symptoms. Early detection through screening significantly improves treatment outcomes, survival rates, and quality of life. Common cancer screening methods include mammography for breast cancer, Pap smear and HPV testing for cervical cancer, colonoscopy and fecal tests for colorectal cancer, low-dose CT for lung cancer, and PSA testing for prostate cancer. Screening programs are often targeted based on age, gender, risk factors, and family history. From a public health perspective, organized population-based screening helps reduce cancer-related mortality and healthcare costs. However, effective screening requires evidence-based guidelines, quality assurance, informed consent, and access to follow-up care. Education and awareness are essential to increase participation and address disparities. Cancer screening remains a cornerstone of cancer prevention and early diagnosis strategies worldwide.
