What is cancer screening and why is it important?

Cancer screening refers to tests that can help find cancer before symptoms appear. Early detection is crucial because it can lead to better treatment outcomes. For example, breast cancer, cervical cancer, and colorectal cancer can be detected early through screening programs provided by the NHS. In the UK, these screenings are offered to specific age groups, ensuring that those at higher risk are monitored closely. Participating in these screenings is vital, especially for high-risk groups, as it can significantly improve the chances of successful treatment.
