Non-communicable diseases such as cancer and cardiovascular diseases are leading causes of death globally. Cancer screening programs aim to detect cancers early when they are more likely to be cured. Screening tests for common cancers include pap smears for cervical cancer, mammography for breast cancer, and low-dose CT scans for lung cancer. Managing risk factors such as smoking, diet, exercise, and treating conditions like diabetes and hypertension can help prevent cancer and cardiovascular diseases.
