Cancer Screening & Diagnosis

Cancer screening to detect before symptoms appear. This involve blood tests, urine tests, DNA tests other tests, or medical imaging. The benefits of screening terms of cancer prevention, early detection and subsequent treatment must be weighed against any harm. Since screening diseases find at an early stage, there may be a better chance of curing the disease. Examples of cancer screening tests are the mammogram for breast cancer, colonoscopy for colon cancer, and the Pap test and HPV tests for cervical cancer. Screening can also include a genetic test to check for a person’s risk of developing an inherited disease.

Screening tests must be effectively, safe, well-tolerated with acceptably low rates of false positive and false negative results. If cancer is detected, more definitive and invasive follow-up tests are performed to reach a diagnosis. Screening can lead to cancer prevention and earlier diagnosis. Early diagnostics may lead to higher rates of successful treatment and extended life. However, it may also appear to increase the time to death through lead time bias or length time bias.
