Cancer Screening
It is an attempt to detect unsuspected cancers in an asymptomatic population. Screening tests suitable for large numbers of healthy people must be relatively affordable, safe, noninvasive procedures with acceptably low rates of false positive results. If signs of cancer are detected, more definitive and invasive follow up tests are performed to confirm the diagnosis. Screening for cancer can lead to earlier diagnosis in specific cases. Early diagnosis may lead to extended life, but may also falsely prolong the lead time to death through lead time bias or length time bias. A number of different screening tests have been developed for different malignancies, some of tests are:

• Breast cancer screening (by breast self-examination).
• Colorectal cancer can be detected through fecal occult blood testing and colonoscopy.
• Testicular self-examination is recommended for men beginning at the age of 15 years to detect testicular cancer.
• Cervical cancer screening via the Pap smear.
