Cancer screening
hideCancer screening occurs for many type of cancer including breast, prostate, lung, and colorectal cancer. Cancer screening 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.[citation needed]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.[citation needed]
