Cancer screening

Cancer 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.
