American Cancer Society Cancer Prevention and Early Detection Guidelines
The following tables give the history of cancer detection tests that have been recommended by the American Cancer Society for people who are at average risk for cancer (unless otherwise specified) and do not have any specific symptoms. These recommendations have changed over time as new tests have become available and as more evidence for or against the value of some of these tests has emerged.
People who are at increased risk for certain cancers may need to follow a different testing schedule, such as starting at an earlier age or being tested more often. Those with symptoms that could be related to cancer should see their doctor right away.

Doctors should discuss the benefits, limitations, and potential harms of lung cancer screening with patients who are in fairly good health*, in the correct age range, have at least a 30 pack-year history of smoking**, and are still smoking or have quit within the last 15 years. If patients decide to go forward with screening, they should have low-dose CT of the chest yearly through age 74 as long as they remain in good health. |

Low-dose CT of the chest |

The ACS recommends annual screening in adults ages 55 to 74 years in fairly good health* who: currently smoke or have quit within the past 15 years; have at least a 30-pack-year smoking history**; get counseling about quitting smoking (for current smokers); have discussed with their doctor the potential benefits, limits, and harms of screening; and have access to a center experienced in lung cancer screening and treatment. |

The most recent version of the ACS lung cancer screening guideline [from 2018] is being taken down while we review new scientific evidence to be included in the next update. While this important update is being completed, the ACS advises that clinicians, and individuals at risk for lung cancer, follow the recently updated recommendations for annual lung cancer screening from the U.S. Preventive Services Task Force (USPSTF), the American Academy of Family Physicians (AAFP), or the American College of Chest Physicians. |

Health care professionals should discuss the potential benefits and limitations of prostate cancer early detection testing and offer the prostate-specific antigen (PSA) blood test and digital rectal exam (DRE). If, after this discussion, a man asks his health care professional to make the decision for him, he should be tested (unless there is a specific reason not to test). |

Discussion and offer of testing should be done yearly for men with at least a 10-year life expectancy Discussion and offer of testing should be done yearly*** |
2010 - present |
Men should have a chance to make an informed decision with their health care provider about whether to be screened for prostate cancer. The decision should be made after getting information about the uncertainties, risks, and potential benefits of prostate cancer screening. Men should not be screened unless they have received this information. After the discussion about screening, those men who want to be screened should be tested with the prostate specific antigen (PSA) blood test. The digital rectal exam (DRE) may also be done as a part of screening. |
50 and over (average risk) |
Discussion at age 50 for men with at least a 10-year life expectancy and then periodically. If PSA is 2.5 ng/ml or greater, testing should be repeated yearly. Men with a PSA of less than 2.5 ng/ml may be tested every other year. |
45 and over (high risk**) |
Discussion at age 45 for men with at least a 10-year life expectancy and then periodically. If PSA is 2.5 ng/ml or greater, testing should be repeated yearly. Men with a PSA of less than 2.5 ng/ml may be tested every other year.**** |
