Early Detection Decreases Likelihood of Death

Screenings can identify cancer before symptoms appear.

Screenings are tests for a disease when the patient has no symptoms or history of that condition. Regular screenings may find cancer early, which is when treatments usually work best.

Detectable cancers for which screening is possible largely affect1 Non-Hispanic American Indian and Alaska Native populations. These include colorectal, lung, female breast, and cervical cancers.

Lung Cancer Screening

The U.S. Preventive Services Task Force3 recommends annual lung cancer screenings4 with low-dose computed tomography (LDCT) for people who have no symptoms, but at are high risk because of their age and smoking history.

Candidates must meet the following conditions:5

  • History of heavy smoking (20 pack-year or more), and
  • Smoke now or quit within the past 15 years, and
  • Between 50 and 80 years old

If you think you may be a candidate, discuss this screening with your physician.

What can you expect during an LDCT scan? Patients will lie on a table, while an X-ray machine uses a low dose of radiation to capture photos of your lungs. This is not a painful screening, but repeated LDCT tests may cause cancer from radiation exposure.

What is a Pack-Year?

An average of one pack of cigarettes per day for one year

Unfortunately, there is no evidence available to indicate that screening for the following cancers can reduce the likelihood of death: ovarian, pancreatic, prostate, thyroid.

In addition, the U.S. Preventive Services Task Force3 has not determined5 whether the benefits outweigh the harms of screening for bladder and oral cancer, as well as visual skin screening for skin cancer.
