Cancers With Routine Screening—and Cancers Without One

Some cancers have recommended screening tests for certain men. Many do not. Learn the difference and why more testing is not always better.

The direct answer

Routine population screening exists for colorectal cancer, lung cancer in high-risk smokers, prostate cancer in selected ages, and abdominal aortic aneurysm. There is no routine blood test, urine test, or imaging scan that screens for pancreatic, brain, testicular, kidney, or most other cancers in average-risk men.

Cancers with recommended screening

Colorectal cancer screening starts at 45 for average-risk men and continues through 75. Lung cancer screening with low-dose CT is for adults 50 to 80 with at least 20 pack-years who currently smoke or quit within 15 years. Prostate screening is an individual decision for men 55 to 69. AAA screening is a one-time ultrasound for men 65 to 75 who ever smoked.

Each of these tests targets a specific cancer in a specific high-risk or age-defined group. They are not blanket cancer-detection tools.

Colorectal cancer: starts at 45.
Lung cancer: high-risk smokers and recent quitters ages 50 to 80.
Prostate cancer: individual decision ages 55 to 69.
Abdominal aortic aneurysm: one-time ultrasound for men 65 to 75 who ever smoked.

Cancers without routine screening

Many cancers people worry about lack routine screening tests. There is no recommended population screening for pancreatic cancer, brain cancer, testicular cancer, kidney cancer, bladder cancer, or most blood cancers in average-risk adults.

Some companies market blood tests or whole-body scans that claim to detect multiple cancers. These technologies are still being studied and are not substitutes for the established screenings above.

Why more screening is not always better

Testing for cancers without good screening tests often leads to false positives, incidental findings, unnecessary procedures, and anxiety. Whole-body MRI, for example, can find harmless lumps that lead to biopsies or surgery without improving survival.

The goal is not to scan everything. The goal is to use tests that have been shown to help people live longer or healthier lives. What this does not mean: it does not mean cancers without screening tests are untreatable or hopeless. It also does not mean a real symptom should be ignored just because no screening test exists for that cancer. It means that routinely testing healthy, average-risk people for those cancers has not been shown to save lives.

What to do instead of panicking

Focus on the screenings that are recommended for you, know the symptoms that should prompt evaluation, and avoid the temptation to buy peace of mind through unproven scans. A sensible prevention plan is usually boring and evidence-based.

If you are concerned about a specific cancer because of symptoms or family history, tell your clinician. Targeted evaluation based on symptoms and risk is different from routine population screening.

Ask: 'For my age and risk, which screenings are actually recommended?'
Ask: 'Would this marketed test change my management, or just find things we cannot act on?'

Frequently asked questions

Is there a screening test for pancreatic cancer?

No. There is no routine screening test for pancreatic cancer for average-risk adults. Research is ongoing, but broad population screening is not currently recommended.

Can a blood test screen for all cancers?

No single blood test can reliably screen for all cancers. Some multi-cancer blood tests are being studied, but they are not a substitute for established screenings like colorectal, lung, and prostate screening discussions.

What about testicular self-exams?

Major guidelines do not recommend routine testicular self-exams for all men because they have not been shown to reduce deaths. Men who notice a new lump, pain, or swelling should see a clinician.
