Why Some Screenings Should Start Sooner Than Guidelines | Peter Attia
Peter Attia argues that several cancer and disease screenings should begin earlier than current medical guidelines recommend, challenging the status quo with evidence-based rationale. He emphasizes that diagnostic tests should only be pursued if their results would meaningfully change treatment decisions, and discusses specific screening protocols he recommends for his patients, including earlier colonoscopy and aggressive PSA testing.
Key takeaways
- • Colonoscopy screening should ideally start at age 40 rather than the recently updated guideline of 45, according to Attia's assessment of colorectal cancer risk.
- • Coronary imaging is particularly valuable for patients who are hesitant about managing cardiovascular risk factors, as visual evidence can motivate behavioral change when social media misinformation creates doubt.
- • Apo LP(a) blood testing should be performed annually to identify genetic cardiovascular risk factors that warrant intervention.
- • PSA testing should be conducted annually on all males as a non-negotiable screening measure, since PSA levels can fluctuate for non-pathological reasons and early detection matters.
- • Low-dose CT scans for lung cancer screening are underutilized despite lung cancer being the leading cancer death cause; annual screening mitigates false positive concerns through serial follow-up.
- • The fundamental principle for any diagnostic test is ensuring the result would actually change your treatment approach—if the answer is no, the test shouldn't be performed.

"I'm really happy to see that the guidelines for colonoscopy were moved from 50 to 45. I think that's an excellent step in the right direction. I would personally move it up one step closer to 40."

"We talk about blood markers like apo LP little A. I think that should be done, but you know, everybody buys themselves one of those a year."

"We actually recommend low-dose CT scan for lung cancer screening. So lung cancer is the leading cause of cancer death in men and women by far."
