NCT ID NCT04589468
First seen Jun 26, 2026 · Last updated Jul 24, 2026 · Updated 2 times
Summary
This study explores whether aerobic exercise, like walking, can lower levels of ctDNA (a marker of cancer in the blood) and help prevent breast, prostate, or colorectal cancer from coming back. Researchers will test different amounts of weekly exercise (90 to 375 minutes) in 33 people who have already been treated for cancer. The goal is to find the safest and most effective exercise dose to test further.
