Broccoli vs. bladder cancer: could your diet keep tumors away?
NCT ID NCT06733363
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a healthy eating program that encourages people with early-stage bladder cancer to eat more cruciferous vegetables like broccoli, kale, and cabbage. These veggies contain natural compounds that may help fight cancer cells. Researchers want to see if this diet change can lower the chance of cancer returning or getting worse. The study involves 344 adults in New York State.
