Summary

This study looks at whether eating a diet rich in cruciferous vegetables (like broccoli, cauliflower, and cabbage) can help prevent bladder cancer from coming back in people with intermediate to very high-risk non-muscle invasive bladder cancer. About 250 participants will either follow this special diet or continue their usual eating habits, alongside standard treatment. The main goal is to see if the vegetable-rich diet improves the chance of staying cancer-free for at least one year.
