About this study

Low grade non-muscle-invasive bladder cancer (NMIBC) often recurs after treatment, requiring repeated surgeries, especially in older patients. These recurrences can cause complications, reduce quality of life, and increase healthcare costs. Currently, there is no well-tolerated preventive treatment routinely used for patients with low-risk disease. This study will evaluate whether dutasteride, an oral medication that blocks androgen activity, can reduce the risk of bladder cancer recurrence. Dutasteride is generally well tolerated and easy to take. The study will also assess its safety in women. The goal of this study is to determine whether dutasteride can provide a simple and effective way to prevent recurrences of low grade non-muscle invasive bladder cancer.
