8. Flutamide: Flutamide is a drug treatment included in the category of hormone treatment for prostate cancer. The growth of prostate cancer is triggered by male sex hormones known as testosterone. Cancerous cells have special proteins known as receptors which take up testosterone, which is an androgen. Flutamide is an antiandrogen, which means it works by stopping the testosterone from triggering the cancerous cells to divide and grow.
