Where Can I Find Out More?

I have just learned that my brother has prostate cancer. Where can I find out more about this disease? I would like to know more about prostate cancer symptoms, so I know when I should get checked out by the doctor myself if it should happen to me. I also want to know more about the disease in general, the risk factors, how it is detected, the possible treatments and their side effects. I would like to be able to help my brother out by finding out more information for him, as I am sure he is thrown for a loop by this diagnosis and very worried.
