What questions do you wish you'd asked your healthcare provider about your prostate cancer?

From our Facebook community:
"Will surgery to remove my prostate shorten my penis and is there something that can be done to keep from losing so much length? We talk openly about women losing there breast in breast cancer and how emotional it is for them. It is emotional for them, but it is also emotional for men to loose penis size and length. My surgeon didn't and many are never told this will happen before surgery."

What stage is my cancer in, and what does that mean for my prognosis? What are the costs, benefits, and risks of each treatment option that's appropriate for me? How do I decide what is the best treatment option for me personally?
