Men with prostate cancer deserve answers clearly backed up by evidence published in medical journals. Questions you must ask your doctor if you are considering proton radiation:

1. Have you personally published your proton radiation results in a medical journal?

2. For my stage of cancer, what is the published likelihood that:

• I will be cancer free 5 years from now?
• I will be cancer free 15 years from now?

3. Why is my risk for developing a new secondary cancer greater after proton radiation?

4. What is the published likelihood of maintaing my erectile function and urinary control (continence) after proton radiation?
