Thanks for sharing your situation and asking for input. I would be curious to learn what sequence of events led to the biopsy, such as the PSA history. That being said/asked, it is perfectly normal to have unsettling feelings about the idea that cancer is in your body, however time is definitely on your side to make an informed decision. Self-education will be an important part of making that informed decision and it can feel overwhelming at first, but when you start asking questions based on your knowledge, you will feel that much better about how to interpret the answers from the professionals. Take a look at this article about life expectancy https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4923265/ to get a sense of where your husband fits into the curve of 50-59 years old, it all relates to his PSA at initial diagnosis.

Published studies from centers of excellence and clinical/trial studies that often times are rooted in new treatment methods will provide you with the largest sample size of information, however the forums will provide you a human-element and individual experiences. You will be able to find contradicting/inconsistent individual experiences, that is just a normal aspect of life, so value the input but also balance it with your knowledge base and also your personal feelings (which are the most important) in terms of how you deal with risk, uncertainty, how you define quality of life, and other factors.

be calm and stay strong, you have many options ahead.
