Bruce, similar info to what I was told in 2012. This was not the time I wanted to become an expert and make one of the more important decisions about my life. This is a polarizing topic on the site. As folks above mention get several opinions, find both younger and older RO's, they tend to have differing views which are important to understand. Some factors which I considered were... Existing health, access to screening, personal ability to live with higher uncertainty, my family's ability to handle uncertainty, oral health, QOL in 15 years, etc... It is a tough one, I involved a couple close family members in help me. There is no looking back, you simply make the best personal decision based on the very imperfect info available.
