Mike:
Some thoughts on your post and others on this thread:
1. If you can live with the fact that cancer might be growing slowly in your body, why not consider diet and active surveillance? If you do consider this, please consult a physician experienced with the approach.
2. In answer to your specfic question, my answer is similar to JohnT's answer, i.e. seeds in early stage PCa provide equal cure rates to surgery, other radiation or any other treatment, with fewer SE's.
3. Diane's point re potential problems is well made and true with any treatment you choose. However, if you choose radiation and the cancer returns you should scratch salvage surgery from your vocabulary. It's high risk, especially for bad SE's as Diane and Pete will readily attest.
4. Today's brachytherapy with experienced docs can yield the trifecta of cure, easy treatment and limited side effects. I don't know about the Indy guys, but Dattoli is very experienced, uses color doppler and has a great track record.
Good luck,
