read that for older men brachy has a bit better results.
if not agrressive cancer cell type, he should be o.k. for a long long time.
everyone is different and results can differ for the same treatment.
I recall technician tell me they killed everything . machines so precise.
its been 2 years and my psa, which is a marker only, has slowly gotten lower and sits as of yesterday at .6
i am 75, so i figure if it does not kill me, something else will later on. we are not immortal.
todays medical knowledge and drugs means its not that death is imminent.
so, enjoy life as best you can.
as i always say, a bus can come along and kill the healthiest too.
