Stay POSITIVE! "Focally involved" is much better than "Locally involved" as it means only a small area. And the focally involved area was Gleason 3+3 which was less than the overall Gleason 3+4.
In my post-op pathology, I had 2 positive margin "focal points" which were explained to me as only a contact area of one or two cells which most likely were also removed in the overall sugical traumas to the tissues. My initial "no-reoccurrence" numbers for 7 years were 94% then. Anyway, my first post-op psa at 3 months was < 0.1... which is "zero"... Note that my doctor does not do a 6 week psa as there may still be some pre-op psa still in my system and he does not like the chance of that occurrence to unneedingly worry patiernts. Anyway, with that 3 month psa at "zerro", the stats get much better for no re-occurrence.
There are also other factors as to which lobe the contacts are in... You can always ask your doctor for more info or sites to look up this information... to better define focally and which lobes and what that means... Beside the doctor's info, I found a lot of additional info on this site and also seaching with google... Comforted me a lot...
One of our members, sorry, forgot which one :-( , has the quote "Cancer feeds on fear... Starve it!"
I have found the more I ask questions and understand this stuff, the better my brain and emotions handle it... Information lessened fear... I become more part of the team actively fighting this darn disease!
