I was looking at one of those many PC calculators and it asked if the cancer was unifocal or multifocal. I'm not sure what that means. Does unifocal mean 1 positive core and multifocal >1, or are they talking about something else?

Compiler, multifocal means that there was cancer found in more than one area with unifocal meaning only one area had cancer. Prostate cancer is generally a multifocal disease. In fact, the average surgical specimen after prostatectomy contains 7 areas with cancerous cells.
Husband diagnosed in 2/2008 at age 57 with stage T1c. Robotic surgery performed 3/2008. Stage upgraded to T3a (single small EPE in posterior left). Perineural tumor infiltration present. Apex margin, bladder neck and SV negative. Final Gleason 3+4 SA. PSA: 0.0 til July 2009. August 2009 PSA was 0.1, in September it was 0.3 Met with radiation oncologist, CT scan and bone scan clean. Third PSA on October 16 - PSA BACK TO UNDETECTABLE! Next PSA scheduled for early December. No radiation treatment at this time!

PCa was described to me as a Swiss Cheese disease. It starts all over the place all at the same time. Isn't that weird? It's as if some switch is turned on and it starts to go bad from the inside out.
