Kbry, At this point, given the rapid rise, it sure sounds like infection rather than cancer. A few things to think about
that (may) help you settle down.
PSA has been compared to the 'check engine light' on your car. It means something is happening down there, and the list is long. The standard approach to a fast rise in PSA is a course of antibiotics before you do anything else. And this change from 2.4 to 7.2 in a month would be very unlikely from cancer. PC just doesn't grow that fast 99% of the time.
Also, there are lots of other things besides PC and infection that can cause PSA to jump. Does he ride a bicycle or a horse? Did he have sex less than 48 hours before the last blood draw? Did (and some docs actually do this and should know better) he have a digital exam BEFORE the blood draw?
The good news, the silver lining in this, is that PC is almost always a slow grower, and many of us were told at the time of our diagnosis that we had up to 6 months to decide what course of action we wanted to take. In that sense, PC is not like any of the other common cancers, where there is no waiting allowed.
