Hey Bryan and KPC,
Sorry been AWOL recently with other life stuff(!) but I hope your got some reassurance from your consultant Bryan?
Both of you are exactly at the time where you'd expect to see bounce. Any increase after BT before 30 months is much much more likely to be bounce than failure. It's really only after 30 months that you start to wonder a bit more about wtf is going on! Even then, it may be 60 months before reaching true post procedure Nadir.
As I've said before, it's a long old journey and for me, that's the only downside of the treatment choice in my experience so far.
So, if you can, it's definitely best to stay positive and not exert too much brainpower on what I'm sure will be a temporary rise!
Logic should tell you that it's unlikely cancer would cause such a sudden increase - even without treatment you wouldn't necessarily expect to see that sort of rise in that sort of time. The fact that your prostate and the cancer in it has been, or is in the process of being, obliterated by radiation makes it even less logical that cancer should now be causing the rise - right? Right!
In fact many studies have shown bounces before 30 months to be a good indicator of future success. Almost all bounce patients end up being BCR free compared to non bounce patients and when you consider that it's a very small cohort who fail after BT anyway, having a bounce should actually be reassuring!
Of course, it's easy to say that and definitely not so easy to get the brain to accept! We all just want to see a straight line down and its natural to panic when it doesn't do that. But stay positive and take reassurance from the fact that bounce is a very real thing, you're at exactly the right time to experience it and ultimately it's a good prognostic indicator of future success!
