His PSA dropped really nicely (knock the wood) and as far as I know most doctors will consider that undetectable and as no reason for further treatment at this point. However, if your partner's cancer is highly aggressive, it is very wise to have MO consultations and it is excellent plan. My husband also has very aggressive cancer and our MO suggested that perhaps we should start thinking about early salvage when and if his PSA reaches 0.05 and than have radiation therapy at 0.1. Since your partner's first ( the very first we do not count because it was just a "trend test") PSA is 0.07 they might want to wait for the next one to see if there is any movement upward at all. You see, it all so individual and depends of so many factors that it is impossible to predict "when" the next treatment will be. The only thing that is for sure is that it will happen if his PSA ever comes to 0.2 (or 0.1 if you decide to do early salvage therapy ) and it will be radiation with probably short ADT . If you have good doctors try to relax now somewhat, I know that it is very hard < 3, I am working on that still. Just stay on top of the things and results, visits and doctors, all the rest is out of our control. His PSA might stay stable at 0.07 for many years too : )))) ! One never knows < 3
Wishing you the best of luck with the next PSA test and super successful consultations with your MO

PS: Since I want to be extra diligent, I make my husband take PSA test every month - it gives me a peace of mind
