It's all very worrying for you both at this stage as there seems to be so much happening so quickly as you are suddenly on this rollercoaster ride where not a lot seems to make any sense.
I am not qualified to offer opinions on medical matters but having been through this I can tell you that once you have the outstanding results you will be in a much better situation as you will then be able to work with your medical team to decide how to move forward.
I would suggest that if you haven't done so, either download the Toolkit from this site or phone and ask for the printed version to be sent to you. If you can, take a deep breath, make a cup of tea and sit and read this information you will begin to realise that there are so many treatments out there for this disease that life can continue almost as normal. I am a Gleason 9 and was diagnosed in 2015 but I am still carrying on more or less as before with a couple of adjustments due to side effects of treatment but they don't stop us getting on with our lives.
There are so many men on this site who have had much higher PSA readings than me (some in the thousands) and they are still battling on.
There are challenges to meet along the way whatever treatment you have, but I found that by reading about them beforehand I was mentally and physically prepared to meet them head on as they occurred. I am still out walking, riding my motorbike, driving school buses and having holidays as well as the usual household stuff along with the garden and doing jobs for neighbours.
The easy thing to say is 'try not to worry' but do try not to. You will get used to waiting for test results with prostate cancer and it becomes a part of your life but that's a small price to pay. There is nothing to be achieved by worrying but you can help yourselves by going through the toolkit and is all starts to make sense you will hopefully realise that between you and your medical team you can take some control back.
All the best and keep us posted. If you click on the avatars of members you can read through their stories.
