Hello Willmay and a belated welcome from me.
That initial shock of diagnosis, especially with no warning symptoms, can really take it out of you and I'm sure must make it worse if you are someone who likes to be in control and know the "whys" and wherefores" .
I speak as one who is much the same!
My husband didn't have symptoms either and his diagnosis was only on the last minute addition to a blood test form by our GP after he went there with a bad back, the origins of which we knew were caused by an accident in the garden.
It is very early days for you both and believe it or not, it will get easier when you get results and confirmations and a treatment plan in place.
Life is never the same again, never normal as it was, but you will adjust to the new normal.
The toolkit is excellent. Don't forget to write down your questions for your consultation and if you can write down the answers. I'm pretty sure that even though there will be both of you in the room, you'll both hear the answers differently - even if it is only in the tone that something is said.
You've found us now, and you know what we are like. Supportive !!
Come back and let us know what the result of the scan is and what treatment is offered. I'm sure that somebody will have the knowledge to advise you.
