Hello and welcome Lyndyloobooth,
When you see the consultant on Tuesday take notes as you might not remember everything that's said. It may be worth writing out some questions beforehand.
Your husband's PSA is quite high but there on some on here who had PSA in the 1000s, mine was 408. Click on my (and others) avatars to see their respective journeys with PCa.
Download the Toolkit from the publications section on this website, you'll find the info there very helpful. You can also speak to the specialist nurses here.
When you get the results post them on here and update your profile and others will be able to help you with advice etc. We're not generally medical people but are people who have PCa or the partner of someone who has it.
Feel free to ask any questions however stupid they may seem, someone will have experience in what you're asking and they will be able to help you.
Try not to Google regarding this as it isn't always helpful.
Best wishes
Arthur
