Welcome @Hubby2021 - congratulations on finding this site and for posting your queries.
Ditto all the above responses. Don't get ahead of yourself, take things one day at a time.
If you put your general location in your profile there may be another local lady who is able to be of more personal support for your wife, someone to natter with.
My husband (who has dementia) has been allowed to be with me in the ultrasound room but the mammogram rooms are usually far too small for another person.
Many (!) years ago when I had a 'lady' problem and was shy about seeing a doctor, and him seeing my lady bits, my Mum said "you are just a bit of meat to them so don't worry". I always remember that !
All the best to you both. Keep us updated.
