Hi Heather
This is a really good place to get some friendly support when you need it the most. We have a lot of daughters who have Dads that have PCa posting on here regularly.
It sounds like you want to be involved with your Dad's journey, you have not said if your Mum or another significant partner is also there supporting him.
Have a chat with Dad and let him know you want to be supportive and if you can maybe go with him when he sees the consultant.
The scan results should be ready by now but what happens next depends on the initial review by the consultant radiologist. Sometimes they need to be reviewed at a special meeting called a multi disciplinary team meeting. This is where consultants and specialist nurses,radiographers etc. from radiology,urology,oncology discuss patients and how as a team they will take the next steps. These usually happen once a week towards the end of the week. The cases they review are normally prioritised by level of urgency. So it can take a while. Then a follow up appointment should be made for your Dad.
If he is concerned then he can ring the consultant's secretary and ask them to check what is happening.
Your Dad may be used to dealing with this in his own way and he may be trying to protect you from the clinical side of things, he could also feel a little awkward about the intimate nature of this disease. So he might need time to get comfortable sharing some of this with you his very young and lovely daughter.
I wish you all the best
