Hi Sharron. So sorry to hear your news.
Did your dad attend the meeting with the consultant by himself. Is it possible he misunderstood.
IT doesn't sound like he was even offered palliative care and I'm pretty sure vitamins alone wouldn't count.
Would it be possible for you or another family member to ring his consultants secretary and ask for confirmation.
I have so far spoken to three different consultants' secretaries and without exception they have been a helpful as they can.
How old is your dad, how long has he had prostate cancer.
There are many members on here that can offer more relevant advice than I can so please hang in there until somebody comes along.
