My dad has been having prostate symptoms for about 12 months, getting up to pee about 4 times a night, difficult flow, etc. Once I discovered this, I made him a GP appointment straight away. Following a physical examination and psa test at the doctors, my dad received an urgent referral for further investigations. He had his first hospital appointment yesterday which involved a biopsy procedure (12 x samples taken from prostate) followed by a meeting with a MacMillan nurse who explained the results will take about 3 weeks, at which point he will be called in for his results. She confirmed his psa level is 55 (he is aged 66) and the doctor who performed the biopsy confirmed his prostate was very enlarged and hard and that he is retaining a lot of pee, despite relieving himself. I am really concerned. 3 weeks seems such a long time to wait. Could anyone please confirm what happens after diagnosis? Does a psa level of 55 mean a cancer diagnosis is highly likely? TIA
