Hopefully the biopsy is negative to cancer and the rise of PSA is due to BHP. The gland’s volume could mean just that.
In any case you should be prepared for the news and try knowing the terminology to better understand your doctor. The American Society of Clinical Oncology offers advice on procedures and a list of questions which you may adapt to your own list.
Just type “Questions to Ask the Doctor” in a search engine.
This is a worrisome period in your prostate issue. I recall being nervous when visited the doctor (in 2000) to receive the diagnosis. My first reaction to the positive results was to deny it. I though it being a misinterpretation by the pathologist or a mistake, exchange of biopsy samples from another patient.
It will be good to be accompanied by a family member.
Hope for the best.
