Hi All. I'm posting this because I'm concerned about my 76 year old father.

His annual routine blood work has all come back ok apart from his PSA which although apparently still in range at 4.5 is an increase from last years 2.6

His father died from undiagnosed Prostate cancer around this age.

He has no symptoms at all and has been to the urologist who did a physical examination and said his Prostate is not enlarged. He advised he was not concerned it would be anything too sinister with a level of 4.5 however they could wait 6 months and do a repeat PSA or do a biopsy in a week or so.

My dad has chosen to go for a biopsy but I've read this can be quite painful and can also miss cancer. I've read an MRI could be a better first option as many have unnecessary biopsies and I'm scared about sepsis
 

He's not UK based and this will be done with the private healthcare. 
 

Any advice would be appreciated.
