My uncle was diagnosed with prostate cancer 3 years ago they have been measuring his prostate since then  he has just been informed that his psa levels have increased from 16 to 62 (the highest ot has ever been) 

How high can psa levels reach. He was told at diagnosis that he has around 5 years and it is now coming up to 5. 

I dont like to ask my cousin too many questions as it makes her upset. 

Anyone got any information they can share. I do know that he has injections and it on a high level of medication. X 

Thank you
