Hello my dads PSA was 70 a year ago he was ment to go back for more tests as his prostate was slightly enlarged he didn’t go back for a whole year now it is 200 he is 80 years old and when my mother was asking him what that ment he shut the conversation down and refused to talk about it this is very out of character for him and he walked out . The nurse has done more blood tests again today and said testing for prostate cancer . He has problems weeing stops and starts . He had a heart attack many years ago and diabetes no other problems. Can the 200 mean other things other than prostate cancer
