My husband had laparoscopic prostate removal in April 2004. The pathology report indicated "marginal". For over 2 years, the psa was undetected. In October 2006, psa reading was 0.7 In February, 2007 it remained 0.7 I am extremely concerned with the Dr's advice to wait until June for another psa reading. I realize that a detected psa following prostate removal is not a good sign. My questions are...is the fact that the psa was undetected for over 2 years a positive or negative sign? Is time of essence when considering radiation for recurring prostate cancer? I am worried beyond belief that he is waiting another two months for possible radiation. The dr. indicated that sometimes scar tissue can cause an elevated psa following laparoscopic surgery. Would that not have shown immediately? Any advice you could provide would be helpful. Our urologist is qualified and a very skilled surgeon, but I strongly disagree with the "wait and see" approach.
