question: Ive just completed my annual physical and my PSA level went up to 6.0.  2010 was 3.8 and 2009 was 2.5.  Prior to that my levels were 1.0 - 1.4.  My question is this, my son just passed away unexpectantly and I have been under a lot of stress.  Can this type of stress and depression have any effect on my PSA numbers?  Ive also been exercising a lot more to try to help with the stress, could that have an impact on my recent PSA test?Thank you very much!
