Prostate trouble at age 47

I developed prostatitis after having a biopsy to check for PC. My PSA was at 5.2 but I had no symptoms. I did have a slightly enlarged prostate and the urologist put me on Avodart after having the biospsy. During the next couple of weeks, I started having some symptoms of prostatitis. No bleeding or discharge, just had problems with sitting too long or walking too long. I had the feeling of swelling up inside my rectum. I went back to the urologist and he determined that I had prostatitis and he put me on Cipro also. After 2 weeks, I still had no relief and I contacted my primary care doctor about it. He did a digital rectal exam and said all felt fine... no hardness or nodules. He explained to me that due to the nature of the prostate which does not have a large blood supply to it, it took a longer time for antibiotics to work. That made me feel better about it. So I kept taking the antibiotics and finally it all was fine again. The downside of this story is that it turned out from my biospy I had low risk PC. 2 out of 12 core samples showed abnoral cells. They were very small amounts, but the cancer cells were present. Fortunatley, it was a non aggressive and slow growing form. My urologist told me about treatment options and also included active survailence where I would just be monitored for any changes before taking any action on a treatment. I chose to go for a treatment rather than wait. I just didn't want to know that I had cancer that was very treatable in it's current state - or wait until I was older and perhaps had other health problems to deal with too. Currently, aside form the prostate cancer, I am healty and I decided to deal with it and have it curred. I researched treatment options for low risk PC, - external beam radiation, Cyberknife, and Brachytherapy (low dose radiation seed implants). It seems the Brachytherapy has a better success rate and lower side effects - and I chose that treatment. It is a one time procedure and your done. The side effects will be with me for a few months as with the other treatment options. I am now in my 5th week after treatment and so far all is going well. The radiation oncologist told me the half life of the radation seeds is 4 weeks. After that, the side effects will beome less and less until they are gone. Side effects are fatigue from the radiation, frequent urination, a little burning when urinating... but all these side effects are not constant or do they occur every day... some days are fine and you can do most anything... the days when you are fatigued, listen to your body and take it easy on those days. And rememberr, prostatitis does not mean PC. But I would have your PSA checked and monitored... prostatitis can make your PSA number go up. My PSA started at 5.2, but after taking the antibiotics for 4 weeks, my PSA went down to 2.0 - but the biopsy confirmed the PC. Good luck to you.
