I'm a bit concerned because my father has had laser prostate treatments twice before, once in 2011 when his prostate was 50mm, and then again in 2014 when it was 60mm. Despite that, he still has issues with prostate enlargement. By August 2015, his prostate had grown to 76mm. We decided to try ayurvedic treatment, and by October 2015, it's down to 56mm. Is this kind of fluctuation normal, and should we be worried about long-term effects or stability, especially since he has gone through both laser and ayurvedic treatments? Any advice on what to keep an eye on or consider moving forward?
