QUESTION: am I correct that most causes of frequent urination is from prostate not cancer.should I occasionally take  tomataojuice to compenstat loss of sodiumfrom riexcess urination


Frequent urination is much more likely to be from prostate enlargement. There is no need for tomato juice or any other extra sodium source as there is little sodium in the urine and it is quickly made up by a standard diet. Plus you risk sodium excess. The frequency is a bladder/prostate issue and not a urine overproduction problem.
