Had my first 'fanny cam' at 55 just because.....Doc said good for another 10 yrs.
Just had my first (and last I hope) 'Pee Pee Cam'
I get routine tests due to thyroid meds. Found microscopic blood in urine.
Had the camera scope of bladder......nothing. CAT scan showed tiny, tiny stone in right kidney.
Point is I had NO symptoms of any problems.
So get that 'fanny cam' done at least at age 50.
And get blood/urine tests done just for piece of mind.
And pay attention to any symptoms...change in weight, fatigue, mood swings etc.
Your body will talk to you...listen up!
There are several private labs that do testing inexpensively.
