First Symptoms - Questions

Thanks for the encouragement. I'm stil awaiting TURBT so no definitive diagnosis yet.

Guess I'm a bit of a doom and gloomer. Living in uncertainty while waiting for surgery has me thinking of a lot of things I might have missed or approached differently. Then, probably mistakenly, jumping to conclusions as to how those in/actions might impact my diagnosis.

In short, driving myself crazy.

Recently diagnosed, first symptom was brown urine a couple of weeks ago. Or so I think.

However, I am troubled by an incident that happened 4 years ago I had burning urination (no visible blood) which I thought was a UTI. I went to an urgent care center where they prescribed an antibiotic which cleared it right up (w/in 48 hours). The odd thing was that no infection was indicated in the urinalysis.

I later mentioned this to my PCP who seemed comfortable that it was resolved since I had no further symptoms. In fact, until recently I had no symptoms of any sort for the intervening 4 years.

Now that I've been diagnosed, I'm second-guessing everything. Has anyone ever heard of a similar experience? Could I have missed an early warning sign that then went asymptomatic for four years? I'm beating myself up over this one.
