It's stopped. Do I still need it checked?
Yes — and this is the question that matters most. Bleeding from a bladder tumour is typically intermittent: it comes, it goes, and the gap is often weeks. Visible blood in urine is investigated on the basis that it happened at all, not on whether it is still happening at the appointment. Many delayed bladder cancer diagnoses follow exactly this pattern of one alarming episode that resolved.
Is painless bleeding less worrying?
No — the reverse. Painful bleeding usually means infection or a stone. Painless visible blood in the urine is the classic presentation of bladder cancer, and the absence of pain is precisely why people wait.
Isn't it just a urine infection?
It might be — but a UTI causes stinging, urgency and frequency alongside the blood. Blood without those symptoms is not a UTI, and neither is blood that persists after an infection has been treated. Repeat urine testing after treatment is important, because "it was just a UTI" is another route by which serious diagnoses get missed.
I'm on warfarin or a blood thinner — doesn't that explain it?
No, and this is a common and costly misunderstanding. Anticoagulants do not cause bleeding from healthy tissue; they unmask a source that was already there. Bleeding on an anticoagulant is investigated exactly as it would be otherwise — arguably with more attention, not less.
I only get it after running or cycling.
Exercise-related blood in the urine is a genuine phenomenon, particularly in long-distance runners. But it is a diagnosis made after investigation, not instead of it. Get the first episode checked; if everything is clear and it recurs only after hard exercise, that becomes a reasonable explanation.
The dipstick showed blood but I can't see any. Does that count?
It matters less, but it is not nothing. Non-visible (microscopic) blood found on testing warrants a check of kidney function and blood pressure, and further investigation if you are over 60 or have other symptoms. Visible blood is in a different and more urgent category altogether.
What tests will I need?
Typically urine testing to exclude infection, kidney function and a full blood count, and in men a PSA. Visible blood generally leads to urology referral for a cystoscopy and a scan of the kidneys and bladder — a camera test of the bladder, which is the only thing that reliably settles it.
How quickly should I be seen?
Visible blood in the urine at any age warrants urgent assessment, and over 45 it usually triggers an urgent suspected-cancer referral. We can take the history, arrange the bloods and urine tests, and make that referral — which is often the most useful thing, because getting onto the right pathway quickly is what changes the outcome.
