Bladder cancer in women: four years of missed diagnoses behind UTI labels

By Dr HB Lo, FACRRM 4 min read
Verdict Yes — worth knowing about

About 3,345 Australians are diagnosed with bladder cancer annually. Unlike most cancers, the five-year survival rate has fallen since 1987 — and women's survival (approximately 50%) is measurably lower than men's (approximately 60%).

A key driver is later-stage diagnosis in women. Symptoms such as blood in the urine and urinary frequency closely resemble UTI symptoms, and in women these are frequently attributed to infection — or to perimenopause — before further investigation occurs. Experts advise that blood in the urine should always be investigated, and that more than two UTIs in six months (or three in a year) is an indication for further workup including possible urology referral.

What just happened

ABC Health has published a feature on bladder cancer diagnosis in women, and the picture it draws is of a diagnostic system that is failing a substantial proportion of women by attributing their symptoms to something less threatening.

Bladder cancer is predominantly diagnosed in men — about three in four Australian cases — which is part of why the pattern of delayed diagnosis in women has been slow to surface. About 3,345 Australians are estimated to be diagnosed with bladder cancer each year. The five-year survival rate is approximately 50% for women and approximately 60% for men. Unlike most cancers, that survival rate has actually fallen since 1987.

The survival gap is not a biological difference. It is, experts say, largely a difference in stage at diagnosis. Women are presenting later — and they are presenting later because their early symptoms are being attributed to something else.

Blood in the urine. Urinary frequency. Urgency. In a man aged 60, those symptoms prompt investigation. In a woman, they often prompt a UTI swab and a course of antibiotics.

Both-and

Why this happens — and why it is not simply clinical error

The overlap between bladder cancer symptoms and UTI symptoms in women is genuine. UTIs are significantly more common in women. The presenting symptom profile — dysuria, frequency, haematuria — is shared. A GP seeing a woman with haematuria and dysuria is, in purely probabilistic terms, more likely to be right that it is a UTI than that it is a malignancy.

Dr Magdalena Simonis, a GP and women’s health expert at the University of Melbourne, explains that in men, any blood in the urine is typically investigated immediately because UTIs are rare in that population. In women, the calculus has historically been different — and the clinical pathway of treating the infection and reviewing if symptoms persist is not unreasonable as a first step.

The problem begins when symptoms recur and the same assumption continues to drive the loop. Andrea Harris had four years between her first GP consultation for a suspected bladder infection and her March 2024 diagnosis with stage three muscle-invasive cancer. Four years of antibiotics that eased her symptoms for weeks at a time before they returned.

Perimenopause adds another layer of attribution. Women aged 45 to 55 presenting with urinary frequency or changes in bladder function can have those symptoms folded into the perimenopausal picture without a specific investigation of the urinary tract.

The surveillance gap is modifiable

Clinical guidance provides a clearer trigger than is often applied in practice. More than two UTIs in six months, or three or more in a year, should prompt further investigation and possible urology referral. That threshold exists precisely because recurrent infection is also a pattern that can mask an underlying malignancy.

Additional risk factors that should raise the clinical index of suspicion are not exotic: smoking history, age over 40, prior pelvic irradiation, occupational chemical exposures. These are all available in a standard GP consultation. They are not routinely surfaced when the presenting symptoms fit a common, benign pattern.

Bladder cancer is not a condition confined to older men. Christine La Rose — a bladder cancer survivor and support lead for BEAT Bladder Cancer Australia — was diagnosed at 49. She initially had blood in her urine attributed to a UTI, which caused a short delay. She reports meeting women in their 20s, 30s, and 40s at diagnosis. The demographic assumption that bladder cancer is unlikely in a woman under 60 is part of the problem.

Margaret Blake saw three GPs within six months about frequency and haematuria. It was the third GP — the first to refer for testing — whose referral led to her diagnosis. Three consultations before the question changed from “infection?” to “what else could this be?”

What general practice can do

The clearest single change is to treat visible or microscopic haematuria in women as a finding that requires explanation, not a finding explained by the UTI until proven otherwise. If antibiotics resolve the infection but haematuria persists, that persistence requires a workup — not another empirical antibiotic course.

Dr Simonis is explicit that smoking history and age should factor into the risk stratification for women presenting with UTI-like symptoms. A 50-year-old woman with a smoking history presenting with recurrent haematuria is not a low-risk UTI patient. The clinical framing should match that risk profile.

My two cents

This is a diagnostic-delay story, not a mystery. The reasons women are diagnosed at later stage are understood. The pathway to earlier diagnosis does not require new technology — it requires applying existing thresholds more consistently, and adjusting the clinical prior for women whose UTI-like symptoms have become a pattern rather than an isolated episode.

If you have had more than two UTIs in the last six months, or your symptoms have recurred after antibiotic courses that did not fully clear them, it is worth asking your GP specifically about further investigation of the urinary tract — not just treatment of the next infection. Blood in the urine is always worth investigating, regardless of whether the presentation looks infected.

The survival gap between women and men with bladder cancer is not inevitable. It is an artefact of when each group is found.

Verdict: yes — this diagnostic gap is real, the trigger thresholds are well-established, and this is worth knowing about this week.

Frequently asked questions

  • What symptoms of bladder cancer are women most likely to have dismissed?

    Blood in the urine — either visible or detected on dipstick — is the most important finding and should always be investigated rather than attributed to infection alone. Other symptoms include urinary frequency, urgency, a sudden change in urine colour, loss of appetite, and unexplained weight loss. The difficulty in women is that haematuria and frequency are common UTI symptoms, and repeated short courses of antibiotics can temporarily ease symptoms without addressing an underlying malignancy.

  • When should a woman with recurrent UTIs be referred for further investigation?

    More than two UTIs in six months, or three or more in a year, should prompt further investigation and consideration of urology referral — particularly in women aged over 40, smokers, and those whose symptoms are not fully explained by confirmed infection. Urine cytology, renal tract imaging, or cystoscopy may be appropriate depending on the clinical picture.
