What is bladder cancer?
Bladder cancer occurs when cells in the lining of the bladder grow
and divide in an abnormal, uncontrolled way. There are three main types
of bladder cancer. Approximately 90% of bladder cancers are urothelial
carcinoma, which begins in urothelial cells of the bladders lining. The
less common types are squammous cell carcinoma (develop in the bladder
lining) and adenocarcinoma (develops from glandular cells).
You can access further information about bladder cancer, including
risk factors, symptoms, diagnosis and treatment from

The Victorian Cancer Registry also operates an interactive web
portal,
Data
Explorer, which provides more trends and statistics than published

How common is bladder cancer?
In 2024, 808 Victorians were diagnosed with bladder cancer. Of these,
there were 607 males and 201 females, representing 75% and 25% of the
total Victorian bladder cancer diagnoses, respectively. Currently,
bladder cancer is diagnosed at a rate of 14 per 100,000 males and 4.1
per 100,000 females. The median age at diagnosis of bladder cancer is 74
years in males and 75 in females (Figure 1 & 2). Accounting for 2%
of all cancers diagnosed and 3.1% of all cancer-related deaths in 2024,
bladder cancer was the 12th most commonly diagnosed cancer and the 10th
most common cause of cancer-related deaths in Victoria.
Trends in bladder cancer over time
Figure 3a shows for males between 2007 to 2024 the age standardised
incidence rate of bladder cancer declined by an average of 1.5% per
year.
For females between 1995 to 2024 the age standardised incidence rate
of bladder cancer increased by an average of 0.06% per year. However
this result wasn’t statistically significant, meaning the change cannot
be confidently considered real and may be due to random
fluctuations.
Bladder cancer morphology
Figure 4 provides a summary of the different types of cells
(morphology) which have caused bladder cancer among all cases. Most
bladder cancer tumours, 90%, present as urothelial carcinoma
tumours.
Geographical variance in bladder cancer by local government
area
Figure 5 demonstrates variation in the estimated risk of being
diagnosed with bladder cancer, by local government area, relative to the
Victorian average. Red shading indicates areas with higher risk and blue
shading indicates areas with lower risk relative to Victoria.
Bladder cancer in people born overseas
Figure 6 shows the standardised incidence ratios (SIRs) of bladder
cancer in Australian-born Victorians compared to other major migrant
groups, over the five-year period 2019 to 2023. The highest standardised
incidence ratio (SIR) for bladder cancer was 1.3 for males born in the
Other Europe region and the lowest SIR of 0.46 was observed in males
born in the South-East Asia region. The highest standardised incidence
ratio (SIR) for bladder cancer was 1.4 for females born in the North
America region and lowest SIR of 0.31 was observed in females born in
the South-East Asia region.
Bladder cancer five-year relative survival
Figure 7 shows the change in 5-year survival for bladder cancer, and
the 5-year survival trend for all cancers over the same time period. It
demonstrates that five-year relative survival has decreased for bladder
cancer between 1985-1989 and 2020-2024 from 70% to 57%.
