We take stock of the prevalence of bladder cancer in Italy, based on official sources.

In 2024, about 31,016 new cases of bladder cancer were diagnosed in Italy, up from previous years. - Source: fondazioneveronesi.it
-25,227 in men
- 5,789 in women

- Men: 78.8 cases per 100,000 population per year.
- Women: 15.4 cases per 100,000 population per year. - Source: reteoncologicacampana.it

Annual incidence provides timely insight, but to estimate cumulative risk over a lifetime, incidence rates can be applied to average life expectancy.

A simplified method:
- If we consider a man's life expectancy up to ~85 years.
- A constant rate of 78.8/100,000 in men corresponds to about 6.7‰ per year (78.8 ÷ 100,000 × 1,000).
- Accumulating for ~85 years (without considering mortality from other causes), we get a crude estimate of: 6.7 × 85 ≈ 569‰ or ~57%, but this is anobvious overestimate because it ignores mortality from other causes and changes in risk.
- More accurate estimates based on registries (AIRTUM, AIOM) and epidemiological methodologies report the following data:
- Male ~2.4%: 1 in 42
- Female ~0.6%: 1 of 167

These values are considered reliable as long as they are supplemented with data on life expectancy and overall mortality. - Source: airc.co.uk, register-tumors.co.uk, en.wikipedia.org

1. Competitive mortality: many people die of other causes before reaching high-risk situations.
2.Time- and age-varying rates: risk increases with age, but does not remain constant.
3.Epidemiological methodologies: AIRTUM/AIOPM estimates integrate demographic factors and overall mortality, providing a realistic-cumulative view.
