Male and female rates of bladder cancer in NI were among the lowest of the 21 developed countries examined, with RoI also having a comparatively low incidence in men but not women (Figure 11.2). Female rates were much lower overall than male rates, and varied somewhat less. Spain had the highest rate of bladder cancer among men, while Denmark had the highest rate among women. However, caution needs to be exercised in making international comparisons of bladder cancer incidence, as classification of the disease with regard to malignant and non-malignant cancers is not consistent across countries.
