Hi issiphee1 – that sounds like a really simple question to answer doesn’t it, but it actually depends how you group the causes of death together.
About 150,000 people died of cancer in the UK in 2008. If you add all the diseases of the circulatory system together (strokes, heart disease and others) then about 170,000 people died of them in the UK in 2008 – but if you split the diseases of the circulatory system up and count them separately, there were only about 88,000 deaths.
It’s really interesting how questions that sound like they should be easy to answer can sometimes be much more complicated than you think, isn’t it?!
