I watched the news item on telly last night, they had an 'expert' explaining that 4% of cancers were linked to excessive alcohol consumption, 5% were linked to obesity, and 19% linked to smoking.
So at first sight that means that 72% of cancers aren't linked to anything?
However I then started to wonder about the use of the words 'linked to', these guys choose their words with care and there is a world of difference between 'linked to' and 'caused by'.
My guess is that about 4% of the population are officially alcoholic, 5% obese and 19% smoke, and guess what, they get cancer like the rest of us!
All of this of course ignores one of the big causes of cancer, which is growing old, if only someone would discover the elixir of youth and we could all be 21 again, wouldn't life be wonderful?
