Most types of cancer can be put down to bad luck rather than risk factors such as smoking, a study has suggested.
A US team were trying to explain why some tissues were millions of times more vulnerable to cancer than others.
The results, in the journal science, showed two thirds of the cancer types analysed were caused just by chance mutations rather than lifestyle.
However some of the most common and deadly cancers are still heavily influenced by lifestyle.
And Cancer Research UK said a healthy lifestyle would still heavily stack the odds in a person's favour.

As a 28 year old, I've taken an interest in (making a new years resolution like many I suppose) to live a more healthier lifestyle and to look after myself a lot better.
The reason why this prompted me more so is my father only 7 weeks ago has been diagnosed with stage 4 bowel cancer. We have absolutely no history of cancer in our family, so we were in total shock upon hearing the news and the grim statistics for his stage (only 5-10% stage 4 bowel cancer survive 5 or more years after diagnosis). But Cancer research does say that most people who get Bowel Cancer have previously had no family history of it. He's only 56.
However my father is overweight (5'9/10' and 15 stone) and has been like that most of my life, did eat a lot of processed meats, didn't do an awful lot of exercise, did drink 50-100 units of alcohol a week since he was a teenager, smoked till he was 40. All these are risk factors, but did they
cause his cancer?
So of course I've become a neurotic idiot now looking to rapidly change my lifestyle, I'm a teetotaller and I don't smoke anyway and now I want to overhaul my diet as well, but this report suggests most cancers, regardless of if you're healthy or not, are actually down to pure luck, and its making me wonder about what I can really do.
What do you think? Is it actually worth being totally neurotic about health, concentrating on trying to live a lifestyle that reduces your risk of cancer or is it in many ways with the increased worry and stress more counterproductive?
