unfortunately a lot of stuff that we do etc will increase our risks of cancer. just being alive and growing old is a very big cause. whether we live a 'safe' life or not, chances are if we live long enough we'll get cancer or something else wrong with us (although there's plenty of people out there perfectly fit at 80+ yrs).
i think its good for the press to highlight issues, but i am concerned at how they present their stories and at times it does seem to be scaremongering. but then again the more startling the news the more people will read it.
