Just had a read of that article too. Only problem is that that kind of sense and rationality doesn't necessarily get people to act. A colleague of mine drank heavily (I mean a lot!), smoked heavily, was overweight and had had a heart attack but the cancer diagnosis still came as shock to him and his family. So many people pin their faith on the magic cure (kale!!) or the one true cause. Cancer is sometimes a cumulative reaction as many health problems are. Even if your cancer is pure bad luck (ie something we don't know about yet and may not be able to avoid) as current research indicates, not also being overweight, heart and lung challenged or otherwise unfit will help in dealing with treatment and recovery. Just as long as we realise that keeping healthy isn't the perfect armour either!! But you'll feel better!
