One day we will all know why cancer occurs but until then we have to live with what we know. And that is that healthy eating, an active body and brain, a reasonable level of happiness and periods of content combine for a better quality of life. I'm no doctor but I'd be prepared to lay bets that something as complex as cancer is the result of multiple trigger points. No life is entirely free of stress - accidents happen, kids get sick, relationships flounder, bosses go weird, parents die. A stress free life may not be possible - it's how we cope with it that may be more important. Sharing loads, delegating, getting time out, prioritising pleasure sometimes, breathing in life rather than just air. Most of us have learned to be better at this - living in and for the moment - since we were diagnosed. That's what we need to encourage in others. Without the over the top wake up call!
