He may be a smart dude, but this answer is out there:
> "DER SPIEGEL: Cancer is a silent killer that might get diagnosed long after the exposure, when it is too late.
> Lovelock: I've had 10 cancers in the last few years and it hasn't been very bad. They just appear and grow. If you go to a good oncologist nearby, they'll take it out. It's just unfortunate for people who let it happen and it grows and grows until it's inoperable. I mean, nowadays, I think middle class and fairly wealthy people don't die of cancer."
