Problem is, lung cancer rates are increasing all around the globe, so that does not answer anything regarding &quot;are the lung cancer rate in Beijing unusual vs the rest of the world?&quot;.<p>But at least that&#x27;s a start for a proper discussion.<p>And please do not compare a US rate that includes countryside and cities with a city-based rate in China.
