What else causes cancer?

On April 3, 2008, The Salt Lake Tribune published, on page A4, an article headlined: “‘Double whammy’ gene linked to smoking dependency ”. A graphic based on information from the Centers for Disease Control and Prevention (CDC) and the Associated Press accompanied the article. Here’s a scanned image:

    

In words rather than bars, the graph shows:

In industrialized countries, in 2002 there were 0.9 million new cases of tobacco-related cancers among men and 2.7 million other-causes cancers among men. That’s 3 times as many other-causes cases as tobacco-related cancers.

Among women, the numbers are even more startling: 0.3 million tobacco cases; 2.3 million other-causes cases - 8 times as many.

In developing countries, 0.7 million tobacco cases among men; 3.1 million not-tobacco cases - nearly 4.5 times as many.

And among women, 0.1 million tobacco cases; 2.7 million not-tobacco cases - 27 times as many.

That’s many more other-causes cancer cases than tobacco-related ones.

Intriguing:

What does CDC mean by “tobacco-related”? Not “tobacco-caused”? Don’t they know whether tobacco caused these cancers?

A study of cancer patients gives only a correlation, not causation.

Would someone, please, study the “other causes” cases - that significant and neglected majority of new cancers. Or, if there are studies, why is there no coverage in the popular press?

And, by the way, bad nutrition seems causal.
