OK, I give up: why do you focus on the least important cause of cancer?

The most important cause of cancer is the number one cause of cancer death, accounting for 30% of all cancer death, and it turns out to be 100% preventable.

And you never even mention it.

I give up: why is your focus so far off?

Especially in an essay where you charge others with that same crime?

The number one cause of cancer death is engineered for addiction, and promoted as sexy and fun, by Philip Morris, R. J. Reynolds, Brown and Williamson, Lorillard, and U.S. Tobacco. It is the most successful consumer product ever sold. It kills one out of five Americans today. It is the largest preventable cause of death in America, and nothing else even comes close. It offers more opportunity for primary prevention than anything else.

If your point is to go after the most important causes of cancer, I agree.

That's why it is striking, amazing, inexplicable, to not even mention the most important cause.
