That wasn't the question. If cancer is the deadliest disease, that doesn't mean we can't talk about the obesity epidemic(or vice versa depending on the actual stats, I'm just making a general point).

Imagine if, every time someone wanted to talk about helping end the obesity epidemic, many other people chimed in about how dare you talk about obesity when cancer still exists. And the only way you could make a point about obesity is to put a disclaimer that cancer is totally worse than obesity.
