Once a cancer is metastatic, I guess it's just a question of quality-of-life vs extending-the-time-you-have. Last-ditch chemo is pointless if you have to go anyway. But people who get an operation immediately, then get chemo survive much better than the ones who wait for the tumor to get big and / or metastatic.

You don't want to do what many people do - prevaricate till it's too late, then try the heroic (but sometimes counter-productive) last-ditch measures.

Let's just say: if this causes a few of us to see a doctor earlier, and thus saves a few lives (well, improve the quality and quantity of the days we have left), wouldn't that make it worthwhile?
