Sign on: Tell world leaders to fight the global cancer crisis.

Heads of State:

Right now, you have an opportunity to stop the world's worst killers.

Cancer, diabetes, cardiovascular disease and chronic lung illness are responsible for six out of every ten deaths worldwide. Yet non-communicable diseases (NCDs) have never been a global health priority.

For the first time in history, world leaders are coming together to tackle cancer and other NCDs at the UN Summit this September. Your actions at the summit can put the world's worst killers at the top of the global health agenda.

You have the power to save millions of lives.

That's why I'm calling on you to act with the boldness and urgency that this moment demands. But your leadership cannot stop at making a declaration at the UN Summit in New York City. You need to carry this commitment home and put it into action.

I'm calling on you to seize this once-in-a-lifetime opportunity. And when you do, I pledge to fight by your side every step of the way.

Thank you for your commitment,

Lance Armstrong
