To most people, birthdays are just a reminder that they're getting older. But at the American Cancer Society, "Happy Birthday" is a victory song, because a world with less cancer is a world with more birthdays. And that's definitely something to celebrate. More than 11 million Americans who have survived cancerââ¬âand countless others who have avoided itââ¬âwill celebrate a birthday this year, thanks to the progress we're making together to help people stay well and get well, to find cures, and fight back.
