At the American Cancer Society, we know that our most effective weapon in the fight against cancer is information .... information to help prevent, diagnose, and treat. That is why it is one of our primary goals to provide the most accurate, up-to-date information about cancer. It is for these purposes that the American Cancer Society has created C-Tools 2.0, a timesaving PDA tool that will provide you with instant access to the most recent cancer information, and it’s available free of charge to anyone in the health care field
