May is National Cancer Research Month, and the American Association for Cancer Research (AACR) would like your help in supporting a global awareness campaign about the importance of cancer research. Thanks to spectacular advances made by cancer research, more than 16.9 million people in the United States and millions more worldwide are cancer survivors who are living with, through, and beyond their disease.

Despite the significant progress that has been made, cancer is a growing public health challenge globally. The immense toll of cancer is felt not only through the number of lives it affects each year, but also through its significant economic impact. Working together, we can defeat cancer.
