Cancer is a group of diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer is not just one disease, but many different diseases. There are more than 100 different types of cancer. Cancer is one of the most common chronic diseases in United States. It is second only to heart disease as the leading cause of death.
The Tracking Network is making cancer incidence data easier to access and use. Although cancer incidence data are available on several websites, integrating the information with other health outcome data or environmental data is difficult. Tracking can add to existing public health surveillance of cancer by examining potential ecological relationships with environmental exposures.
