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 and a leading cause of death in United States.

Making healthy choices and taking precautions at home and in the workplace to reduce potentially harmful exposures can help prevent cancer.
