Introduction
Cancer of the
colon or
rectum is also called
colorectal cancer. In the United States, colorectal cancer is the fourth most common cancer in men, after skin, prostate, and lung cancer. It is also the fourth most common cancer in women, after skin, lung, and
breast cancer.
This National Cancer Institute (NCI) booklet (NIH Publication No. 03-1552) has important information about the possible causes,
symptoms, diagnosis, and treatment of colorectal cancer. It also has information to help patients cope with the disease.
Scientists are studying colorectal cancer to learn more about it. They are finding out more about its causes and are exploring new ways to prevent, detect, and treat it. This research is increasing our knowledge about colorectal cancer. The NCI provides the most up-to-date information by telephone and on the Internet:
- Telephone (1-800-4-CANCER): Information Specialists at NCI's Cancer Information Service can answer questions about cancer and can send materials published by NCI.
- Internet (http://cancer.gov): Cancer.gov is NCI's Web site. It has a wide range of information that is updated regularly. People can ask questions online and get immediate help through
LiveHelp. Many NCI booklets and fact sheets can be viewed at http://cancer.gov/publications. People in the United States and its territories may use this Web site to order publications. This Web site also explains how people outside the United States can mail or fax their requests for NCI publications.
