ON THIS PAGE: You will find information about how many people are diagnosed with this type of tumor each year. You will also learn some general information on surviving the disease. To see other pages, use the menu on the side of your screen.
Each year an estimated 8,000 people in the United States are diagnosed with a neuroendocrine tumor that starts in the gastrointestinal tract, which includes the stomach, intestine, appendix, colon, or rectum. Most cases are diagnosed in people who are in their early 60s.
The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate of people with neuroendocrine tumors varies and depends on several factors, including where the tumor is located. Check the section for the specific type of neuroendocrine tumor (see the Overview  section) for more information.
More than 1,500 people in the United States are diagnosed with Merkel cell cancer each year. The 5-year survival rate of people with Merkel cell cancer is about 60%. It is much higher if the cancer is found early, before it has spread to the lymph nodes or distant parts of the body.
It is important to remember that statistics on how many people survive this type of cancer are an estimate. The estimate comes from data based on thousands of people with this cancer in the United States each year. So, your own risk may be different. Doctors cannot say for sure how long anyone will live with a neuroendocrine tumor. Also, experts measure the survival statistics every 5 years. This means that the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Learn more about understanding statistics .
