ON THIS PAGE: You will find information about how many people are diagnosed with appendix cancer each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.
Primary appendix cancer is cancer that starts in the appendix. This is uncommon, accounting for about 0.5% of all tumors that start in the GI tract. Neuroendocrine tumors of the appendix are more common in women.
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 for people with appendix cancer depends on many factors, including the stage of disease at time of diagnosis, type of appendiceal tumor (see Types of Appendix Tumors in the Introduction section), and size.
In appendix neuroendocrine tumors, the 5-year survival is between 25% to 88%, depending on the size of the tumor and where it has grown or spread.
Due to the rare nature of other types of appendix cancer, specific statistics are not available. Talk with your doctor about the factors related to your specific diagnosis.
It is important to remember that statistics on the survival rates for people with appendix cancer are an estimate. The estimate comes from data based on the number of people with this cancer in the United States. Also, experts measure the survival statistics every 5 years. So the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Talk with your doctor if you have any questions about this information. Learn more about understanding statistics.
