ON THIS PAGE: You will find information about how many people are diagnosed with this type of cancer each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of your screen.
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.
The five-year survival rate is the percentage of people who survive at least five years after the cancer is found. The five-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 Overview section), and size.
In appendix carcinoid tumors, if the tumor size is less than 3 centimeters, without spreading to another part of the body, the five-year survival is about 100%. If the tumor is less than 3 centimeters and has spread to the regional lymph nodes, the five-year survival is 78%. If the tumor is larger than 3 centimeters, with or without spreading to other parts of the body, the five-year survival is also 78%. If the cancer has spread to other parts of the body, the five-year survival rate is 32%. 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.
Cancer survival statistics should be interpreted with caution. It is not possible to tell a person how long he or she will live with appendix cancer. Because the survival statistics are measured in five-year intervals, they may not represent advances made in the treatment or diagnosis of this cancer. Learn more about understanding statistics.
