Members of this group have had, or have, or have known someone, or know someone who has appendix cancer. As with any type of cancer, it is a difficult cancer to have.

Appendiceal cancer is a type of cancer that grows from cells that make up the appendix. The appendix is a small pouch of tissue in the abdomen. It is part of the intestines and colon, which absorb nutrients and remove waste from the body. We do not know what the appendix does, but it may help the immune system.
