Only about 10 percent of appendix cancers are colonic-type adenocarcinoma, says Cancer.net. The signet-ring cell adenocarcinoma of the appendix is even less common. It is an aggressive cancer that sometimes begins in the large intestine or the colon and penetrates into the appendix. A hybrid appendix cancer, called goblet cell carcinoma/adenocarcinoid, has the features of both adenocarcinoma and carcinoid cancers. Because it tends to be aggressive, it is treated as an adenocarcinoma.

Symptoms of appendiceal adenocarcinoma include appendicitis, fluid and pain in the abdomen, bloating and pain in the pelvic area, states Cancer.net. Sufferers also sees changes in bowel habits and may become infertile.

Treatment for appendiceal adenocarcinoma involves removing the appendix and as much as half of the right side of the patient's large intestine, claims The Appendix Cancer Connection.
