Age: Increasing age raises the chance for developing appendix cancer.Medical history: Patients who have a history of certain medical conditions such as atrophic gastritis or pernicious anemia, which affect the stomach’s ability to produce acid, are at greater risk.Family history: Patients who have a family history of appendix cancer or multiple endocrine neoplasia type 1 (MEN1) syndrome are at greater risk of getting appendix cancer.Smoking: Smokers are more likely to develop appendix cancer than nonsmokers.Risk factors for appendix cancer include: However, it is important to note that not all risk factors cause cancer. Risk factors vary from patient to patient. Hyperthermic intraperitoneal chemotherapy (HIPEC).Your surgeon may recommend removing the peritoneum (the lining of the abdomen). Peritonectomy: A peritonectomy might be recommended if cancer has spread beyond the colon and involves other areas of the abdomen.In this surgery, the tumor and surrounding fluid is removed. Cytoreductive surgery: Cytoreductive surgery is often recommended for non-carcinoid tumors (tumors that have spread).A portion of the colon that is next to your appendix is removed during this procedure. Hemicolectomy: A hemicolectomy is typically performed for a carcinoid tumor that is larger than 2 cm.Appendectomy: An appendectomy is the removal of the appendix.The following types of surgeries may be performed: Surgery (the most common treatment for appendix cancer).The following treatments may be considered: Your physician will discuss the best treatment options for you.

Treatment options depend on the type and stage of cancer. The following tests may be used to diagnose appendix cancer: Your physician will consider several factors when diagnosing appendix cancer such as your symptoms, age, medical history and the type of cancer suspected. However, the following symptoms may occur: Symptoms vary from patient to patient and some patients experience no symptoms at all.

They are more aggressive than carcinoid tumors.

Goblet cell carcinomas/adenocarcinoids: These tumors have features of both adenocarcinomas and carcinoids.

Signet ring cell adenocarcinoma is a very rare subset and tends to be more aggressive.

Appendix adenocarcinoma: These tumors begin as cells that line the inside of the appendix and are treated similarly to colorectal cancer.

If these LAMN lesions perforate or rupture, they can result in a rare condition called pseudomyxoma peritonei (PMP).

Mucinous neoplasms: These are generally benign and include appendix mucoceles as well as lesions with precancerous potential such as low-grade mucinous neoplasms (LAMN) of the appendix.

Many people with a carcinoid tumor have it for many years before it is detected.

Carcinoid tumors (commonly referred to as neuroendocrine tumors): A cancerous, rare type of tumor that grows slowly (about half of appendix cancers are carcinoid tumors).

Below are the three types of tumors that can develop in the appendix:
