When a doctor chooses a method of diagnosing cancer, the general situation is to first perform an imaging examination, and if there is any doubt, then perform a pathological examination to confirm.

Most of the malignant tumors on the appendix are carcinoid. Carcinoid is a kind of gastrointestinal malignant tumor. The tumor is small and grows slowly. The symptoms are usually not obvious and metastasis can occur.

Carcinoids are rare. If the carcinoid tumor secretes peptide amine hormones, the patient will develop symptoms such as abdominal pain, diarrhea, asthma, and hepatomegaly, which is medically called a carcinoid syndrome. This sign rarely occurs in appendicitis. Carcinoids can develop at any age, with an average age of onset of 40 years. Appendiceal carcinoids have a low degree of malignancy, small tumors, mostly less than 2 cm in diameter, and rarely metastasize. Most of the appendix carcinoids grow from the top 1/3 of the appendix, so it is not easy to block the appendix lumen and rarely cause appendicitis. If the carcinoid grows in 1/3 of the appendix, appendicitis usually occurs due to blockage of the lumen.

During the operation, because the tumor is small, it is not easy to find or mistaken for fecal stones. A correct diagnosis can be obtained after pathological examination. Appendicoid carcinoid can also have appendix perforation, which is usually found after surgery.
