Appendix cancer history and symptoms

The majority of patients with appendix cancer are asymptomatic. Patients may complain of vague abdominal pain or discomfort and/or girdle size changes. However, most of them are presenting with acute appendicitis due to obstruction of the appendix by tumor, or present with malignancy complications like pseudomyxoma peritonei; the rest of diagnosed cases are result of serendipitous finding in imaging studies or discovered during laparotomy or laparoscopy because of cancer complications. The patients complains and presentation is influenced by the tumor histology and stage and ranges from a small asymptomatic adenocarcinoma to a metastatic carcinoid tumor with liver metastasis and carcinoid syndrome signs, symptoms and complications.
