Approved by the Cancer.Net Editorial Board, 08/2018

ON THIS PAGE: You will find out more about body changes and other things that can signal a problem that may need medical care. Use the menu to see other pages.

People with appendix cancer may experience the following symptoms or signs. Sometimes, people with appendix cancer do not have any of these changes. Or, the cause of a symptom may be a different medical condition that is not cancer. 

  • Appendicitis

  • Ascites, which is fluid in the abdomen

  • Bloating

  • Pain in the abdomen or pelvis area

  • Increased girth (size of the waistline), with or without a protrusion of the navel (bellybutton)

  • Changes in bowel function

  • Infertility, which is the inability to have a child 

If you are concerned about any changes you experience, please talk with your doctor. Your doctor will ask how long and how often you’ve been experiencing the symptom(s), in addition to other questions. This is to help figure out the cause of the problem, called a diagnosis.

If cancer is diagnosed, relieving symptoms remains an important part of cancer care and treatment. This may be called palliative care or supportive care. Be sure to talk with your health care team about the symptoms you experience, including any new symptoms or a change in symptoms.
