I have an enlarged appendix, should i worry about it, my doctor said that i'm fine?

Enlarged appendix: I don't know what test you had done that said your appendix is large. A CT scan can usually show if is suspicious of anything to be concerned about. Although it's rare, an enlarged appendix can indicate a problem. You could have a mucocele or a benign or malignant tumor such as a carcinoid. Colonoscopy can see the opening of the appendix and if you haven't had one, see a gastroenterologist
