The appendix is a tube-like organ which is a few centimeters long. It is attached to the beginning of your large intestine, or colon. This is usually below and to the right of your belly button.
Appendectomy is a type of surgery to remove the appendix. Removal of the appendix cures appendicitis. If appendicitis is untreated, it may rupture or burst open and cause very serious illness.
A blockage in the lining of the appendix that results in infection is the likely cause of appendicitis. The bacteria multiply rapidly, causing the appendix to become inflamed, swollen and filled with pus. If not treated promptly, the appendix can rupture.
