Most of the times there are no symptoms of appendix cancer until it has progressed and is advanced.
Cancer of the appendix may cause appendicitis or cause the appendix to rupture. Sometimes this is the first symptom of appendix cancer.
A ruptured appendix may cause a very serious condition called peritonitis, which is an infection of the lining of the abdomen and pelvis. A cancerous tumor of the appendix may also “seed” the abdomen with cancer cells. This may cause more cancerous tumors to develop in the abdomen before it is discovered.
Abdominal discomfort and bloating of the abdomen can be signs of advanced appendiceal cancer.
