The cecum connects the large intestine and the small intestine. While most colorectal cancers arise in the far end of the colon, the rectum and sigmoid colon, the cecum is the next most common site for cancer to arise, according to the Surgical Practice of Northern New Jersey 345. Over 95 percent of colorectal cancer are adenocarcimonas, which often start as polyps, the American Cancer Society explains 34. Symptoms of cecum carcinoma vary from symptoms of other cancers due to the location.
If you are experiencing serious medical symptoms, seek emergency treatment immediately.
Because tumors in the cecum often ulcerate and bleed, anemia, or low hemoglobin levels related to blood loss, can occur as a symptom of cecal carcinoma. Blood loss is occult, meaning not visible with the naked eye, and is diagnosed by testing a small stool sample for minute traces of blood. Anemia can lead to fatigue, weakness and pallor.
Causes of Pain in the Sigmoid Colon
The cecum, a pouchlike structure, lies very close to the appendix. Cecal carcinoma can cause appendicitis or appendicitis-like symptoms in some cases, reports lead author Irene Fiume in the 2006 issue of the World Journal of Emergency Surgery 2. What appears to be appendicitis is actually carcinoma in 1.8 to 8 percent of all cases initially diagnosed as appendicitis, and it occurs more frequently in the elderly. Perforation of the cecal cancer can allow cancer cells to reach and block the opening of the appendix. Appendicitis and subsequent rupture of the appendix can occur from chronic obstruction of the opening of the appendix.

Like other colorectal cancers, carcinoma of the cecum can also cause bowel symptoms. Because the cecum attaches to the small intestine, where stool is mostly liquid, bowel obstruction rarely occurs unless the tumor grows very large.
