Large Intestine Cancer forms in the tissues of the colon. Most colon cancers are adenocarcinomas. When large intestine adenocarcinoma spreads outside the colon or rectum, cancer cells are often found in nearby lymph nodes. Cancer cells may spread to other lymph nodes or organs if cancer cells have reached these nodes. Large intestine adenocarcinoma (cancer) cells are most often applied to the liver.
Large intestine adenocarcinoma (cancer) is more likely to occur as people age. More than 90% of people with this disease are diagnosed after age 50, and the average age at diagnosis is 72.
The following may be used to diagnose the disease:
- Fecal occult blood test (FOBT)
- Sigmoidoscopy
- Colonoscopy
- Double-contrast barium enema
- Digital rectal exam
The following tests and procedures may be used to determine if the Large intestine adenocarcinoma has spread: CT scan, lymph node biopsy, complete blood count, carcinoembryonic antigen (CEA) assay, MRI, and surgery.
Large intestine adenocarcinoma (colon cancer) is the second leading cause of death from cancer in the United States. If the cancer is inoperable or unresectable, radiation or chemotherapy can be used for palliation, but the prognosis is poor.
Inoperable or unresectable large intestine adenocarcinoma may progress locally and cause intestinal obstruction, uncontrolled GI bleeding, and severe pain from invasion into the sacral nerve plexus.
