Esophageal cancer
Esophageal cancer is a malignant growth in the esophagus. Esophageal cancer is relatively rare, however. Symptoms include pain and trouble swallowing. Endoscopy is one way to detect esophageal cancer. A tube is inserted into the esophagus. Suspicious tissue can be removed for biopsy.
There are several treatments for esophageal cancer. Surgery, laser therapy, radiation and chemotherapy can all be used to treat this cancer, depending on the informed choice of the patient and his or her physician.
Gastrointestinal stromal tumor
A very rare gastric tumor can occasionally occur, called a gastrointestinal stromal tumor. These tumors can occur in the stomach, esophagus, and small intestine. Bleeding and trouble swallowing are some of the symptoms. Frequently the tumor is large when it is finally found.
Stomach cancer
Stomach cancer can develop in all parts of the stomach, and spread rapidly to other nearby areas. It is especially bothersome if the cancer spreads to the lymph nodes. Heartburn, pain in the abdomen, nausea, bowel problems, bloating of the stomach, loss of appetite, fatigue, weight loss, and bleeding vomit or in the stool are all possible signs of stomach cancer. Several tests such as the fecal occult blood test are used to diagnose this cancer.
Colorectal cancer
Colorectal cancer is also called bowel cancer. This cancer can occur in the rectum, appendix, and colon. Colorectal cancer is one of the leading forms of cancer, and is one of the causes of cancer death in the Western World. Colonoscopy is the most reliable way to determine if a person has colorectal cancer.
