Esophogeal Cancer
This is an excerpt from the paper...
The esophagus is a part of the overall digestive tract. It basically is a tube which links the stomach and throat, resting between the trachea and the spine. The adult esophagus is typically ten inches in length on average, and when an individual swallows food the “muscular walls of the esophagus contract to push food down into the stomach. Glands in the lining of the esophagus produce mucus, which keeps the passageway moist and makes swallowing easier” (NIC 2). Like any other organ, the esophagus is comprised of a variety of cell types. In the normal healthy individual, these cells divide only when it is necessary. However, if these cells begin to multiply aside from the normal division they begin to create an excess of tissue. This growing tissue mass is a tumor and can be either benign (non-cancerous) or malignant (cancerous). When a tumor is malignant it poses the fatal threat to the individual. If the cancer is undetected or left untreated, the cancerous cells from the tumors can begin to break away and form in other parts of the body, either by invading tissues and organs near the affected area or by moving to other parts of the body through the lymphatic system. When cancer spreads it is known as metastasis, “Cancer of the esophagus is also called esophageal cancer. It can develop in any part of the esophagus. If the cancer spreads outside the esophagus, it usually shows up ion the nearby lym

eriod of time seem to have a higher risk of developing the disease. Still, many people who have none of the risk factors develop esophageal cancer. This has led some to speculate that the development of the disease could also occur based on genetic makeup. Others theorize it must be from genetic and environmental factors. Nonetheless, perhaps one woman (who get the disease much less frequently than men) who developed esophageal cancer who had no high-risk factors pegged the situation most accurately, “So why do people get cancer? It’s just the luck of the draw!” (Byland Weeks 2). The Mayo Clinic suggests there are seven strategies people should adopt if they wish to reduce their risk of developing any form of cancer: stop smoking, eat right, exercise and control your weight, drink moderately if at all, stay out of bright sun, check with your doctor and get the right tests” (Slovut 3).
PROGNOSIS
Eight out of 100,000 people, mainly male and over the age of fifty, are diagnosed each year with esophageal cancer (Esophageal 1). The prognosis is not optimistic, especially because the disease typically remains undetected in its early stages. The probable outcome is poor, with only a 5 to 10% cure rate (Esophageal 2). D
