Is Colon Cancer Caused By Poor Diet Habits?
August 18th, 2008 Posted by: Richard H Ealom
INTRODUCTION: Colon cancer is cancer of the large intestine (colon), the lower part of your digestive system. It is the second leading cause of cancer deaths in the United States, and the leading cause of cancer deaths among non-smokers.
It is, in almost all cases, a treatable disease IF caught early. Truth: When colon cancer is caught early, it has a 95 percent survival rate. It may be nutritionally based. For example, the incidence is much higher in North America than in China, and the Chinese who migrate to North America have a higher incidence.
EARLY: Most colorectal cancers are predictable by early diagnosis and screening. In fact, screening prevents more deaths due to early detection than breast or prostate cancer screening. Other research is looking at multiple genes involved in colon cancer and at improving screening techniques so more cancers can be detected early.
This includes searching for markers in blood, stool or urine that might provide an easier screening tool to early signs of colon cancer. In general, when treated at an early stage, more than 90% of patients survive at least 5 years after their diagnosis. However, only about 39% of colon cancer is found at an early stage.
SYMPTOMS: Symptoms tend to vary depending on the position or site of the cancer within the colon or rectum, though there may not be any symptoms at all. Symptoms of colorectal cancer can include intense abdominal pain, bloody stools or rectal bleeding, unexplained weight loss, or major changes in bowel habits (recurring constipation or diarrhea).
In fact, the most common symptom is no symptoms at all, says Emina Huang, MD. But once these symptoms begin to develop, it may be a sign of more advanced disease. Half of people diagnosed after symptoms develop will die. Finding colorectal cancer before symptoms develop dramatically improves the chance of survival.
CONCLUSION: There is no question that the earlier the cancer is found, the more likely the patient can be cured with surgery. Although the cause is yet unknown, there is evidence that the majority of these cancers arise from polyps (benign intestinal tumors).
It has been well demonstrated that if colorectal cancer is diagnosed in its earliest stages, the cure rate could rise to 90%.
