Each has different digestive tumor diagnostics. Moreover, even in the case of colorectal cancer, the ability to increase survival of patients studied is very limited. An alternative in the general population to adopt preventive measures that can reduce the risk of various diseases. These measures include changes in lifestyle with low-fat diets rich in fruits and vegetables, with moderate physical activity. This would be achieved in reducing the incidence of colorectal cancer and ischemic heart disease (CHD).
Preventive treatment with drugs is another option. For example, taking aspirin 300 mg daily of halving deaths from colorectal cancer and protects against heart disease and stroke. The protective effect against cancer seems due to inhibition of an enzyme (protein that speeds up chemical reactions) called cyclooxygenase 2 (COX-2), while the prevention of ischemic heart disease and stroke is mediated by inhibition of COX-1.

Pancreatic Cancer In Western countries, this tumor affects only 10 people per 100,000 adults. Current tests for pancreatic cancer (blood tests or imaging) give a 15% false positive results (diagnosed with cancer when in fact there is not). Therefore, if use is extended to the entire population and early diagnosis, 15,000 people would be falsely diagnosed with pancreatic cancer in 10 patients actually had tumors.
It has been argued early diagnosis in very rare cases of familial pancreatic cancer. This would require very invasive investigations and endoscopic pancreatography, and sampling of pancreatic juice. This test causes 3% of inflamed pancreas (pancreatitis), with sometimes serious consequences. Therefore, this program is only experimental. Read the rest of this entry »
The low incidence of stomach cancer in Western countries eliminates the need for studies of early diagnosis. However, in Japan this cancer is 11% of all deaths among adult males. Therefore routine gastroscopy performed the workplace, which has coincided with a reduction in mortality from gastric cancer. It is unknown whether these two facts are related.
Another possibility is the radiology study with barium, in which the patient swallows a contrast fluid vessel and subjected to X-rays to see inside the esophagus and stomach. While it is easiest that endoscopy is less accurate and does not allow biopsies.
There is a close association between gastric infection by a bacterium, Helicobacter pylori, found in 30% of Western populations and stomach cancer. The H pylori has demonstrated its ability to induce disease in experimental models. In addition, bacteria seem to be determinant in the development of duodenal ulcer, so proper diagnosis and treatment may reduce the risk of ulcers and cancer. Read the rest of this entry »
