How to prevent colorectal cancer
Modern medicine must be ever more defensive, so it is important to be aware of how to prevent colon cancer, one of the most common cancers in America. Today it is considered that colorectal polyps are precursors of colon cancer. In the United States more than 147,000 cases diagnosed annually.
The polyp is a mass protruding from the lining of the colon or rectum.Polyps of the colon and rectum are usually benign or not cancer cells. There may be one or multiple polyps and they become more common as people age.
Everyone can develop polyps, but the risk is higher in people over 50 years, if you are overweight or smoke, if you have a family history of colon cancer, and if you eat a diet high in fat and no fiber.Over time, certain types of polyps, called adenomatous polyps can become colon cancer. The hairy polyp called an adenoma, also has the risk of becoming malignant. Another common type of polyp found in colon hyperplastic polyp, although this does not turn into cancer.
Polyps larger than 1 cm are at increased risk of cancer than smaller ones. Polyps may also be associated with some inherited disorders.
Typically, polyps are no symptoms, although sometimes they may present with abdominal pain (although rare), blood in the stool or rectal bleeding and fatigue when bleeding resulting in anemia.
It is important to consult your doctor if you see a black stool, fresh blood or notes to evacuate. Sometimes changing the shape and size of fecal material are important data.
The polyps are sometimes found during a rectal exam, the doctor will perform. However, the physical examination is usually normal.
Therefore it is necessary to make radiographs of the colon (barium enema), colonoscopy or flexible sigmoidoscopy, or a new study called virtual colonoscopy (CT combining with an enema).
Over time, adenomatous colorectal polyps can develop into cancer and should be removed (removal). In most cases, the polyps can be removed while performing a colonoscopy. For patients with polyps, colonoscopy should be performed by monitoring every 3 to 5 years to see if the polyps have returned.
Rarely, in cases of polyps with a high potential of becoming cancerous, your doctor may recommend a colectomy (removal of part of the colon).
The prognosis for patients with colorectal polyps is excellent, assuming they are removed. Polyps that are left behind can develop into cancer over time.
I remember that it is important to take measures to prevent polyps and cancer, I suggest increasing your intake of calcium, a diet rich in dairy products, broccoli and salmon. Taking vitamin D, which found in fish, eggs and foods fortified with vitamin D. You should eat fruits, vegetables and cereals. There is a nutrient called lycopene found in tomatoes, fruits and vegetables red, which has an anti-cancerous. Avoid saturated fats and alcohol. You must quit.
With colonoscopy (a test does not require hospitalization and which uses a flexible endoscope), preventing colon cancer by removing polyps before they can become cancer. People over 50 should undergo a colonoscopy, which makes earlier diagnosis and treatment. This can reduce the chances of developing colon cancer or at least help catch at the stage when it is most treatable. People with a family history of polyps or colon cancer may need to be looked at a younger age.
