symptoms of colon cancer found during screening?
Colon cancer is a disease characterized by uncontrolled division of abnormal cells in the colon tumor formation in these cells. Despite the presence of polyps in the human colon, the presentation of symptoms of colon cancer at an early stage is very low. In some cases it may also reveal the symptoms. Today, cancer is the second biggest cancer in the United States and the fourthworldwide. The combination of these facts that give rise to the importance of colorectal screening methods to determine the initial stages of colon cancer.
There are a number of screening methods for colon cancer detection. These tests are conducted tests alone or in combination with other cancer of the colon to distinguish from other intestinal diseases. Below is a list of tests and the discoveryprocedures.
Rectal examination
Part of the routine medical examination, digital rectal examination (DRE) to examine the lower rectum for polyp and tumor growth. This test was performed using a lubricated gloved finger inserted into the rectum to feel for abnormal growths. This test is the finding with the ability to detect prostate cancer in men.
Fecal Occult Blood Test (FOBT)
The American Cancer Society recommends FOBT must be doneannually report on sigmoidoscopy. FOBT has been shown statistically more effective than 24% in research of colorectal cancer itself. Currently there are two types of fecal occult blood test is guaiac FOBT and immunochemical FOBT. The guaiac FOBT uses chemical, guaiac that the presence of the protein hemoglobin in blood samples to detect the infection by looking for traces of the sky. Heaven is a part of hemoglobin that contains iron. Immunological FOBT uses antibodies to monitorstools for human hemoglobin. According to studies, when they performed FOBT colorectal deaths annually reduced by about 15 to 35%.
Sigmoidoscopy
Sigmoidoscopy is a test in which an instrument of enlightenment, sigmoidoscope, is integrated into the rectum and lower colon, the area to investigate. Precancerous, cancer and other abnormal growth rates can be determined during the test, and growths can be removed and biopsy. Statistics show that, when done in conjunction with the FOBT, the help with sigmoidoscopy screening about 76% of colon growths between people in their age group was '80-'50.
Colonoscopy
A light colonoscope is a tool used to study the abnormal growth of colon and rectal area. During a colonoscopy, are abnormal growths or polyps can be found, removed and biopsied. areas can be examined by a colonoscopy sigmoidoscopy lost mainly due to the long interval. Before colonscopy was performed thorough cleaning of> Colon was performed and the patient is sedated.
Double contract barium enema (DCBE)
The DCBE is air in the colon and patient data is filled with a solution of barium enema to help the colon to indicate a series of x-rays. For the colonoscopy, DCBE to help discover about 30-50 percent of colorectal cancers. But may miss small polyps, according to research DCBE.
Computed TomographyColonoscopy
such as virtual colonoscopy, the test is performed using an X-ray of the rectum and special equipment to generate images of the colon at various angles. These images are then processed by a computer to an image produced on the farm and show a colon polyp growth and other abnormalities. As the standard colonoscopy, it is necessary that the two points to make a thorough cleaning. Since this test is less invasive, lessuncomfortable and requires sedation.
Despite the presence of these tests, it was reported that approximately 44% of adults in their age group '80-50 had undergone a screening procedure for colon cancer incidence. We should not be afraid of cancer surgery, we must recognize that early detection reduces to cancer survival.
