Methods of diagnosing bowel cancer

Currently, malignant tumor of the intestine incidence ranks second among cancer.The effectiveness of the treatment and the length of life of the patient will depend on the stage of the disease, so it is important to regularly check the bowel cancer.Oncological diseases are most susceptible people after the age of 45 years old, women and men equally.Every 10 years, the incidence rate increases to 10%.For a survey of bowel cancer should consult a doctor.

There are several methods for diagnosis of tumors in the abdominal cavity.These include endoscopic methods of investigation (sigmoidoscopy, colonoscopy), finger method of research, X-ray, ultrasound.Finger study is one of the safest and easiest and methods of diagnosis of colon cancer.This method allows to identify the early stages of tumor in the distal and dete
ct the presence of blood in the lumen of the intestine, and other associated pathology.

Sigmoidoscopy allows you to explore the rectum and lower colon, identify possible tumors, as well as the need to take a biopsy of the suspicious area.With colonoscopy inspect and assess the condition of the inner surface of the colon.This method makes it possible to detect polyps and other pathologies, as well as a biopsy, removal of polyps smaller than 1 mm.Explore the bowel cancer can be using virtual colonoscopy (CT) using X-rays.

in the diagnosis of colon cancer often use X-ray method called "barium enema".Before the start of exposure to the patient make an enema of barium.The product fills the lumen of the intestine, then the X-ray picture is done.Check the bowel cancer can be with ultrasound.With proper preparation and conduct of the study helps to determine tumor size, degree of sprouting in adjacent organs, as well as to identify metastases.

Laboratory studies

for the diagnosis of colon cancer need to perform laboratory tests.By themselves, they do not help diagnose the tumor, however, may indicate some abnormalities in the condition of the intestine.These studies include fecal occult blood test (fecal immunochemical test).When tumors or polyps detected in stool small amount of blood, even if it is not seen visually.In this case, the patient is sent to colonoscopy.

In assessing the overall analysis of the blood draw attention to the number of red blood cells and hemoglobin level.If anemia is detected, the patient should perform a study of the intestine.Blood tests for tumor markers is performed to determine the specific substances that are released into the blood by cancer cells.For a definitive diagnosis of cancer carry out a biopsy.During the procedure, take a sample of tissue neoplasm, which is then tested in the laboratory.
