The malignant tumor of thick and a rectum colon makes the TOP of the most widespread cancers today.
40% of cases of results in lethal outcome within a year. Detection of this disease is not always timely because
the slow growth of a tumor does not cause any symptoms for a long time.The efficiency of treatment will depend
on how timely diagnostics was done and how correctly accurate diagnosis
was given based on the diagnostics results.
What does include diagnostics of cancer?
The first step is consultation with the doctor. Collecting the anamnesis and a rectal palpation are primary exams.
After that additional tests are ordered:
• Irrigoscopy or colonoscopy;
• Ultrasonography (ultrasonography);
• Blood tests, fecal occult blood test, check for tumor markers, scanning.
Irrigoscopyis the x-ray made after filling of intestines with contrast substance.
Colonoscopy is a exam of a large intestine on all its extent with use of the special probe (colonoscope).
During the procedure the extraction of suspicious samples of tissue for histology
or removal of small outgrowths on mucous â€“ polyps are possible.
Colonoscopy is one of the most informative methods of diagnostics at suspicion of intestines cancer.
Biopsyis an important stage at diagnosis of cancer of any kind. It is almost painless procedure
in the course of which the small piece of the changed tissue “is pinched off” from an intestinal
wall for further studying of its character. It is especially ordered to patients who have polyps
as these formations can develop into malignant ones.
Ultrasonographyhelps to estimate spread of a tumor and also presence of metastases in a liver.
But more exact information will be given by MRI of pelvic area or CT of all body.
They give the layer-by-layer image of body thanks to what it is possible to determine the tumor sizes,
its prevalence and educations in other bodies.
Why it is important to undergo full exam?
The described diagnostic methods can show not only cancer of intestines, but also other often met diseases:
• Nonspecific Ulcer Colitis;
• Intestinal impassibility;
• Crohnâ€™s Disease;
• Polyps in intestines which can develop into malignant forms.
And if the first three manifests certain symptoms, then polyps and cancer at the first stages d
o not manifest in any way. It is possible to reveal them only in the course of diagnostics.
Modern methods provide reliability of the obtained data.
How often to check intestines?
According to the recommendations of doctors from Germany, women and men age 50 need
to have intestine check ups every year. Fecal occult blood test should be done annually before 54 years.
n addition, men over 50 years and women over 55 years need to have 2 colonoscopy every 10 years.
The fecal occult blood test should be done every two years.
These recommendations will reduce the risk of development
of new growths or will give the chance to remove them at an early stage.
