Colonoscopy is successfully used today to diagnose colon new growths.Based on a number of indications endoscopic investigation allows to get reliable information about the colonic growth surface in order to correctly classify its pattern and take a sample for morphological identification. Yet,colonocsopy does not give an idea of the kind of internal structure the new growth has, nor does it allow to assess the depth of the invasion of the colon wall by a malignant tumor, determine its proliferation to adjacent organs or metastases to regional lymph nodes. Besides, colonocsopy does not provide information about extra intestinal new growths unless they have already permeated the intestinal wall.

    The 3D-NLS using a 4.9 GHz high frequency nonlinear sensor can help clear up all of these issues.

    The 3D-NLS investigation allows to examine intestinal wall layers and the adrectal cellular tissue.
