D01: Carcinoma in situ of other and unspecified digestive organs
D01.2: Carcinoma in situ: Rectum
The tissue in the body is made up of cells. Cancer causes the cells to change, resulting in them multiplying uncontrollably. This leads to a malignant neoplasm (abnormal growth of tissue) developing. This abnormal and excessive tissue growth is called cancer. In your case, the cancer is limited to the skin or mucous membranes. This means that the cancer is very superficial and has not currently extended beyond a certain limit in the tissue. This also means the cancer has not yet been able to spread to other organs. However, the cancer cells can destroy the healthy tissue.
You often don’t get any symptoms with this early form of cancer.
You have an early form of cancer in the inner lining (mucous membrane) of your rectum. Growths on the inner lining of the rectum sometimes form, where this early form of cancer is often found. The last segment of the large intestine consists of 2 sections. These 2 sections are the rectum and anal canal. The feces are collected in the rectum. The feces then move through the short anal canal to the anus. Feces are excreted through the anus.
