Table of Neoplasms
The code D12.9 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.
Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients
The anus is the opening of the rectum through which stool passes out of your body. Problems with the anus are common. They include hemorrhoids, abscesses, fissures (cracks), and cancer.
You may be embarrassed to talk about your anal troubles. But it is important to let your doctor know, especially if you have pain or bleeding. The more details you can give about your problem, the better your doctor will be able to help you. Treatments vary depending on the particular problem.

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.
Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor.
Treatment often involves surgery. Benign tumors usually don't grow back.
