When there is abnormal growth of tissue, then this is also referred to as a tumor. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant. The tumor you have is benign. Benign tumors do not destroy the healthy tissue and do not spread throughout the body.

The large intestine (colon) is like an upside down U in the abdomen. The first part lies in the lower right corner of the abdomen. Then it continues upwards and runs across from right to left. Then it descends again. There then follows an S-shaped part located on the bottom left side of the abdomen, which then merges into the rectum. The rectum is the last section of the large intestine (colon).

You have abnormal growth of tissue in the first part of the large intestine (colon).
