D09: Carcinoma in situ of other and unspecified sites

D09.0: Carcinoma in situ: Bladder

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 bladder. The bladder sits low down in the abdomen and collects the urine. The urine is produced in the two kidneys. The urine flows from the kidneys into the bladder via the ureters. When you pass water, the urine flows from the bladder via the urethra and out.
