The Process Of Prostate Cancer Staging

By Nancy Gardner


Staging of cancer is very important in communicating the features of the disease. There is need for scanning and laboratory tests for the proper diagnosis to be made. Knowing the characteristics of the disease will help the doctors make appropriate treatment decisions. That is why prostate cancer staging is insisted.

The TNM staging system is the commonly accepted technique of staging prostate cancer. It assesses metastases, lymph nodes and tumor separately. T staging comes first. In tumor stage 1, the malignancy cells are so insignificant such that they cannot be picked up by scans or the normal laboratory tests. A needle biopsy has to be done for confirmation purposes.

Stage two in the tumor classification system is divided into three. T2a means half of the prostate gland is affected while in T2b the area affected exceed half. In T3c, the whole of the gland has been invaded by the cancerous cells. In tumor stage 3, the capsule has been broken into by the cancerous cells. This stage also has been subdivided into T3a where the capsule is the only other place which has been affected besides the prostate gland and in T3b, seminal vesicles have been invaded by the cancerous cells.

In tumor stage 4, the malignancy cells have gone on to affect the other regions of the body. The areas which are likely to be affected include the bladder, rectum, pelvic cavity sides and the muscles. The third and fourth stages are the most critical ones.

The lymph nodes will be described to be positive if they have cancerous cells. This makes them enlarge. The degree of enlargement is directly proportional to the number of cancer cells in the lymph node. In NX stage, the nodes can not be checked while in N0 stage, the nodes close to the gland have not been affected. In N1 stage, the lymph nodes have cancerous cells.

In metastasis staging, the first one is Mo where the malignancy has not spread out of pelvis. In M1, the malignancy has reached outside the pelvis. This stage has three subdivisions. In M1a, the cancerous cells have not affected the lymph nodes which are not in the pelvis while in M1b, the malignancy has spread to the bone. Last come M1c in which the cancer has spread to the rest of body organs. There are different things which have to be put into consideration when staging the cancer. Mostly, it is the invasiveness of the disease and its aggressiveness.

Locally advanced type of prostate cancer extends just to the capsule of this gland but the metastasizing type spreads to many of body organs. Mainly, the victims of this spread are the bones and lymph nodes. This is why early detection is stressed to prevent such complications.

Metastasis can occur when the tumor is still in its initial stages. That is why people are advised to regularly go for blood tests and scans for early diagnosis. If some cancerous cells are found in other body organs, immediate action should be taken to control the spread.
