Staging of cancer is meant to help the medical practitioner to tell how far it has spread. You will have to go through a series of scans and tests to determine the extent of the pathology. From the results, effective treatment plans can then be put into action. Prostate cancer staging is therefore very important.
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.
Tumors in stage T2 are classified into three categories. The first one is T2a which indicates that only one lobe of the prostate gland is affected. In T2b, more than half of gland is affected and in T2c stage the entire lobe is affected. On the other hand, if the tumor has left the prostate gland to affect the capsule but has not spread further is said to be in stage T3. This stage has two categories. T3a and T3b where the malignancy has reached the capsule and seminal vesicles respectively.
Stage T4 tumors usually have metastasized. The common areas affected include the pelvic cavity, bladder and rectum. The T4 and T3 tumor stages are said to be locally advanced stages. These are the most difficult stages to treat.
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.
When classifying according to the degree of spread, the first stage is M0 which signifies that the tumor is confined just within the pelvis. In M1, the cancer has finally got out of the pelvis. It has sub stages. The first one is the M1a where the lymph nodes next to the pelvis have been affected and M1b means the skeletal system has been affected by the tumor. In M1c, the malignancy has eventually spread to the rest of a body. A couple of factors are considered in doing the staging.
Locally advanced cancer of the prostate is confined to the gland but the metastatic type has spread. The places which are hardly hit are the bones and lymph nodes. However, many a times it reaches other body organs too.
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.
