Cervical Cancer Stages
Published on Jan 29 2010, in the categories: Uncategorized
Cervical cancer is a disease that involves the transformation of normal cells into malign cells (in the cervical texture). The cervix is the lowest and the narrowest part of the uterus. The uterus is an organ situated in the pelvic cavity, having the shape of a pear and in which the foetus incubates. The connection between uterus and vagina is made by the cervix.
After the cancer is tracked down, some investigations must be performed in order to find out if the cancerous cells are diffused into the cervix or into another part of the body. The information gathered after the investigation decides the stadium of the disease. There are five cervical cancer stages: stage zero, first stage, second stage, third stage and fourth stage.
Stage zero is also called “carcinoma in situ” – the tumour’s cells are detected only in the first cellular stratum of the cervix and they did not reach the profound stratums.
The first stage is limited only by the cervix and it is divided in two stages I-A and I-B, based on the quantity of the malign texture. For the stage I-A we can find in the cervix only o very little part of cancerous texture that can be microscopically observed. The cancer doesn’t invade the texture more than 5 millimeters in depth and 7 millimeters in surface. For the stage I-B the cancer is localized and it can be only microscopically observed and it is deeper than 5 millimeters and more diffused than 7 millimeters (in surface) or it can be observed without using a microscope and it can be larger than 4 centimeters.
In the case of the second stage, the disease is diffused outside the cervix, but not in the texture of the pelvis. This stage is split into another two stages: stage II-A (the cancer diffuses outside the cervix until it reaches two superior thirds of the vagina, but not the texture of the uterus) and stage II-B (the tumour diffuses outside the cervix until it reaches two superior thirds of the vagina and the texture around the uterus).
In the third stage the illness infests the inferior third of the vagina and it can infest the texture of the pelvis and the lymphatic nodules around. Again, we have stage III-A (the cancer infested the inferior third of the vagina, but not the texture of the pelvis) and stage III-B (the malign cells are diffused into the texture of the pelvis and/or the cancerous formation is as big as it can block the ducts that make the connection between kidneys and the urinary bladder; this blockings may lead to the growth of the kidneys or even to the interruption of their activity; the malign cells can infest the lymphatic nodules from the pelvis).
During the fourth stage the cancer infests the urinary bladder, the rectum or other parts of the human body. We have also stage IV-A (the illness infested the urinary bladder or the texture of the rectum or the lymphatic nodules) and stage IV-B (the tumour diffused outside de pelvis and the lymphatic nodules into another parts of the body, like the abdomen, the liver, the intestinal tract or the lungs).
For a person who has this tumour it is useful to investigate the cervical cancer stages because it is very important to establish the cancer’s stadium for the planning of the correct treatment.
