Cancer does not start overnight. There is gradual change in the tissue until it eventually becomes cancer.
The basic building blocks of our bodies are cells. They come in different forms and shapes. Think of them as bricks, tiles etc. used in the construction of buildings but with a major difference. Cells are alive and can replaced damaged and dying cells. Some cells are constantly deviding to form new cells to replace the older cells. This process of deviding is usually well controlled and only enough new cells are produced to replace the old ones. This process is normally well controlled and only enough to replace the old ones are produced. The is normally a balance between old dying cell and new cells.
In invasive cancer however certain cells start deviding at a fast and uncontrolled rate. It produces new completely abnormal tissue . This new tissue invades and destroy the surrounding normal tissue.
As stated before the cells that will became cancerous do not change overnight. There is a gradually change in the effected cells until they eventually became cancerous. It is posible to diagnose these abnormalities early (before they cause cancer) in some parts of the body. One place where it is posible, is at the mouth of the womb (cervix) . The cervix is a very common place for these abnormalities to develope.
Papsmears are done to diagnosed these changes before cancer develops.
When doing a papsmear cells are scraped from the surface of the mouth of the womb and put on a glass slide. The cells is than send to laboratory to be examined.The presence of precancerous (before cancer) changes can than be diagnosed. Appropriate measures can than be taken to prevent the developepment of cancer if such abnormal cells are diagnosed.
We advise that a papsmear should be taken every twelve months. Where medical insurers or state sponsored organations are involved they usually advise a papsmear once every 36 months. This is due to limited buggets.
Our viewpoint is that every one is responsible for their own health. It is your duty to get the best basic care you can affort. You have only one life . If you can affort it , pay for your yearly examinations. By proper planning more people should be able to affort better medical care. (Refer to "Who is responsible for your health?"
