CIN and HPV
CIN is usually the result of infection by the virus: human papillomavirus | (HPV). HPV is a common virus that can affect the cells of the cervix. It is mainly transmitted through sexual intercourse. Most women who have had sex have the virus at some point in their lives. However, many women in their immune system to clear the virus and they will not know they ever had. The | smears can detect changes in cells of the cervix caused by HPV.
If you smoke, you are more likely to develop squamous cell cancer of the cervix. The researchers have found chemicals that cause cancer (benzyrene) smoke cigarettes in the cervical mucus of women who smoke. They believe that these chemicals damage the cervix. There are cells in the lining of the cervix, called Langerhans cells, which specifically help to fight against the disease. These cells do not work so well in smokers.
A weakened immune system may also allow CIN to develop into cancer. The immune system may be weakened by:
* Poor nutrition
* Infections such as HIV / AIDS.
Many women are aware that sexual intercourse at an early age and having multiple sexual partners may increase the risk of developing cancer of the cervix. It is important to remember that while these factors may increase the chances of contracting the HPV virus, many women who have had only one sexual partner have HPV, and may move to develop precancerous changes of the cervix (CIN ) or cancer of the cervix. There is therefore no reason for you or others think you are to blame for cancer of the cervix.
The long-term use of birth control pills (more than 10 years) may slightly increase the risk of developing cervical cancer, but the benefits of the pill outweigh the risks for most women
