Cervical Cancer Prevention. Most cervical cancers begin in the cells lining the cervix. These cells do not suddenly change into cancer. Instead, the normal cells of the cervix first gradually develop pre-cancerous changes that turn into cancer. Doctors use several terms to describe these pre-cancerous changes, including cervical intraepithelial neoplasia (CIN), squamous intraepithelial lesion (SIL), and dysplasia. These changes can be detected by the Pap test and treated to prevent the development of cancer (see "Can cervical cancer be prevented?").
Cervical cancers and cervical pre-cancers are classified by how they look under a microscope. There are 2 main types of cervical cancers: squamous cell carcinoma and adenocarcinoma. About 80% to 90% of cervical cancers are squamous cell carcinomas. These cancers are from the squamous cells that cover the surface of the exocervix. Under the microscope, this type of cancer is made up of cells that are like squamous cells. Squamous cell carcinomas most often begin where the exocervix joins the endocervix.
Although cervical cancers start from cells with pre-cancerous changes (pre-cancers), only some of the women with pre-cancers of the cervix will develop cancer. The change from cervical pre-cancer to cervical cancer usually takes several years, but it can happen in less than a year. For most women, pre-cancerous cells will go away without any treatment. Still, in some women pre-cancers turn into true (invasive) cancers. Treating all pre-cancers can prevent almost all true cancers. Pre-cancerous changes and specific types of treatment for pre-cancers are discussed in the sections, "How are cervical cancers and pre-cancers diagnosed?" and "Treating pre-cancers and other abnormal Pap test results."
Pre-cancerous changes are separated into different categories based on how the cells of the cervix look under a microscope. These categories are discussed in the section, "How are cervical cancers and pre-cancers diagnosed?"
Although almost all cervical cancers are either squamous cell carcinomas or adenocarcinomas, other types of cancer also can develop in the cervix. These other types, such as melanoma, sarcoma, and lymphoma, occur more commonly in other parts of the body.
Cervical cancers is one of the most preventable types of cancer. Because of the Pap smear test, the number of cervical cancer cases has dropped over the past twenty years. However, many women still develop cervical cancer. In fact, over 9,000 women in the U.S. develop cervical cancer every year.
While some cases of cervical cancer cannot be prevented, there are many things a woman can do to reduce her risk of developing cervical cancer.
5. Follow up on abnormal Pap smears. If you have had an abnormal Pap smear, it is important to follow up with regular Pap smears or colposcopies, whatever your doctor has decided for you. If you have been treated for cervical dysplasia, you still need to follow up with Pap smears or colposcopies. Dysplasia can return and when undetected, can turn into cervical cancer.
6. Get the HPV vaccine. If you are under 27, you may be eligible to receive the HPV vaccine, which prevents high risk strains of HPV in women. The HPV vaccine, Gardasil, was approved by the FDA to give to young girls as young as 9. The vaccine is most effective when given to young women before they become sexually active.
