Cervical Cancer The cervix is the lower part of the uterus, the place where a baby grows during pregnancy. Cervical cancer is caused by a virus called HPV. The virus spreads through sexual contact. Most women's bodies are able to fight HPV infection. But sometimes the virus leads to cancer. You're at higher risk if you smoke, have had many children, use birth control pills for a long time, or have HIV infection.

Understanding Cervical Changes: Next Steps After an Abnormal Screening Test listen. Severely abnormal cells are found on the surface of the cervix. CIN 3 is usually caused by certain types of human papillomavirus (HPV) and is found when a cervical biopsy is done. If not treated, these abnormal cells may become cancer and spread to nearby normal tissue.

- Cervical cancer is caused by a virus called human papillomavirus (HPV). HPV is not the same as human immunodeficiency virus (HIV, which causes AIDS) or herpes simplex virus (HSV, which causes cold sores and genital herpes). Infection with HPV is very common among adults in the United States. In fact, most people will have HPV at some point in their lives.

- None of these increase your risk for cervical cancer and may or may not require treatment. • Atypical squamous cells of undetermined significance are often caused by infection with human papillomavirus (HPV). Persistent genital infection with a high risk type of HPV has been associated with cervical cancer. Your physician may order an additional test on your Pap specimen to look for genetic material (DNA) from HPV. • It is important to follow your clinician’s recommendations regarding follow-up and treatment of ASCUS. Facts about Cervical Cancer • The American Cancer Society predicts that about 12,170 women will be diagnosed with cervical cancer in the U.S. in 2012.

Can I Prevent Cervical Cancer? In this Article. Cervical cancer is one of the few cancers that’s almost totally preventable. It comes down to avoiding human papillomavirus, or HPV, which is sexually transmitted. HPV is the top cause of cervical cancer. But it doesn’t always cause the disease. Many people have HPV and don’t develop cervical cancer. If you’re sexually active, keep up with your doctor appointments. Your Pap or HPV tests can find abnormal cells in your cervix before the cancer starts.

Cervical Cancer Cervical Cancer. Cervical cancer forms in the interior lining of the cervix, the junction of the vagina and uterus. The development of cervical cancer is typically slow, and occurs over a period of years. The progression to cervical cancer begins with the development of precancerous changes in normal cells.

- Certain HPV types are classified as high-risk because they lead to abnormal cell changes and can cause genital cancers: cervical cancer as well as cancer of the vulva, anus, and penis.In fact, researchers say that virtually all cervical cancers -- more than 99% -- are caused by these high-risk HPV viruses.he most common of the high-risk strains of HPV are types 16 and 18, which cause about 70% of all cervical cancers. If the body clears the infection, the cervical cells return to normal.

Pap and HPV Testing Nearly all cases of cervical cancer are caused by infection with oncogenic, or high-risk, types of human papillomavirus, or HPV. There are about 12 high-risk HPV types. Infections with these sexually transmitted viruses also cause most anal cancers; many vaginal, vulvar, and penile cancers; and some oropharyngeal cancers.

Overview Cervical cancer begins when healthy cells acquire a genetic change (mutation) that causes them to turn into abnormal cells. Healthy cells grow and multiply at a set rate, eventually dying at a set time. Cancer cells grow and multiply out of control, and they don't die. The accumulating abnormal cells form a mass (tumor). Cancer cells invade nearby tissues and can break off from a tumor to spread (metastasize) elsewhere in the body. It isn't clear what causes cervical cancer, but it's certain that HPV plays a role. HPV is very common, and most women with the virus never develop cervical cancer. This means other factors — such as your environment or your lifestyle choices — also determine whether you'll develop cervical cancer.

- Certain HPV types are classified as high-risk because they lead to abnormal cell changes and can cause genital cancers: cervical cancer as well as cancer of the vulva, anus, and penis. In fact, researchers say that virtually all cervical cancers -- more than 99% -- are caused by these high-risk HPV viruses.sually, this virus does not cause any symptoms and doesn't cause disease. Often, the body can clear HPV infection on its own within two years or less. Some types of HPV, typically HPV 6 and HPV 11, cause genital warts. The warts are rarely associated with cervical cancers. They are considered low-risk HPV.
