What are the two proteins that turn off tumor suppressor genes?
Human papillomaviruses (HPV) have two proteins known as E6 and E7 which turn off some tumor suppressor genes, such as p53 and Rb. This may allow the cells lining the cervix to grow too much and to develop changes in additional genes, which in some cases can lead to cancer.
What are the genes that help keep cells growing?
Genes that help keep cell growth under control or make cells die at the right time are called tumor suppressor genes . Cancers can be caused by DNA mutations (gene defects) that turn on oncogenes or turn off tumor suppressor genes.

What causes a lowered immune system?
A lowered immune system can be caused by immune suppression from corticosteroid medications, organ transplantation, treatments for other types of cancer, or from the human immunodeficiency virus (HIV), which is the virus that causes acquired immune deficiency syndrome (AIDS).
What is a risk factor?
A risk factor is anything that increases a person's chance of developing cancer. Although risk factors often influence the development of cancer, most do not directly cause cancer. Some people with several risk factors never develop cancer, while others with no known risk factors do.
Can birth control cause cervical cancer?
Some research studies suggest that oral contraceptives, which are birth control pills, may be associated with an increased risk of cervical cancer and may be associated with higher-risk sexual behavior. However, more research is needed to understand how oral contraceptive use and the development of cervical cancer are connected.
What is the most common cause of cervical cancer?
Human papillomavirus (HPV) infection. Infection by the human papillomavirus (HPV) is the most important risk factor for cervical cancer. HPV is a group of more than 150 related viruses. Some of them cause a type of growth called papillomas, which are more commonly known as warts.
What are the risk factors for cervical cancer?
Risk Factors for Cervical Cancer. A risk factor is anything that increases your chance of getting a disease such as cancer. Different cancers have different risk factors. For example, exposing skin to strong sunlight is a risk factor for skin cancer. Smoking is a risk factor for many cancers.
Why do women have more than 3 full term pregnancies?
Having multiple full-term pregnancies. Women who have had 3 or more full-term pregnancies have an increased risk of developing cervical cancer. It is thought this is probably due to the increased exposure to HPV infection with sexual activity.
How old are women with clear cell adenocarcinoma?
The average age of women diagnosed with DES-related clear-cell adenocarcinoma is 19 years. Since the use of DES during pregnancy was stopped by the FDA in 1971, even the youngest DES daughters are older than 40 − past the age of highest risk.

Women without any of these risk factors rarely develop cervical cancer. Although these risk factors can increase the odds of developing cervical cancer, many women with these risks do not develop this disease.

How long does it take for a cervical cancer to develop?
Research has found that it can take 10 to 20 years, or even longer, for HPV-infected cervical cells to develop into a cancerous tumor.
