What Are the Risk Factors for Cervical Cancer?
Almost all cervical cancers are caused by human papillomavirus (HPV), a common virus that can be passed from one person to another during sex. There are many types of HPV. Some HPV types can cause changes on your cervix that can lead to cervical cancer over time, while other types can cause genital or skin warts.
HPV is so common that most people get it at some time in their lives. HPV usually causes no symptoms so you can’t tell that you have it. For most people, HPV will go away on its own; however, if it does not, there is a chance that over time it may cause cervical cancer.
How to Reduce Risk of Cervical Cancer?
The most important things to help prevent cervical cancer are to get vaccinated against HPV, have regular screening tests, and go back to the doctor if your screening test results are not normal.
Human Papillomavirus (HPV) Vaccine
The HPV vaccine protects against the types of HPV that most often cause cervical, vaginal, and vulvar cancers.
Screening Tests
Two screening tests can help find changes that could become precancer or cervical cancer—
- The Pap test (or Pap smear) looks for precancers, cell changes on the cervix that might become cervical cancer if they are not treated appropriately.
- The HPV test looks for the virus (human papillomavirus) that can cause these cell changes.
What Are the Symptoms of Cervical Cancer?
Early on, cervical cancer may not cause signs and symptoms. Advanced cervical cancer may cause bleeding or discharge from the vagina that is not normal for you, such as bleeding after sex. If you have any of these signs, see your doctor. They may be caused by something other than cancer, but the only way to know is to see your doctor.
What Should I Know About Screening?
- The HPV test looks for the virus (human papillomavirus) that can cause cell changes on the cervix.
- The Pap test (or Pap smear) looks for precancers, cell changes on the cervix that might become cervical cancer if they are not treated appropriately.
Both tests can be done in a doctor’s office or clinic. During the Pap test, the doctor will use a plastic or metal instrument, called a speculum, to look inside your vagina. This helps the doctor examine the vagina and the cervix and collect a few cells and mucus from the cervix and the area around it. The cells are sent to a laboratory.
- If you are getting a Pap test, the cells will be checked to see if they look normal.
- If you are getting an HPV test, the cells will be tested for HPV.
What is cervical precancer?
When there are cervical cells that look abnormal but are not yet cancerous, it is called cervical precancer. These abnormal cells may be the first sign of cancer that develops years later. Cervical precancer usually doesn’t cause pain or other symptoms. It is found with a Pap test.
What Do My Cervical Cancer Screening Test Results Mean?
A Pap test result can be normal, unclear, abnormal, or unsatisfactory. An HPV test result can be positive or negative.
The HPV test and the Pap test are screening tests that can help prevent cervical cancer or find it early.
- The HPV test looks for the virus (human papillomavirus) that can cause cell changes on the cervix.
- The Pap test (or Pap smear) looks for precancers, cell changes on the cervix that might become cervical cancer if they are not treated appropriately.
The Pap test is recommended for everyone with a cervix between the ages of 21 and 65 years old. If you are between 30 and 65 years old, you may choose to get a Pap test only, an HPV test only, or both tests together.
Pap Test Result
A Pap test result can be normal, unclear, abnormal, or unsatisfactory.
Normal
A normal (or “negative”) result means that no cell changes were found on your cervix. This is good news. But you still need to get Pap tests in the future. New cell changes can still form on your cervix.
Your doctor may tell you that you can wait three years for your next screening test if you received a Pap test only. If you also received an HPV test, and the result is negative, your doctor may tell you that you can wait five years for your next screening test.
Unclear (ASC-US)
It is common for test results to come back unclear. Your doctor may use other words to describe this result, like equivocal, inconclusive, or ASC-US. These all mean the same thing—that your cervical cells look like they could be abnormal. It is not clear if it’s related to HPV. It could be related to life changes like pregnancy, menopause, or an infection. The HPV test can help find out if your cell changes are related to HPV. Ask your doctor what to do next.
Abnormal
An abnormal result means that cell changes were found on your cervix. This usually does not mean that you have cervical cancer. Abnormal changes on your cervix are likely caused by HPV. The changes may be minor (low-grade) or serious (high-grade). Most of the time, minor changes go back to normal on their own. But more serious changes can turn into cancer if they are not removed. The more serious changes are often called “precancer” because they are not yet cancer, but they can turn into cancer over time. In rare cases, an abnormal Pap test can show that you may have cancer. You will need other tests to be sure. The earlier you find cervical cancer, the easier it is to treat.
Unsatisfactory
If there are not enough cells in the sample or the cells are clumped together, this is considered unsatisfactory. Your doctor may ask you to come back for another Pap test in a few months.
HPV Test Result
An HPV test result can be positive or negative.
Negative
A negative HPV test means you do not have an HPV type that is linked to cervical cancer. Your doctor may tell you that you can wait five years for your next screening test.
Positive
A positive HPV test means you do have an HPV type that may be linked to cervical cancer. This does not mean you have cervical cancer now. But it could be a warning. The specific HPV type may be identified to determine the next step.
