Quick Answer: What is cervical cancer?
Cervical cancer is a growth of abnormal cells that begins in the cervix, the lower part of the uterus that connects to the vagina. Most cervical cancers are linked to persistent human papillomavirus (HPV) infection, but early cervical cancer may cause no symptoms. Screening, professional evaluation and treatment planning help identify abnormal cells and guide care. [3]
What the research says
HPV-based screening prevented more invasive cancers than cytology alone. A pooled follow-up of four European randomized trials included 176,464 women aged 20 to 64 and recorded 107 invasive cervical cancers over a median of 6.5 years. The rate ratio for invasive cervical carcinoma with HPV-based versus cytology screening was 0.60 (95% CI 0.40 to 0.89), and 0.30 (95% CI 0.15 to 0.60) in women with a negative screening test at entry. The authors concluded that HPV-based screening gives 60% to 70% greater protection (Ronco et al., Lancet, 2014). [1]
HPV vaccination was linked to a much lower risk of invasive cervical cancer. A population-based study of 1,672,983 girls and women aged 10 to 30, followed from 2006 to 2017, found 19 cancers among vaccinated women and 538 among unvaccinated women (cumulative incidence 47 versus 94 per 100,000). The fully adjusted incidence rate ratio was 0.37 (95% CI 0.21 to 0.57): 0.12 (95% CI 0.00 to 0.34) for those vaccinated before age 17 and 0.47 (95% CI 0.27 to 0.75) for those vaccinated at ages 17 to 30 (Lei et al., N Engl J Med, 2020). [2]
What Is Cervical Cancer?
Cervical cancer is a growth of cells that starts in the cervix. The cervix is the lower part of the uterus and connects to the vagina. [3]
Two main types of cells line the surface of the cervix. Squamous cells are thin and flat, while glandular cells have a column-shaped appearance. The area where these cell types meet is where many cervical cancers begin. [3]
The two main types are squamous cell carcinoma, which begins in squamous cells, and adenocarcinoma, which begins in glandular cells lining the cervical canal. [3]
What Causes Cervical Cancer?
Cervical cancer begins when healthy cells in the cervix develop changes in their DNA. These changes can make cells multiply quickly and continue living when healthy cells would normally die. [3]
The extra cells may form a mass called a tumor. Over time, cancer cells can invade nearby tissue and spread to other parts of the body. [3]
Most cervical cancers are linked to HPV. HPV is a common virus passed through sexual contact. In many people, the immune system prevents the virus from causing problems and the infection goes away. In some people, the virus persists and contributes to cell changes that may lead to cancer. [3]
Having HPV does not mean that someone has cervical cancer. A professional test is needed to assess cervical cells.
What Symptoms Can Cervical Cancer Cause?
Cervical cancer may cause no symptoms early on, but as it grows it can cause abnormal vaginal bleeding, unusual discharge, pelvic pain and pain during intercourse. As it grows, possible symptoms include:
Vaginal bleeding after intercourse.
Vaginal bleeding between periods.
Vaginal bleeding after menopause.
Menstrual bleeding that is heavier or lasts longer than usual.
Watery or bloody vaginal discharge that may be heavy or have an odor. [3]
Pelvic pain.
Pain during intercourse.
These symptoms can have causes other than cervical cancer. An online article cannot determine the cause of an individual symptom.
When Should You See a Healthcare Professional?
Make an appointment with a doctor or other healthcare professional if you have symptoms that worry you, especially unusual bleeding, discharge or pelvic pain.
Early cervical cancer may have no symptoms, so do not use the absence of symptoms to decide whether screening is appropriate. Ask your healthcare team which screening options and timing fit your age, history and health needs.
What Are the Risk Factors?
Cervical cancer has several recognized risk factors, though having one does not prove someone will develop the disease.
Risk factor | Why it matters |
Smoking tobacco | Smoking raises cervical cancer risk, and HPV infections may last longer in people who smoke. |
HPV exposure | HPV causes most cervical cancers, and exposure can occur through sexual contact. |
Multiple sexual partners | A greater number of partners for a person or their partner may increase the chance of acquiring HPV. |
Early sexual activity | Sexual activity at an early age may increase the risk of HPV exposure. |
Other sexually transmitted infections | Some infections may increase the risk of HPV, which can lead to cervical cancer. |
Weakened immune system | A weakened immune system may make cervical cancer more likely in people with HPV. |
DES exposure before birth | Exposure to diethylstilbestrol, or DES, during fetal development may increase risk of a rare cervical cancer type. |
A risk factor does not prove that someone will develop cervical cancer. People without a risk factor can still need appropriate screening and evaluation.
How Can You Reduce Your Risk?
You can reduce your cervical cancer risk by asking about HPV vaccination, having routine screening, lowering sexually transmitted infection risk and not smoking. [3]
Ask about HPV vaccination. A healthcare professional can explain whether HPV vaccination is appropriate for you.
Have routine screening. Pap tests can detect precancerous cervical changes that may be monitored or treated before cancer develops. Screening recommendations vary, so discuss timing with your healthcare team. [3]
Reduce sexually transmitted infection risk. Measures may include using condoms and limiting the number of sexual partners. [3]
Do not smoke. If you smoke, ask a healthcare professional about ways to quit.
These steps reduce risk but do not eliminate it. Continue to discuss screening with a qualified healthcare professional.
How Is Cervical Cancer Screened?
Screening can help identify cervical cancer and precancerous cells that may later develop into cancer. [4]
Pap Test
During a Pap test, a healthcare professional collects cells from the cervix. The cells are examined in a laboratory for abnormalities. [4]
A Pap test can detect cancer cells and may also identify precancerous changes. An abnormal result does not by itself mean that a person has cervical cancer. Additional testing may be needed. [4]
HPV DNA Test
An HPV DNA test examines cervical cells for types of HPV that are most likely to lead to cervical cancer. [4]
Ask your healthcare team which screening options are appropriate for you and when they should be repeated. Do not rely on a general article to set your personal screening schedule.
How Is Cervical Cancer Diagnosed?
If cervical cancer is suspected, evaluation may begin with a more thorough examination of the cervix. [4]
Test or procedure | General purpose |
Colposcopy | Uses a magnifying instrument to examine the cervix. |
Punch biopsy | Removes small samples of cervical tissue for laboratory testing. |
Endocervical curettage | Collects tissue from inside the cervical canal. |
LEEP | Uses a thin electrified wire to collect a tissue sample. |
Cone biopsy | Removes a cone-shaped piece of cervical tissue, including deeper layers, for testing. |
Imaging | May help determine the extent of cancer during staging. |
Bladder and rectum examination | May look for signs of cancer in nearby organs during staging. |
The exact tests depend on the screening result, examination and clinical situation.
What Are the Stages of Cervical Cancer?
If cervical cancer is diagnosed, additional tests may be used to determine its extent, also called the stage. [4]
Stages range from 1 to 4. A lower number means that the cancer is limited to the cervix. Higher numbers indicate more advanced disease. Stage 4 may involve nearby organs or spread to other areas. [4]
Staging is based on professional examination and testing. It is not possible to determine a stage from symptoms alone.
How Is Cervical Cancer Treated?
Treatment depends on factors such as the cancer's stage, other health conditions and personal preferences. Options may include surgery, radiation therapy, chemotherapy, targeted therapy, immunotherapy or a combination of treatments. [4]
Treatment | General role |
Surgery | May treat small cancers that have not grown beyond the cervix. |
Radiation therapy | Uses high-powered energy beams and may be external, internal or both. |
Chemotherapy | May be combined with radiation, used before surgery or used to help control symptoms in very advanced cancer. |
Targeted therapy | Uses medicines that attack specific chemicals in cancer cells. |
Immunotherapy | Helps the immune system recognize and attack cancer cells and may be considered in advanced disease. |
Palliative care | Helps relieve pain and other symptoms and can be provided alongside cancer treatment. |
A healthcare team must explain which options apply to a particular person and what benefits, risks and side effects may be involved.
Surgery
Small cervical cancers that have not grown beyond the cervix are often treated with surgery. The size and stage of the cancer, along with future pregnancy preferences, may affect which operation is considered. [4]
Possible procedures include removing the cancer through a cone biopsy, removing the cervix while leaving the uterus, or removing the cervix and uterus through a radical hysterectomy. [4]
Some early cancers may have fertility-sparing options. However, removing the uterus makes pregnancy impossible. Discuss fertility goals before treatment begins. [4]
Radiation Therapy
Radiation therapy uses powerful energy beams to kill cancer cells. It may be given externally, internally through brachytherapy, or through a combination of both. [4]
Radiation is often combined with chemotherapy when cervical cancer has grown beyond the cervix. It may also be used after surgery when there is an increased risk that the cancer could return. [4]
Radiation may cause menopause in people who have not started menopause. Ask the healthcare team about fertility and reproductive-health concerns before treatment. [4]
Chemotherapy
Chemotherapy uses strong medicines to kill cancer cells. Low doses may be combined with radiation therapy, while higher doses may be used in very advanced cancer to help control symptoms. Chemotherapy may also be used before surgery to reduce the size of the cancer. [4]
Targeted Therapy and Immunotherapy
Targeted therapy uses medicines that attack specific chemicals in cancer cells. It may be used with chemotherapy for advanced cervical cancer. [4]
Immunotherapy helps the immune system find and attack cancer cells. It may be considered when cancer is advanced and other treatments are not working. [4]
What Is Palliative Care?
Palliative care is specialized support for people with serious illness. It can help relieve pain and other symptoms and may be provided at the same time as treatments such as surgery, chemotherapy or radiation. [4]
A palliative-care team may include doctors, nurses and other trained professionals. The goal is to improve quality of life for the person with cancer and their family. [4]
Palliative care is not the same as giving up on treatment. It can be an additional layer of support during cancer care.
How can people cope with cervical cancer?
A cancer diagnosis can bring uncertainty, distress and fatigue. Support may make it easier to manage medical decisions and daily life.
Helpful steps may include:
Learn enough about cervical cancer to participate in care decisions.
Write down questions for the healthcare team.
Bring a friend or family member to appointments to take notes.
Ask for help with practical tasks during treatment.
Talk with a trusted person or support group.
Set goals that are realistic and achievable.
Eat well, relax and get enough rest.
It is reasonable to ask for information in plain language and to request more time when a decision feels difficult.
How Can You Prepare for an Appointment?
Ask whether you need to follow any restrictions before an appointment or test.
Bring or write down:
Your symptoms and when they began.
Changes in symptoms over time.
Other health conditions.
Medicines, vitamins and supplements.
Relevant personal or sexual-health history that you feel comfortable discussing.
Whether you have had regular Pap tests or previous abnormal results.
Your questions, listed from most important to least important.
A trusted friend or relative, if helpful.
Questions to ask may include:
What is the most likely cause of my symptoms?
What tests do I need?
What treatments are available?
What side effects could occur?
How might treatment affect fertility or daily activities?
How often will follow-up visits be needed?
