Cervical Cancer: Causes, Symptoms, and Treatment Options
Cervical Cancer: Causes, Symptoms, and Treatment Options
Cervical cancer is one of the most preventable and treatable forms of cancer when detected early. Yet, it remains a leading cause of cancer-related deaths among women globally. Dr. Sachin Trivedi believes in empowering patients with accurate, in-depth knowledge about cervical cancer—from causes and risk factors to symptoms, diagnosis, treatment options, and prevention strategies. This comprehensive guide is designed to answer your most pressing questions with clarity and clinical reliability.
What Is Cervical Cancer?
Cervical cancer is a malignant tumor that forms in the cells of the cervix, the lower part of the uterus that connects to the vagina. It develops slowly over many years, often beginning with precancerous changes in cervical cells known as dysplasia.
Types of Cervical Cancer
Type | Description |
Squamous Cell Carcinoma | Most common form (~70-90% of cases). Originates in the flat, thin cells lining the outer cervix. |
Adenocarcinoma | Begins in gland-producing cells of the cervical canal. Incidence is rising. |
Small Cell Carcinoma & Other Rare Types | Less common and typically more aggressive forms. |
Causes and Risk Factors of Cervical Cancer
The development of cervical cancer is closely linked to persistent infection with high-risk types of human papillomavirus (HPV). However, several additional factors influence the risk.
1. Human Papillomavirus (HPV) Infection
HPV infection is the primary cause of cervical cancer. There are over 100 HPV types, but HPV-16 and HPV-18 are responsible for the majority of cases.
- HPV spreads through sexual contact.
- Many people with HPV infection never develop cancer, as the immune system clears the virus naturally.
2. High-Risk Sexual Behavior
Having multiple sexual partners or early onset of sexual activity increases the likelihood of contracting HPV.
3. Smoking
Cigarette smoke contains carcinogens that affect cervical cells and weaken immune response.
4. Weakened Immune System
Conditions like HIV/AIDS or medications that suppress immunity make it harder for the body to fight HPV.
5. Long-Term Use of Oral Contraceptives
Studies suggest a slight increase in cervical cancer risk with prolonged use of birth control pills, though the benefits often outweigh risks for many women.
6. Other Risk Factors
- Multiple full-term pregnancies
- Young age at first pregnancy
- Low socioeconomic status
- Family history of cervical cancer
Signs and Symptoms of Cervical Cancer
In early stages, cervical cancer may not cause noticeable symptoms. When present, symptoms may include:
Common Symptoms
- Abnormal vaginal bleeding
- After intercourse
- Between periods
- After menopause
- After intercourse
- Unusual vaginal discharge
- Watery, bloody, or foul-smelling
- Watery, bloody, or foul-smelling
- Abnormal vaginal bleeding
- Pelvic or lower back pain
- Pain during intercourse
- Painful or difficult urination
Advanced Symptoms
- Swelling of legs
- Kidney failure
- Severe pelvic pain
- Bone pain
Any persistent or unexplained symptoms should prompt an immediate medical evaluation.
How Cervical Cancer Develops: From Precancer to Invasive Disease
Cervical cancer typically follows a progression:
- HPV infection of cervical cells
- Precancerous changes (CIN)
- CIN – Cervical Intraepithelial Neoplasia
- CIN 1: Mild dysplasia
- CIN 2: Moderate dysplasia
- CIN 3: Severe dysplasia
- CIN 1: Mild dysplasia
- CIN – Cervical Intraepithelial Neoplasia
- Invasive cervical cancer
Early detection of precancerous changes through screening drastically reduces progression to invasive cancer.
Screening and Early Detection
Regular screening is crucial in preventing cervical cancer. The two main screening tests are:
1. Pap Smear (Pap Test)
- Detects abnormal cervical cells.
- Recommended for women aged 21 to 65 every 3 years.
- Detects precancer before it becomes invasive.
2. HPV DNA Test
- Identifies presence of high-risk HPV types.
- Can be done alone or with Pap smear.
- Recommended for women aged 30 to 65 every 5 years (when co-tested with Pap).
Screening Frequency Summary
Age Group | Recommended Screening |
21–29 years | Pap test every 3 years |
30–65 years | Pap + HPV test every 5 years or Pap alone every 3 years |
>65 years | Screening may stop if prior tests were normal |
Diagnosis of Cervical Cancer
If screening indicates abnormal results, further diagnostic procedures may include:
Colposcopy
- A magnified visual examination of the cervix.
- Directed biopsies taken from suspicious areas.
Biopsy
- Tissue sample analyzed to confirm cancer and assess severity.
Imaging Tests
Used to determine cancer spread:
- MRI
- CT scan
- PET scan
Staging of Cervical Cancer
Staging describes how far cancer has spread:
Stage | Description |
Stage I | Cancer confined to cervix |
Stage II | Spread beyond cervix to upper vagina |
Stage III | Spread to lower vagina or pelvic wall |
Stage IV | Spread to bladder, rectum, or distant organs |
Accurate staging is essential for selecting the most effective treatment.
Treatment Options for Cervical Cancer
Treatment depends on cancer stage, overall health, fertility desires, and patient preferences.
1. Surgery
Surgical options may include:
- Conization
Removes a cone-shaped section of abnormal tissue; used for early precancer and microinvasive cancer. - Hysterectomy
Removal of the uterus and cervix. Types include:- Simple hysterectomy
- Radical hysterectomy (also removes surrounding tissues)
- Trachelectomy
Fertility-sparing surgery for early stage in select patients.
2. Radiation Therapy
Radiation uses high-energy rays to destroy cancer cells. It may be used:
- Alone in early stage
- With chemotherapy in advanced stages
- Post-surgery if risk of recurrence is high
3. Chemotherapy
Chemotherapy involves anticancer drugs to kill cancer cells. Often combined with radiation (chemoradiation) for advanced cervical cancer.
4. Targeted Therapy & Immunotherapy
Newer treatments may include:
- Bevacizumab (Avastin) – targets blood vessel growth to cancer.
- Pembrolizumab – immune checkpoint inhibitor that helps the immune system attack cancer.
These are typically considered for recurrent or metastatic disease.
Side Effects of Treatment
Knowing potential side effects helps patients prepare and manage expectations.
Common Side Effects
Treatment | Possible Side Effects |
Surgery | Pain, bleeding, infection, urinary changes |
Radiation | Fatigue, skin irritation, diarrhea, bladder irritation |
Chemotherapy | Nausea, hair loss, low blood counts, fatigue |
Targeted Therapy / Immunotherapy | High blood pressure, immune reactions |
Fertility and Cervical Cancer
Many women diagnosed with early stage cervical cancer worry about fertility.
- Early stages: fertility-preserving surgeries like trachelectomy may be an option.
- Advanced stages: treatments often compromise fertility; fertility counseling is recommended before therapy.
Prevention of Cervical Cancer
Cervical cancer is largely preventable through vaccination and screening.
1. HPV Vaccination
HPV vaccine protects against high-risk HPV types. Ideally given:
- Before sexual activity begins
- Recommended age: 9–14 years (two doses)
- Can be given up to 26–45 years based on individual risk
2. Safe Sexual Practices
- Use of condoms
- Limiting number of sexual partners
3. Regular Screening
Screenings help detect abnormal cells before they progress to cancer.
Cervical Cancer: Myths vs. Facts
- Myth: Cervical cancer always causes symptoms early.
Fact: Early stages often have no symptoms, highlighting the importance of screening.
- Myth: Only promiscuous women get cervical cancer.
Fact: HPV infection can occur with any sexual activity; cervical cancer is not limited to any one lifestyle.
- Myth: HPV always leads to cancer.
Fact: Most HPV infections clear naturally; persistent high-risk types cause cancer.
Frequently Asked Questions (FAQs)
Q: At what age should I start cervical cancer screening?
A: Screening begins at age 21 with a Pap test.
