What Is Cervical Cancer?
Cervical cancer develops in the cervix, which is the lower part of the uterus that connects to the vagina. It usually starts slowly, often with precancerous changes in the cervical cells before becoming invasive cancer.
Most cervical cancers are linked to long-term infection with high-risk types of human papillomavirus, or HPV. Because of this, cervical cancer is one of the cancers that can often be prevented or caught early through screening and vaccination.
When detected early, treatment is often very effective. That is why regular Pap tests and HPV testing are so important.
Types of Cervical Cancer
The main types include:
-
Squamous cell carcinoma: The most common type, starting in the flat cells covering the cervix.
-
Adenocarcinoma: Begins in the glandular cells of the cervix.
-
Adenosquamous carcinoma: Contains features of both squamous and glandular cells.
-
Rare forms: Less common varieties may need specialised treatment.
Signs and Symptoms of Cervical Cancer
Early cervical cancer may not cause symptoms. As it develops, warning signs may include:
-
Abnormal vaginal bleeding
-
Bleeding after intercourse
-
Bleeding between periods
-
Vaginal discharge that is watery, bloody, or foul-smelling
-
Pelvic pain
-
Pain during sexual intercourse
-
Bleeding after menopause
These symptoms do not always mean cancer, but they should be checked without delay.
Why Does Cervical Cancer Happen?
The most common reason is persistent infection with high-risk HPV. In many people, the immune system clears HPV naturally. But when the infection stays in the body for a long time, it can lead to abnormal cell changes that may progress into cancer.
Risk factors include:
-
HPV infection
-
Early sexual activity
-
Multiple sexual partners
-
Smoking
-
Weak immune system
-
Long-term use of oral contraceptives in some cases
-
Lack of regular screening
-
Having had several full-term pregnancies
Diagnosis of Cervical Cancer
Diagnosis usually starts with screening or symptom evaluation. Common tests include:
-
Pap smear: Checks for abnormal cervical cells.
-
HPV test: Detects high-risk HPV strains linked to cancer.
-
Colposcopy: A close examination of the cervix using a magnifying device.
-
Biopsy: A tissue sample is taken from the cervix for confirmation.
-
Endocervical curettage: A sample is collected from the cervical canal if needed.
-
Imaging tests: MRI, CT, or PET scans may be used to determine the spread.
Finding cervical cancer early can make treatment simpler and outcomes much better.
Treatment Options for Cervical Cancer
Treatment depends on how early the cancer is found and whether it has spread.
-
Surgery: Used for very early-stage disease or to remove affected tissue.
-
Radiation therapy: Often used for more advanced stages.
-
Chemotherapy: May be combined with radiation.
-
Targeted therapy: In some cases, it helps block cancer growth.
-
Immunotherapy: May be recommended for certain advanced cancers.
For precancerous changes, procedures like LEEP or cone biopsy may be enough to remove abnormal cells before cancer develops.
Prevention and Early Detection
Cervical cancer is one of the few cancers that can often be prevented.
-
HPV vaccination: Helps protect against the most dangerous HPV types.
-
Regular Pap and HPV screening: Detects changes before cancer develops.
-
Safe sexual practices: Can reduce HPV exposure.
-
Smoking cessation: Smoking weakens the body’s ability to clear HPV.
Recovery and Follow-Up
After treatment, follow-up care is important to monitor healing and detect recurrence early. Some people may experience changes in fertility, menopause-like symptoms, fatigue, or emotional stress, depending on the treatment received.
Supportive care can include:
-
Regular pelvic examinations
-
Imaging or lab tests when needed
-
Fertility counseling
-
Emotional support
-
Sexual health support
When to Seek Medical Help
You should seek evaluation if you have:
-
Bleeding after sex
-
Unusual vaginal bleeding
-
Persistent pelvic pain
-
Unusual discharge
-
Bleeding after menopause
