What is cervical cancer and how is it treated?

Cervical cancer, medically known as cervical carcinoma, is a serious yet largely preventable women’s health condition that occurs when cells in the cervix undergo abnormal changes over time and develop into cancer. Today, one of the most important characteristics of cervical cancer is that most cases are associated with persistent high-risk HPV infection, and precancerous cellular changes can be detected early through regular screening. Therefore, cervical cancer is one of the most manageable gynecological cancers in terms of both prevention and early diagnosis. [1][2][3]

“ ”

The greatest advantage in cervical cancer is that it is often preventable. With HPV vaccination, regular screening, and timely intervention, high-risk cellular changes can be detected before cancer develops. [1][2]

What Is Cervical Cancer?

Cervical cancer is a type of cancer that develops in the cervix, the area connecting the vagina to the uterus. In most cases, the process does not begin suddenly; instead, precancerous cellular changes occur first. If these changes are not monitored and treated appropriately, they can progress to cancer over time. For this reason, cervical cancer is among the diseases that can be detected early and prevented through regular screening. [1][2][8]

What Causes Cervical Cancer?

The primary cause of cervical cancer is a persistent infection with high-risk HPV types. HPV is a very common virus, and in most individuals, the infection clears on its own. However, in some cases, the virus can remain in cervical cells for a long time and lead to cellular changes. If left untreated, these changes may develop into cancer over the years. [1][2][3]

What Are the Risk Factors for Cervical Cancer?

Although HPV infection is the main risk factor, not every HPV infection leads to cancer. Other factors may increase the risk. [3][4]

• High-risk HPV infection
• Lack of regular screening
• Smoking
• Conditions that weaken the immune system
• Infections such as HIV or immunosuppressive treatments
• Other sexually transmitted infections
• Sexual behavior that increases exposure to HPV

The key point is that having risk factors does not mean cancer will definitely develop, but it highlights the importance of regular monitoring and screening. [3][4]

What Are the Symptoms of Cervical Cancer?

In early stages, cervical cancer often does not cause symptoms. Therefore, many cases are detected through screening tests before symptoms appear. When symptoms do occur, the most common include abnormal vaginal bleeding, especially after sexual intercourse, unusual vaginal discharge, and pelvic pain. [5][6]

• Bleeding after sexual intercourse
• Irregular bleeding between periods
• Postmenopausal vaginal bleeding
• Foul-smelling or unusual vaginal discharge
• Pelvic pain
• Pain during sexual intercourse
• Changes in urination or bowel habits in advanced stages
• Leg pain or swelling

These symptoms do not always indicate cancer, but persistent or unexplained bleeding or discharge should always be evaluated by a healthcare professional. [5][6]

How Is Cervical Cancer Diagnosed?

The most important step in early detection is regular screening. Pap smear and HPV tests help identify abnormal cellular changes or the presence of high-risk HPV. If abnormalities are detected, further evaluation with colposcopy and biopsy may be performed. [7][8][9]

Pap Smear and HPV Test

The Pap smear helps detect abnormal cell changes in the cervix, while the HPV test identifies high-risk HPV types. These tests do not directly diagnose cancer but are essential in identifying precancerous changes and assessing risk. [8][9]

Colposcopy and Biopsy

If abnormal results are found, the cervix is examined more closely. During colposcopy, the cervix is evaluated using a special magnifying device, and a biopsy may be taken if necessary. A definitive diagnosis is made through biopsy. [7]

Imaging and Staging

After diagnosis, imaging methods such as CT, MRI, and PET scans may be used to determine the extent of the disease and assist in treatment planning. [7][10]

Why Is Staging Important?

Staging determines whether the cancer is confined to the cervix or has spread to surrounding tissues or distant areas. Treatment decisions largely depend on the stage of the disease. Early-stage cancers generally have more treatment options and higher success rates. [1][10]

How Is Cervical Cancer Treated?

Treatment depends on the stage of the disease, tumor size, extent of spread, the patient’s overall health, and in some cases, fertility expectations. In early stages, surgery is often the primary treatment, while in more advanced stages, radiotherapy and chemotherapy are commonly used together. [10][11]

Surgical Treatment

In early-stage cervical cancer, surgery is an important treatment option. Procedures such as LEEP or conization may be used for small and early lesions. In more advanced but still operable cases, more extensive surgical approaches may be required. [10][11]

Radiotherapy and Chemotherapy

In advanced cases or when surgery is not suitable, radiotherapy and often chemotherapy are applied. This combined approach is one of the main treatment strategies for controlling the disease. [10][11]

Post-Treatment Follow-Up

After treatment is completed, regular follow-up is essential. These visits help monitor for recurrence and evaluate any treatment-related effects. Follow-up plans are tailored individually. [10][11]

“ ”

The strongest defense against cervical cancer is not only treatment but also prevention, regular screening, and timely evaluation of suspicious symptoms. [1][2][8]

Can Cervical Cancer Be Prevented?

Yes, to a large extent. HPV vaccination, regular cervical screening, and timely treatment of precancerous lesions are the most effective methods of protection against cervical cancer. In this respect, cervical cancer is one of the cancers with the strongest strategies for both primary prevention and early detection. [1][2][8]

Frequently Asked Questions (FAQ)

• ❓
  Does cervical cancer cause symptoms in early stages?

• ❓
  What is the main cause of cervical cancer?

  The primary cause is persistent infection with high-risk HPV types. [1][2][3]

• ❓
  Why are Pap smear and HPV tests important?

  These tests help detect precancerous changes and HPV-related risks early. [8][9]

• ❓
  Can cervical cancer be prevented?

  Yes. It can largely be prevented through HPV vaccination, regular screening, and early intervention. [1][2][8]

• ❓
  Is bleeding after intercourse an important symptom?

  Yes. While it does not always indicate cancer, it should always be evaluated by a healthcare professional. [5][6]
