Gynecologic Oncology Surgery

What Are Gynecologic Cancers?

Gynecologic cancers form an important group of diseases encompassing the types of cancer that develop in the organs of the female reproductive system. These cancers can arise in different areas such as the uterus, cervix, ovaries, vagina, and vulva, and each follows its own course with different symptoms and treatment processes.

Gynecologic cancers often may not produce symptoms at an early stage. For this reason, regular check-ups and early diagnosis are of great importance for detecting the disease before it progresses. In cases diagnosed early, the treatment process can generally be managed more effectively.

Among these cancer types, the most common are cervical cancer, uterine (endometrial) cancer, and ovarian cancer. Certain viruses, hormonal changes, and genetic factors in particular can play a role in the development of these diseases.

In the treatment of gynecologic cancers, different methods are applied according to the type of disease, its stage, and the patient’s general health condition. Surgical treatment, chemotherapy, and radiotherapy are among the most frequently used treatment options.

Because the female reproductive system is hormone-sensitive and has a complex structure, cancers developing in this region generally arise as cellular changes progress over time. Recognizing these changes at an early stage allows the treatment process to be managed more effectively.

In some cases, gynecologic cancers may progress without symptoms. In later stages, however, symptoms such as abnormal vaginal bleeding, groin or lower abdominal pain, a feeling of bloating, and weight loss may appear. Certain infections can also play an important role in the development of these cancer types; HPV infection in particular is strongly associated with cervical cancer.

What Are the Types of Gynecologic Cancer?

Gynecologic cancers can develop in different parts of the female reproductive system. Each cancer type is evaluated with different symptoms and treatment approaches.

• Cervical cancer: Most often associated with HPV infection. It may not cause symptoms at an early stage, but abnormal bleeding and discharge may be seen in later periods.
• Uterine (endometrial) cancer: Develops in the inner layer of the uterus (endometrium). It usually presents with postmenopausal bleeding and has a high chance of being diagnosed early.
• Ovarian cancer: Usually produces symptoms late. It may present with symptoms such as bloating, abdominal pain, and loss of appetite.
• Vaginal cancer: A rare cancer type developing in the vaginal tissue; it usually occurs at advanced ages.
• Vulvar cancer: Develops in the external genital area (vulva). It may present with symptoms such as itching, sores, and tenderness.

Although each gynecologic cancer has different risk factors, early diagnosis and regular check-ups are of great importance for all cancer types.

Why Do Gynecologic Cancers Occur?

There is no single cause behind the development of gynecologic cancers. Uncontrolled cell proliferation usually begins with a combination of genetic, hormonal, and environmental factors, and cancer may develop over time. The most common causes:

• HPV infection: One of the most important causes of cervical cancer in particular. Certain high-risk types of the HPV virus can lead to changes in cells and, over time, cause cancer to develop.
• Genetic factors: The risk may be increased in individuals with a family history of gynecologic cancer.
• Hormonal imbalances: Long-term hormonal changes, especially increases in estrogen levels, can trigger the development of some cancer types.
• Lifestyle factors: Factors such as smoking, unhealthy diet, obesity, and a sedentary lifestyle can increase cancer risk.
• Age factor: Gynecologic cancers are generally more common at advanced ages. However, some types can also occur at younger ages.

What Are the Symptoms of Gynecologic Cancer?

Gynecologic cancers may not produce symptoms at an early stage. As the disease progresses, however, some important symptoms may appear:

• Abnormal vaginal bleeding (outside the menstrual period or after menopause)
• Groin and lower abdominal pain
• Bloating and a feeling of fullness in the abdomen
• Unexplained weight loss
• Abnormal vaginal discharge

These symptoms do not always mean cancer. However, complaints that persist for a long time or are unusual should definitely be evaluated. Some symptoms can also be confused with gynecological infections; therefore, a detailed examination is necessary for an accurate diagnosis.

How Are Gynecologic Cancers Diagnosed and Staged?

The diagnosis of gynecologic cancers is made by evaluating the patient’s complaints, examination findings, and the tests performed together. Diagnostic methods:

• Gynecological examination: The first stage of evaluation
• Ultrasonography: Allows examination of the uterus and ovaries
• Smear test: Detects cellular changes in the cervix
• Biopsy: A sample is taken from suspicious tissue to establish a definitive diagnosis
• Advanced imaging methods when necessary

Staging is the evaluation performed to determine how far the cancer has spread in the body. Whether the cancer is confined to its original site, has spread to nearby tissues, or has metastasized to distant organs is determined during this process. Staging plays a critical role in forming the treatment plan; in cancers detected at an early stage, treatment options are generally broader.

What Are the Treatment Methods for Gynecologic Cancer?

The treatment of gynecologic cancers is planned according to the type of cancer, its stage, and the patient’s general health condition.

1. Surgical treatment: The most fundamental treatment method, performed to remove the cancerous tissue.
2. Chemotherapy: Drug treatment is applied to destroy cancer cells.
3. Radiotherapy: The aim is to destroy cancer cells with high-energy rays.

These treatment methods can often be applied together. The treatment plan is determined individually for each patient.

Surgical approaches — open and minimally invasive methods: The fundamental aim in oncologic surgery is to leave no cancerous cells behind. To this end, different surgical methods are used according to the type and stage of the disease:

• Open surgery (laparotomy): Provides a wide field of view for completely clearing the tumor and performing detailed staging, especially in advanced-stage or widely spread cancers such as ovarian cancer.
• Laparoscopic (closed) surgery: In the treatment of early-stage uterine or cervical cancers, it can be used for minimally invasive staging and surgical clearance (hysterectomy and lymph node removal). This method offers faster recovery.

The aim in gynecologic oncology surgery is the complete removal of cancerous tissue, bringing the spread of the disease under control, and supporting the patient’s survival and quality of life. This field is a process requiring experience and expertise.

The Importance of Early Diagnosis and Risk Factors

In gynecologic cancers, early diagnosis is one of the important factors that directly affects the treatment process. In cancers detected at an early stage, treatment is generally easier to manage and the risk of the disease spreading is lower. For this reason, regular gynecological check-ups and screening tests should not be neglected.

Certain risk factors play an important role in the development of gynecologic cancers. The presence of these factors does not mean the disease will definitely develop; however, it indicates an increased risk. The main risk factors:

• Advanced age
• Family history of cancer (genetic predisposition)
• HPV infection
• Smoking
• Obesity and a sedentary lifestyle
• Long-term hormonal imbalances

Ways to Protect Against Gynecologic Cancers

Although not all gynecologic cancers can be prevented, some measures can help reduce the risk:

• Regular gynecological check-ups should be performed
• HPV vaccination should be considered
• A healthy eating habit should be adopted
• Smoking and alcohol use should be avoided
• Regular exercise should be undertaken

HPV (human papillomavirus) is strongly associated with cervical cancer in particular. Certain high-risk types of HPV can lead to changes in cervical cells and, over time, cause cancer to develop. For this reason, protection against HPV and regular screening tests play an important role in preventing gynecologic cancers.

Do Gynecologic Cancers Affect Fertility?

Gynecologic cancers and the treatments applied may affect fertility in some cases. Surgical interventions, chemotherapy, and radiotherapy in particular can affect reproductive functions. However, in some cancer types caught at an early stage, fertility-preserving treatment options can be considered. This is why early diagnosis is of great importance.

The danger posed by gynecologic cancers varies according to their type and the stage at which they are diagnosed. In general, because ovarian cancer produces symptoms late, it may be diagnosed at a more advanced stage, whereas cervical cancer can be detected through early screening and uterine cancer usually produces early symptoms. For this reason, whether the disease is diagnosed early or late is a decisive factor in its course.
