What is ovarian cancer and how is it treated?

Ovarian cancer is a serious type of gynecological cancer that affects the female reproductive system and is often detected at a late stage because it usually does not present specific symptoms in its early phases. The ovaries are vital organs responsible for hormone production and egg development. Malignant tumors developing in this area can significantly impact not only reproductive health but also overall quality of life. Although diagnostic and treatment options have improved considerably in recent years, ovarian cancer still remains one of the leading causes of cancer-related deaths among women. Therefore, recognizing symptoms, understanding risk factors, and seeking timely specialist evaluation are of great importance [1][2].

The greatest challenge in ovarian cancer is that symptoms are often subtle and can easily be confused with other conditions. Early evaluation can directly influence treatment success.

What Is Ovarian Cancer?

Ovarian cancer refers to malignant tumors that develop due to the uncontrolled growth of cells in ovarian tissue. These tumors may originate not only from the ovarian surface but also from epithelial tissue, stromal tissue, or germ cells. These differences in cellular origin affect both the biological behavior of the disease and the treatment approach [1][3].

Due to the location of the ovaries within the abdominal cavity, tumors may grow without being noticed until they reach a certain size. Therefore, many cases are diagnosed at advanced stages. However, when detected early, treatment success rates are significantly higher [1][2].

Types of Ovarian Cancer

Ovarian cancer is not a single disease. It is divided into different subtypes based on its cellular origin, and this classification plays a critical role in treatment planning [1][3].

Epithelial Ovarian Cancer

This is the most common type of ovarian cancer. It develops from the epithelial cells covering the outer surface of the ovary and accounts for the majority of cases in adult women. It is the most frequently encountered type in clinical practice [1][3].

Germ Cell Tumors

These tumors arise from germ cells responsible for egg formation. They tend to occur at a younger age and may respond better to treatment in some cases. Their age distribution and biological characteristics differ from epithelial tumors [1][3].

Stromal Tumors

Stromal tumors originate from hormone-producing tissues in the ovary. In some patients, they may present with hormonal symptoms. Although less common, they are important in differential diagnosis [1][3].

Causes and Risk Factors

The exact cause of ovarian cancer is not always clearly defined. However, several risk factors are known to be associated with the disease. Advanced age, particularly the postmenopausal period, is one of the most significant risk factors [1][4].

• Family history of ovarian or breast cancer
• Inherited gene mutations such as BRCA1 and BRCA2
• Advanced age
• Never having given birth
• Early menarche and late menopause
• Endometriosis
• Certain hormonal factors

Family history and genetic predisposition are particularly important. In some cases, genetic counseling and risk assessment may become part of the treatment planning process [1][4][5].

What Are the Symptoms?

Symptoms of ovarian cancer are often non-specific in the early stages and can be confused with digestive or hormonal issues. However, persistent and progressively worsening symptoms should not be ignored [2][6].

• Abdominal bloating or a feeling of fullness
• Indigestion and early satiety
• Pelvic or lower abdominal pain
• Frequent urination
• Changes in bowel habits
• Unexplained weight loss or abdominal enlargement
• Fatigue
• Changes in menstrual cycle or abnormal vaginal bleeding

These symptoms do not necessarily indicate ovarian cancer, but if they persist for several weeks and differ from normal patterns, a gynecological evaluation is recommended [2][6].

How Is Ovarian Cancer Diagnosed?

Diagnosis is based on a combination of medical history, gynecological examination, imaging techniques, and laboratory evaluations. Ultrasound is one of the most commonly used initial diagnostic methods [1][7].

Additional imaging such as CT scans, MRI, and tumor markers may be used when necessary. A definitive diagnosis is usually confirmed through histopathological examination [1][7].

What Is the Role of Tumor Markers?

Tumor markers such as CA-125 can be helpful in diagnosis and follow-up. However, they are not sufficient on their own, as they may be elevated in benign conditions or remain normal in some cancer cases [1][7].

Staging of Ovarian Cancer

After diagnosis, staging is performed to determine the extent of disease spread. This is critical for planning treatment. Early-stage disease may be confined to the ovaries, while advanced stages may involve spread to the peritoneum, lymph nodes, or distant organs [1][3].

The earlier the stage, the better the treatment options and disease control. Therefore, accurate staging is a fundamental part of treatment planning [1][3].

How Is Ovarian Cancer Treated?

Treatment is planned based on tumor type, stage, overall health, age, and reproductive goals. In most cases, surgery and chemotherapy are combined [1][8].

Surgical Treatment

Surgery is a key component of treatment. The goal is to remove as much tumor tissue as possible and accurately determine the stage of the disease [1][8].

In advanced cases, cytoreductive surgery may be performed to reduce tumor burden. The surgical approach is individualized based on the patient’s condition [1][8].

Chemotherapy

Chemotherapy is one of the most commonly used systemic treatments in ovarian cancer. It is usually administered after surgery, although in some cases it may be initiated before surgery to shrink the tumor [1][8].

Targeted Therapies and New Approaches

In recent years, targeted therapies have gained importance. In selected patients, especially those with specific molecular characteristics, treatments such as PARP inhibitors may be included in the treatment plan [1][8].

Side Effects of Treatment

Treatment may lead to side effects such as fatigue, nausea, appetite changes, hair loss, or changes in blood values. However, many of these effects can now be better managed with supportive care [8][9].

Managing side effects is as important as treating the disease itself, as it helps maintain quality of life and treatment adherence [8][9].

Follow-Up and Monitoring After Treatment

Regular follow-up is required after treatment completion. These follow-ups aim to detect recurrence early and evaluate overall health. Follow-up plans are individualized based on disease stage and treatment history [1][9].

Living With Ovarian Cancer and Psychological Support

A diagnosis of ovarian cancer can be challenging not only physically but also psychologically. Anxiety, uncertainty, and difficulties adapting to treatment are common. Therefore, psychological support, family support, and professional counseling when needed should be considered essential parts of care [9].

Successful management of ovarian cancer involves not only treating the tumor but also ensuring comprehensive physical and emotional support for the patient.

Is Prevention Possible?

Complete prevention is not always possible. However, in high-risk groups, genetic counseling, close monitoring, and preventive strategies may be considered. Risk-reducing surgical approaches are typically evaluated only in selected high-risk patients [4][5].

There is currently no standard population-wide screening program for ovarian cancer. Therefore, taking symptoms seriously and seeking specialist evaluation, especially for high-risk individuals, is even more important [5].
