Ovarian Cancer: Symptoms, Diagnosis, Treatment, and Development Timeline

Ovarian cancer is a serious condition that begins in the ovaries, the female reproductive organs responsible for producing eggs and hormones. Often called the "silent killer," ovarian cancer is challenging to detect early due to subtle symptoms and the lack of effective screening methods for the general population. This blog provides a comprehensive overview of ovarian cancer, highlighting its symptoms, how to check for it at home, available treatment options, and the timeline for its development. 

Ovarian Cancer Symptoms    

Ovarian cancer symptoms often go unnoticed in the early stages, as they can be vague and easily mistaken for other less serious conditions. However, as the disease progresses, the signs may become more apparent. Common symptoms include: 

1. Abdominal and Pelvic Discomfort

• Persistent bloating or a feeling of fullness

• Pain or pressure in the lower abdomen or pelvis

2. Changes in Bowel and Bladder Habits

• Frequent urination or an urgent need to urinate

• Constipation, diarrhea, or other bowel changes

3. Unexplained Weight Changes

• Sudden weight loss or gain, often accompanied by a loss of appetite

4. Menstrual Irregularities

• Abnormal bleeding or spotting, especially post-menopause

5. Fatigue and General Malaise

• Persistent tiredness or low energy levels

6. Other Symptoms

• Back pain

• Nausea or indigestion

• Pain during intercourse

These symptoms may not always indicate ovarian cancer, but if they persist for more than a few weeks or worsen over time, it’s crucial to consult a healthcare provider for further evaluation. 

How to Check for Ovarian Cancer at Home  

While ovarian cancer cannot be diagnosed at home, being aware of your body and recognising unusual changes can help in seeking timely medical advice. Here are some proactive steps you can take: 

1. Track Symptoms

Keep a journal to record any persistent symptoms such as bloating, pelvic pain, or changes in appetite. Note how often they occur and their severity.

2. Monitor Your Menstrual Cycle

Pay attention to irregular bleeding, spotting, or changes in your cycle, especially if you are post-menopausal.

3. Perform a Self-Abdominal Check

Gently press on your lower abdomen to feel for any unusual lumps or swelling. While this is not a definitive test, any unusual mass or pain should prompt a visit to your doctor.

4. Family History Awareness

If you have a family history of ovarian, breast, or colorectal cancer, you may be at a higher risk for developing ovarian cancer. Use this knowledge to discuss genetic testing or regular screening options with your doctor.

5. Healthy Lifestyle Choices

While not a diagnostic tool, maintaining a healthy weight, eating a balanced diet, and avoiding smoking can lower your overall risk.

6. Know When to Seek Medical Advice

If your symptoms persist for more than 2-3 weeks, schedule a visit with a healthcare professional. Early detection is key to successful treatment outcomes.

How Is Ovarian Cancer Treated?  

Treatment for ovarian cancer depends on the stage and type of cancer, as well as the patient’s overall health. The most common treatment approaches, after classification and staging, include surgery, chemotherapy, targeted therapy, and, in some cases, radiation therapy. 

1. Surgery

Surgery is often the first step in treating ovarian cancer. The goal is to remove as much of the cancer as possible. This may involve: 

• Salphingo-oophorectomy: Removal of one or both ovaries and fallopian tubes

• Hysterectomy + salphingo-oophorectomy: Removal of the uterus along with the ovaries and fallopian tubes

• Debulking Surgery: Removing as much of the visible cancer from the abdominal cavity (when the tumor has spread) that may include parts of other intraabdominal organs like the bowels and urinary bladder

2. Chemotherapy

After surgery, chemotherapy is commonly used to kill any remaining cancer cells. It can be administered intravenously or directly into the abdomen (intraperitoneal chemotherapy).

Common drugs include platinum-based agents like cisplatin and carboplatin, often combined with other drugs like paclitaxel and docetaxel (taxanes).

3. Targeted Therapy

Advanced ovarian cancers may be treated with targeted medications that attack specific cancer cells without harming normal cells.

• PARP Inhibitors (e.g., olaparib, niraparib): Effective in patients with BRCA mutations

• Bevacizumab: A drug that prevents the formation of new blood vessels that feed cancer cells

4. Hormone Therapy

Hormone-blocking medications, such as tamoxifen, may be used to treat certain types of ovarian cancer, particularly in cases where surgery or chemotherapy is not suitable.

5. Radiation Therapy

While rarely used for ovarian cancer, radiation therapy may be employed in specific cases to target localised cancer recurrence.

6. Clinical Trials

Patients with advanced or recurrent ovarian cancer may consider participating in clinical trials for experimental treatments, including immunotherapy.

7. Palliative Care

For far advanced stages with nil curative options, palliative care focuses on relieving symptoms, alleviating pain and improving quality of life.

Regular follow-ups and monitoring are crucial after treatment to detect any recurrence or manage side effects of therapy. 

How Long Does Ovarian Cancer Take to Develop? 

Ovarian cancer does not develop overnight; it typically progresses over several years. However, the timeline can vary based on the type of ovarian cancer: 

1. Epithelial Ovarian Cancer

• This is the most common type, accounting for about 90% of ovarian cancer cases. It generally develops slowly, starting as small, localised lesions on the surface of the ovary

• Early-stage epithelial cancer may take years to progress to advanced stages, but due to its subtle symptoms, it is often not detected until later stages

2. Germ Cell Tumours

These are rare and tend to develop more quickly than epithelial types. Germ cell tumours are often diagnosed in younger women and may exhibit symptoms earlier

3. Stromal Tumours

These tumours arise in the ovarian connective tissue and may also grow more slowly. They are sometimes detected earlier due to the production of hormones that cause noticeable symptoms like vaginal bleeding

4. Factors Influencing Development

• Genetic Mutations: Women with BRCA1 or BRCA2 gene mutations may experience faster cancer progression

• Risk Factors: Family history, age, and lifestyle factors can influence how quickly ovarian cancer develops

• Detection and Diagnosis: Without effective early screening tools, the disease often remains hidden until it has spread, shortening the perceived timeline for curative intent of treatment

5. Staging (based on FIGO [International Federation of Gynecology and Obstetrics])

• Stage I: Cancer is confined to the ovaries or fallopian tubes and may take years to progress beyond this stage

• Stage II-III: Cancer begins to spread within the pelvic region, abdomen and lymph nodes. Progression can occur over months to years

• Stage IV: Advanced cancer that spreads to distant organs can develop more rapidly, depending on the individual case

While the exact timeline varies, the key to improving outcomes lies in early detection and prompt treatment. 

Ovarian cancer remains one of the most challenging cancers to detect and treat. By understanding the symptoms, taking proactive steps to monitor your health, and seeking medical advice when needed, you can increase the chances of early detection and successful treatment. Advances in surgery, chemotherapy, and targeted therapies are improving survival rates, but awareness and education about this disease remain crucial. 

If you experience persistent symptoms or have a family history of ovarian or related cancers, consult a healthcare professional for personalised advice and screening options. Early action can save lives.
