Ovarian Cancer Blood Test

What is Ovarian Cancer?

Ovarian cancer is a malignant tumor that develops in the ovaries, often detected in advanced stages. It is caused by abnormal cell growth in ovarian tissue, with genetic mutations such as BRCA1 and BRCA2 significantly increasing risk. The CA-125 blood test is the most important biomarker for monitoring ovarian cancer and assessing treatment response.

What causes ovarian cancer?

Ovarian cancer is caused by abnormal cell growth in the ovaries, where cells multiply uncontrollably and form tumors. Genetic mutations play a significant role, with inherited changes in the BRCA1 and BRCA2 genes accounting for about 10-15% of ovarian cancers. Other contributing factors include age (most cases occur after menopause), family history of ovarian or breast cancer, endometriosis, obesity, and never having been pregnant. Hormone replacement therapy and certain fertility treatments may also increase risk.

What is the best test for ovarian cancer?

The CA-125 blood test is the most important biomarker for monitoring ovarian cancer because it detects elevated levels of the CA-125 protein, which is often increased in women with ovarian cancer. This test is particularly valuable for tracking treatment response and detecting cancer recurrence in patients with confirmed ovarian cancer. However, CA-125 alone cannot diagnose ovarian cancer definitively, as elevated levels can occur in benign conditions like endometriosis, pelvic inflammatory disease, and even during menstruation. For comprehensive evaluation, the CA-125 test is typically used alongside transvaginal ultrasound and pelvic examination. In some cases, additional tumor markers like CA 19-9, CA 15-3, and CA 27.29 may provide supplementary information when used as part of a broader biomarker panel.

When should I get tested for ovarian cancer?

You should get tested if you experience persistent symptoms that last more than two weeks, including bloating, pelvic or abdominal pain, difficulty eating or feeling full quickly, and urinary urgency or frequency. Women with a strong family history of ovarian or breast cancer, especially those with BRCA1 or BRCA2 gene mutations, should discuss regular screening with their healthcare provider. Additionally, consider testing if you have a personal history of breast cancer, endometriosis, or Lynch syndrome, or if you notice unusual changes in your menstrual cycle or unexplained weight loss. Early detection significantly improves treatment outcomes, so do not ignore persistent symptoms that seem unusual for you.

What are the symptoms of ovarian cancer?
Ovarian cancer symptoms often develop gradually and can be vague, making early detection challenging. Common signs include persistent bloating, pelvic or abdominal pain or discomfort, feeling full quickly when eating or loss of appetite, and frequent or urgent need to urinate. You might also notice changes in bowel habits, unexplained weight loss or gain, fatigue, back pain, or abnormal vaginal bleeding. Many women describe a persistent feeling that something is wrong or different with their body. Because these symptoms can mimic common digestive or urinary issues, they are often overlooked, which is why ovarian cancer is frequently diagnosed at advanced stages.
Who is at risk for ovarian cancer?
Women over age 50 are at highest risk, with most cases diagnosed after menopause. Those with inherited genetic mutations, particularly BRCA1 and BRCA2, have a 35-70% lifetime risk of developing ovarian cancer. Family history is significant, especially if a first-degree relative (mother, sister, or daughter) had ovarian or breast cancer. Women with endometriosis, those who have never been pregnant, and individuals with Lynch syndrome or other hereditary cancer syndromes face elevated risk. Additional risk factors include obesity, use of hormone replacement therapy for more than five years, and having had fertility treatments. Conversely, factors like pregnancy, breastfeeding, and use of oral contraceptives can reduce risk.
What happens if ovarian cancer is left untreated?
Untreated ovarian cancer progresses rapidly and spreads beyond the ovaries to other pelvic organs, the abdomen, and eventually distant sites like the liver and lungs. As the cancer advances, you may experience severe abdominal swelling from fluid accumulation (ascites), intense pain, bowel obstruction, and difficulty breathing. The cancer can block the intestines, making eating impossible, and can spread to the liver, causing organ failure. Advanced ovarian cancer significantly reduces quality of life and survival rates drop dramatically once the disease reaches stage III or IV. Without treatment, ovarian cancer is almost always fatal, with average survival measured in months rather than years. Early detection and prompt treatment are critical for the best possible outcomes.
Can ovarian cancer be diagnosed with a blood test?
Blood tests alone cannot definitively diagnose ovarian cancer, but they play an important supporting role in evaluation and monitoring. The CA-125 blood test measures a tumor marker that is elevated in about 80% of women with advanced ovarian cancer, making it useful for assessing suspicious symptoms alongside imaging studies. However, CA-125 levels can also be elevated in benign conditions like endometriosis, fibroids, and pelvic inflammatory disease, which limits its diagnostic accuracy. Definitive diagnosis requires imaging studies such as transvaginal ultrasound or CT scans, followed by surgical biopsy to examine ovarian tissue. Once ovarian cancer is confirmed, CA-125 blood tests become valuable tools for monitoring treatment effectiveness and detecting recurrence.
How is ovarian cancer treated?
Ovarian cancer treatment typically involves a combination of surgery and chemotherapy. Surgery aims to remove as much cancer as possible, which may include removing one or both ovaries, fallopian tubes, the uterus, and affected lymph nodes or surrounding tissue. Following surgery, chemotherapy using drugs like carboplatin and paclitaxel helps destroy remaining cancer cells and reduce recurrence risk. For advanced cases, targeted therapies such as PARP inhibitors (olaparib, niraparib) and bevacizumab may be used, especially in patients with BRCA mutations. Some women may receive chemotherapy before surgery to shrink tumors. Treatment plans are individualized based on cancer stage, type, overall health, and whether you wish to preserve fertility. Regular follow-up with CA-125 testing and imaging is essential for monitoring response and detecting recurrence.
How can I prevent ovarian cancer?
While you cannot completely prevent ovarian cancer, certain strategies significantly reduce risk. Taking oral contraceptives (birth control pills) for five or more years can reduce ovarian cancer risk by up to 50%. Having children and breastfeeding also provide protective benefits. For women with BRCA1 or BRCA2 mutations, prophylactic removal of the ovaries and fallopian tubes after childbearing is complete can reduce risk by 80-90%. Maintaining a healthy weight through balanced diet and regular exercise helps lower risk, as obesity is linked to increased ovarian cancer rates. Avoiding or limiting hormone replacement therapy, particularly long-term use, is advisable. If you have a strong family history, genetic counseling and testing can help you understand your risk and make informed decisions about preventive measures.
What can I do at home to support ovarian health?
While home remedies cannot treat ovarian cancer, certain lifestyle practices support overall ovarian health and may reduce cancer risk. Eating a diet rich in fruits, vegetables, whole grains, and omega-3 fatty acids from fish provides antioxidants that protect cells from damage. Limit red meat and processed foods, which have been linked to increased cancer risk. Regular physical activity, aiming for at least 150 minutes of moderate exercise weekly, helps maintain healthy weight and hormone balance. Avoid smoking and limit alcohol consumption. Managing stress through yoga, meditation, or other relaxation techniques supports immune function. Stay aware of your body and track any persistent changes in symptoms. If you have risk factors, maintain open communication with your healthcare provider about screening options and symptom monitoring.
