Testing for ovarian cancer starts with your doctor, not a home test or screening program
There is no single screening test that catches ovarian cancer early in people without symptoms. Unlike mammograms for breast cancer or colonoscopies for colon cancer, routine ovarian cancer screening is not standard practice. This means most people find out they have ovarian cancer after symptoms appear — bloating, pelvic pain, difficulty eating, or urinary urgency that lasts more than a few weeks.
If you have symptoms or risk factors, your doctor will order tests to investigate. The most common starting point is a pelvic ultrasound, often followed by a blood test called CA-125. If those results raise concern, you may have a CT scan or be referred to a gynecologic oncologist — a surgeon who specializes in cancer of the female reproductive system. The path depends on what your doctor finds and your personal risk.
Key Takeaways
- Ovarian cancer screening is not routine; testing usually begins when you report symptoms or your doctor identifies risk factors during an exam.
- A pelvic ultrasound and CA-125 blood test are the most common first steps, though neither test is definitive on its own.
- If initial tests suggest cancer, your doctor will refer you to a gynecologic oncologist, who may order imaging like CT or MRI before any biopsy.
- A tissue biopsy — removing a small sample to examine under a microscope — is the only way to confirm ovarian cancer, and it usually happens during surgery.
- Your gynecologist or primary care doctor can order initial tests; you do not need a cancer specialist to start the process.
When your doctor orders a pelvic ultrasound
A pelvic ultrasound is usually the first imaging test. It uses sound waves to create a picture of your ovaries, uterus, and surrounding tissue. You lie on an exam table while a technician moves a small probe over your lower abdomen, or sometimes inserts a probe into the vagina for a clearer view. The whole appointment takes 15 to 30 minutes and causes no pain.
The ultrasound shows the size and shape of your ovaries and whether there are cysts or solid masses. A mass does not mean cancer — many ovarian cysts are benign and go away on their own. But if the ultrasound shows a complex cyst (one with both fluid and solid parts) or a solid mass, your doctor will likely order more tests. You will get the results within a few days, usually by phone or at a follow-up visit.
The CA-125 blood test and what the results mean
CA-125 is a protein that your body makes. Cancer cells often produce more of it than normal cells do, so a high CA-125 level can signal ovarian cancer — but it can also signal other conditions like endometriosis, fibroids, or even a normal menstrual cycle. A single CA-125 result does not diagnose or rule out cancer.
Your doctor orders this blood test when an ultrasound shows something unusual, or when you have symptoms that could point to ovarian cancer. The test takes a few minutes at any lab or doctor's office. A normal CA-125 level is generally below 35 units per milliliter, though this varies slightly by lab. If your level is high, your doctor will not assume cancer — they will order imaging or refer you to a specialist to investigate further.
CT and MRI scans when ultrasound findings need clarification
If your ultrasound shows a mass or complex cyst, your doctor may order a CT (computed tomography) scan or MRI (magnetic resonance imaging) to get a clearer picture. A CT scan uses X-rays to create detailed cross-section images of your abdomen and pelvis. An MRI uses magnetic fields instead of radiation. Both take 20 to 45 minutes and are painless, though MRI machines are loud and some people find them claustrophobic.
These scans help your doctor see whether a mass is likely to be cancer, whether it has spread to nearby organs, and whether you need surgery. If the scan suggests cancer, your doctor will refer you to a gynecologic oncologist. If the scan shows something that looks benign, your doctor may recommend watching it with repeat ultrasounds over time instead of surgery.
Seeing a gynecologic oncologist for diagnosis and biopsy
A gynecologic oncologist is a surgeon trained in cancer of the ovaries, uterus, and other reproductive organs. Once your primary doctor or gynecologist suspects ovarian cancer based on imaging and blood work, they will refer you to this specialist. You can ask for a referral to a cancer center affiliated with a major hospital or academic medical center if you have a choice.
The oncologist will review your imaging, blood work, and medical history, then discuss next steps. In most cases, the only way to confirm ovarian cancer is to remove tissue and examine it under a microscope — a biopsy. This usually happens during surgery, not as a separate procedure. The surgeon may remove the ovary, fallopian tube, or a sample of tissue, depending on what they find during the operation. Pathology results come back within one to two weeks after surgery.
Understanding your risk factors and when to talk to your doctor
Some people have a higher risk of ovarian cancer and may benefit from earlier or more frequent screening, though routine screening is still not recommended even for high-risk people. Risk factors include a family history of ovarian or breast cancer, a BRCA1 or BRCA2 gene mutation, a personal history of breast or colon cancer, or certain hereditary cancer syndromes.
If you have any of these risk factors, tell your doctor. They may refer you to genetic counseling to discuss whether genetic testing makes sense for you. They may also recommend more frequent pelvic exams or ultrasounds, or discuss preventive surgery (removing your ovaries) if your risk is very high. These conversations happen with your primary doctor or gynecologist — you do not need a cancer specialist to start exploring your risk.
What happens between tests: managing uncertainty and follow-up
The time between ordering tests and getting results can feel long. Most ultrasounds and blood work results come back within a few days. CT or MRI results may take a week. If your doctor suspects cancer, they will usually schedule a referral to a gynecologic oncologist within one to two weeks. Pathology results after surgery take one to two weeks.
During this waiting period, write down your symptoms and any questions for your doctor. If you have new symptoms or your symptoms worsen, call your doctor — do not wait for a scheduled appointment. If your initial tests show something unclear, ask your doctor what the next step is and when you will hear back. Knowing the timeline helps you plan and reduces some of the anxiety of not knowing.
Frequently Asked Questions
Can I request ovarian cancer screening even if I have no symptoms?
Routine screening is not recommended for people at average risk, even if you ask for it. If you have symptoms or risk factors, your doctor will order tests. If you have a family history of ovarian cancer or a known BRCA mutation, talk to your doctor about whether more frequent monitoring makes sense for your situation.
Does a normal ultrasound and CA-125 mean I don't have ovarian cancer?
Normal results make cancer less likely, but not impossible. Some early ovarian cancers do not show up on ultrasound or raise CA-125 levels. If your symptoms persist, tell your doctor — they may repeat tests or refer you to a specialist even with normal initial results.
What if my doctor finds a cyst on ultrasound — does that mean I have cancer?
Most ovarian cysts are benign and disappear on their own. Your doctor will look at the size, shape, and whether it has solid parts. Simple cysts (fluid-filled) are almost never cancer. Complex cysts need follow-up imaging in a few weeks or months to see if they change. Only a biopsy can confirm cancer.
How long does it take from first symptoms to a diagnosis?
This varies widely. If you see your doctor quickly and imaging shows something concerning, you could have a referral to a gynecologic oncologist within two to three weeks. Surgery and biopsy results may add another two to four weeks. If initial tests are unclear, the timeline stretches longer as your doctor orders repeat imaging.
Do I need insurance to get tested for ovarian cancer?
Your doctor can order tests regardless of insurance status. If you are uninsured, ask your doctor's office about payment plans or sliding-scale fees. Community health centers and hospital financial assistance programs can also help cover the cost of imaging and blood work.
