Ovarian Cancer: Signs and Symptoms

People often call ovarian cancer a silent disease. That is not quite accurate. Most women with ovarian cancer do have symptoms before diagnosis. This is true even in early stages. The real problem is not silence. The symptoms feel like everyday stomach trouble. So they get explained away.

The symptoms doctors watch for most are:

• Bloating or a swollen belly
• Pelvic or belly pain
• Feeling full quickly, even after a small meal
• Needing to urinate often or urgently

Other symptoms can include fatigue, indigestion, back pain, pain during sex, constipation, and a change in your usual period. Unexplained weight loss with belly swelling can also occur. None of these point to ovarian cancer on their own. Each one is far more often caused by something else. That could be irritable bowel syndrome, a urinary tract infection, or normal digestion.

Each symptom alone is unremarkable. So doctors focus on a pattern instead. Three questions matter: Is it new? Is it frequent? Does it persist? One useful marker is symptoms that happen more than about 12 times in a month. That works out to roughly a symptom every other day. Bloating you have had on and off for years is unlikely to fit this pattern. Bloating that started two months ago and has not let up is worth a conversation.

The combination also matters more than any single symptom. Bloating alone is common. It is usually not cancer. Bloating together with pelvic pain and feeling full quickly, all new and all lasting, is a different situation.

Many cancers have a screening test that catches problems before symptoms start. Ovarian cancer does not have one. The U.S. Preventive Services Task Force recommends against screening average-risk women. This applies to blood tests like CA-125 and to transvaginal ultrasound. In large trials, this kind of screening did not reduce deaths. It also led to unnecessary surgery for findings that were not cancer.

This means paying attention to symptoms is the main early-warning system most women have. That is why the pattern above is worth taking seriously, not dismissing.

Screening advice is different for people at high genetic risk. This includes people with a BRCA1 or BRCA2 mutation, or a strong family history of ovarian or breast cancer. If that describes you, ask your doctor about risk-reducing options and closer monitoring. The general advice against screening does not apply the same way to your situation.

See a doctor if you notice bloating, pelvic or belly pain, or feeling full quickly. This matters most when the symptom is new and does not go away within a few weeks. It matters even more with a family history of ovarian or breast cancer, or a known BRCA mutation. You do not need to be certain something is wrong before asking to be checked. Most of the time, these symptoms have a cause other than cancer. Getting checked is what confirms that.

A workup for these symptoms is not the same as a cancer diagnosis. It usually starts with a pelvic exam, where a doctor checks for an enlarged ovary or fluid in the abdomen. A transvaginal ultrasound often follows. This uses sound waves to look at the ovaries and shows whether a mass is solid, fluid-filled, or something else. A blood test called CA-125 may be ordered too. It measures a protein that is often high in ovarian cancer, but many non-cancerous conditions raise it as well, so it is not used alone. If these tests raise concern, a CT or MRI scan may follow, and a biopsy or surgery is the only way to confirm cancer. If a mass looks suspicious, ask to be referred to a gynecologic oncologist before any surgery. That specialist's involvement early on has been linked to better outcomes.

• Given how persistent and new these symptoms are, do they need evaluation?
• What tests would help find the cause — blood work, ultrasound, or both?
• Does my family history of ovarian or breast cancer change how urgently this should be checked?
• If tests are normal but symptoms continue, what happens next?
