You probably know that mix of a bloated belly, a bit of pelvic ache, or a few days when nothing in your lower stomach feels quite right. Most women shrug it off and blame food, hormones or stress. For a small group, something else is quietly going on.
Ovarian cancer is a leading cause of cancer death in women. The American Cancer Society says it is often caught late because the early warning signs look so much like everyday complaints.
In its 2026 figures, the ACS estimates about 21,010 American women will be diagnosed with ovarian cancer this year, and about 12,450 will die from the disease.
The signs below are drawn from the ACS, the CDC and the Foundation for Women's Cancer, the patient education foundation affiliated with the Society of Gynecologic Oncology. The key is not any single symptom. It is the pattern.

The four core signs doctors watch most closely
The ACS lists four symptoms that women with ovarian cancer most often report. On their own, each one is common and usually harmless.
1. Persistent bloating. A belly that feels swollen or tight for weeks at a stretch, not just after a big meal or around your period.
2. Pelvic or lower abdominal pain. A dull ache or pressure in the area below your belly button that keeps coming back.
3. Feeling full too quickly or trouble eating. You sit down to a normal meal and feel stuffed after a few bites. This is the symptom most often written off as indigestion.

4. Urinary urgency or frequency. A constant feeling that you need to pee, or going more often than you used to, without a bladder infection to explain it.
Four more signs the ACS lists as possible warnings
Alongside the core four, the ACS points to other symptoms that can also show up with ovarian cancer. On their own they are vague, which is exactly why they get overlooked.
5. Unusual fatigue. A tiredness that does not lift with rest and is not explained by a hard week.
6. Back pain. A nagging lower back pain that does not match a recent strain or workout.

7. Constipation or other bowel changes. New, lasting changes in how often you go or how your stool looks.
8. Period changes or bleeding after menopause. Heavier or irregular bleeding, or any vaginal bleeding after you have gone through menopause. Bleeding after menopause always warrants a doctor visit on its own.
The rule that separates a bad week from a warning sign
What turns these ordinary complaints into a red flag is how often they happen and how long they last. The ACS puts it in plain numbers.
Any of these symptoms happening more than 12 times in a month is a cue to book an appointment, so the cause can be checked and treated if needed.

The CDC uses a different cutoff. Any warning sign that lasts two weeks or longer, and is not normal for you, is worth getting checked.
The Foundation for Women's Cancer suggests that if the symptoms show up on most days for several weeks, the next step is a doctor's visit, ideally with a gynecologist, including a pelvic exam.
The symptoms do not have to be severe. They have to be persistent and a change from what is normal for you.
When to call your doctor
A single bloated afternoon or one off day for your bladder is not a warning sign. The pattern is. Track how often a symptom shows up, how long it has lasted, and whether it feels different from what your body usually does.

If any of the eight signs above have stuck around for more than a couple of weeks, or keep coming back several times a week, make the call. A pelvic exam, a blood test and an ultrasound are the usual next steps, and in many cases they rule the problem out quickly.
