What if your body is sending signals, but they’re easy to miss?

That’s often the case with ovarian cancer, one of the most difficult cancers to detect in its early stages. Only about 15% of cases are diagnosed early, when treatment is most effective.

Ovarian cancer doesn’t just affect older women – it can impact women of any age. And because its early symptoms are often subtle, they’re easy to overlook or mistake for something less serious.

That’s why knowing what to look for can be lifesaving. Here are six early warning signs that may point to ovarian cancer – and why it’s important not to ignore them if they stick around.

1. Persistent Abdominal Bloating

Most of us have felt bloated before or during our periods. But if that full, tight, or swollen feeling in your abdomen lasts for more than a few days – especially if it's new or unexplained – it could be more than just routine cycle changes.

Ovarian cancer can cause fluid buildup in the abdomen or pelvis, leading to bloating that doesn’t go away. If your waistband feels snug out of nowhere, or you just don’t feel like yourself, it’s worth paying attention.

2. Constipation or Digestive Changes

New or worsening constipation that doesn’t improve with your usual remedies is one of the more common signs of ovarian cancer.

Other symptoms might include:

  • Upset stomach
  • Diarrhea
  • Gas or changes in your digestion

3. Ongoing Pelvic or Lower Abdominal Pain

We all experience aches and cramps from time to time, but persistent pain in the pelvic area, abdomen, or lower back could be a red flag.


Ovarian tumors can press on nerves and organs in the pelvic region, causing:

  • Continuous pelvic discomfort
  • Lower abdominal pain
  • Pain during sex (if the tumor presses into the vaginal wall)

Pain that won’t go away or gets worse over time deserves attention – don’t write it off.

4. Changes in Bladder Habits

If you suddenly feel like you’re always rushing to the bathroom, or not emptying your bladder fully, it could be more than just hydration or age.

Early ovarian cancer can cause:
  • Frequent urination
  • Sudden urgency
  • Bladder discomfort
This may happen when a tumor presses on your bladder or ureters (the tubes that connect your kidneys to your bladder). If these symptoms last more than a few days, check in with a provider.

5. Difficulty Eating or Feeling Full Quickly

One of the trickier symptoms to spot: feeling full after just a few bites or losing your appetite altogether.

This can be caused by fluid buildup or pressure in the abdomen, making eating feel uncomfortable. Over time, it can lead to:
  • Nausea
  • Energy loss
  • Unintended weight loss

If meals become a struggle – or if you're eating less without trying – it could signal something more serious.

6. Menstrual Irregularities

Though less common, ovarian cancer can cause changes in your menstrual cycle, especially if the tumor is affecting hormone levels or physical structures in the ovaries.

Watch for:
  • Heavier or irregular periods
  • Bleeding between periods
  • Bleeding after menopause

Even if these symptoms don’t seem urgent, track any unusual changes and report them to your doctor.

Other Symptoms to Keep in Mind:

  • Fatigue that doesn’t improve with rest
  • Shortness of breath, especially if it feels new or unexplained

 

When to See a Doctor

Because these symptoms are often vague or mimic less serious conditions, ovarian cancer can go undetected for too long. But trust your instincts – you know your body best.

You should speak to a doctor if:
  • Symptoms last more than two weeks
  • They become more frequent or severe
  • They don’t seem related to another condition
  • Home remedies or over-the-counter options don’t bring relief
