Irregular Periods: When It Could Be a Sign of Uterine Cancer

Irregular periods are incredibly common—but sometimes, they’re a red flag for something more serious. Over 60,000 women in the U.S. are diagnosed with uterine cancer each year, and one of the earliest warning signs is unexpected changes in your menstrual cycle. So how do you know when an irregular period is just a fluke—or something worth seeing a doctor about?

This guide breaks down what irregular periods can mean, how they connect to uterine cancer, and when to seek care from a women’s health specialist.

1. What Counts as an Irregular Period?

  • Skipping periods for multiple months
  • Heavy bleeding or prolonged periods
  • Spotting between cycles
  • Bleeding after menopause

These changes aren’t always a cause for concern—but if they’re persistent or paired with other symptoms, they could point to something more serious.

2. Uterine Cancer: Warning Signs to Watch For

  • Abnormal bleeding (between periods or post-menopause)
  • Pelvic or lower abdominal pain
  • Unusual vaginal discharge
  • Unexplained weight loss
  • Fatigue or shortness of breath (in advanced stages)
Irregular periods can signal underlying hormonal or reproductive health issues. Sometimes, they’re a warning sign of uterine cancer.

3. Irregular Periods vs. Hormone Imbalance: How to Tell the Difference

While hormonal shifts, stress, or birth control changes can also lead to irregular periods, cancer-related changes are more persistent or severe. A medical evaluation is the only way to know for sure.

4. Risk Factors That Increase Concern

  • Over age 50 or post-menopause
  • Obesity or metabolic issues
  • Long history of menstruation (early puberty or late menopause)
  • Hormone therapy or PCOS
  • Family history of uterine or colon cancer

5. When to See a Doctor About Irregular Periods

If your period is suddenly different, unusually heavy, or doesn’t return to normal after 2–3 cycles, it’s time to talk to your doctor. Postmenopausal bleeding should be checked immediately.
