Endometriosis is a chronic disorder in which the endometrium — the tissue that ordinarily lines your uterus — develops outside your uterus. It typically involves other parts of your reproductive system such as the fallopian tubes and ovaries.
The abnormal tissue that grows from endometriosis is not cancerous, but it can cause complications such as:
- tiredness or chronic fatigue
- bowel and urinary problems
- pain or cramping during menstrual periods
- heavier and longer menstrual flow
According to the Endometriosis Foundation of America, endometriosis affects about 200 million women globally.
Studies have sought to determine a potential connection between endometriosis and cancer, and results are mixed.
The European Society for Human Reproduction and Embryology recommends doctors inform women that evidence does not indicate endometriosis causes cancer, though some types of cancer are more common in those experiencing endometriosis.
The researchers suggested those experiencing endometriosis may have an increased risk of endometrial cancer later in life because of both estrogen stimulation and chronic inflammation. However, the cancer was seen in less than 1 percent of those with endometriosis.
It should be noted that although ovarian cancers are more common in women experiencing endometriosis, the overall lifetime risk for developing ovarian cancer is still low.

Although endometriosis has the potential to impact everyday life, it is not cancerous. While some studies have demonstrated an increase in risk of certain types of cancers in those with endometriosis, the increase in risk is not much higher than those who do not experience the condition.
If you’re experiencing symptoms of endometriosis, visit your doctor. They can provide a full diagnosis and develop a treatment plan for pain management.
