Breast Cancer Risk Lower in Women With History of Ovarian Cysts

Benign (not cancerous) ovarian cysts are fairly common. Some women with ovarian cysts also have problems with infertility and irregular menstrual cycles, which suggests that ovarian cysts may be associated with abnormal hormone levels. Because of this, some researchers thought that ovarian cysts might be associated with a higher risk of breast cancer.

A study found that the risk of breast cancer was lower in women with a history of ovarian cysts. The reason for this lower risk isn't clear. More research needs to be done on the relationship between ovarian cysts and breast cancer risk. But the results are good news if you've been diagnosed with benign ovarian cysts.
