Hemorrhagic ovarian cysts are nearly always benign (noncancerous). In addition, the Ovarian Cancer Research Alliance states that most ovarian cysts do not indicate a risk of future ovarian cancer.
However, a 2019 study suggests that complex cysts and solid masses have associations with an increased risk of cancer. The researchers noted that simple cysts did not have the same associations.
A doctor can determine whether a cyst is simple or complex. A person may wish to make an appointment with a doctor if they have concerns.
