A member asked:

Do high prolactin levels lead to breast cancer?

2 doctors weighed in across 2 answers

Prolactin: Elevated prolactin levels have been linked to an increase in breast cancer risk, however most women who are not breastfeeding but are producing milk go to the doctor with this complaint leading to dignostic workup and treatment. The risk will be mitigated by the treatment.

Unclear: There are reports that women with higher prolactin levels were associated with an increased risk of breast cancer. However the cause and effect is not completely understood. Among postmenopausal women, prolactin levels were higher among hormone users and lower among obese women. Meaning higher prolactin levels might be associated with already known risk factors for developing breast cancer.
