Evening primrose oil is a fatty acid (linoleic acid) supplement that's available over-the-counter. A few small studies suggest that evening primrose oil may help minimize menstrual cycle breast pain, sometimes associated with breast cysts. But evidence isn't conclusive, and more research is needed. Although the exact mechanism isn't clear, some experts believe that women deficient in linoleic acid are more sensitive to hormonal fluctuations during the menstrual cycle, resulting in breast pain.
Your cyst or lump needs medical evaluation to be sure it's not cancer, so follow your doctor's recommendations. Let your doctor know if you're taking any vitamins, herbal remedies or other dietary supplements.
