my niece is 25 and has 2 beautiful children, but for the past 4 years she keeps getting breast cysts and after numerous hospital/gp visits still doesnt know why they reoccur? any ideas would be very much appreciated,

Hi Anonymous,
Thank you for your question and for finding EmpowHER. You are good to advocate for the health of your niece. Breast cysts are fluid-filled sacs that can coincide with the menstrual cycle. Often times, doctors take a "wait and see" approach to dealing with them, and don't remove them unless they are particularly large or painful. In women who get them, it is not uncommon for them to reoccur. Some doctors believe breast cysts could have something to do with an over-production of estrogen. It is best to work closely with a trusted doctor in these cases to make sure proper treatment and monitoring is carried out.

Good luck, and let us know how you're niece is doing, or if you have more questions.
