9/28/2017I have a fibroadenoma that has been followed for several years (and is stable) and have had multiple cysts in both breasts for several years (I am 46). In this last ultrasound (following mammogram which the radiologist said was stable - though I have very dense breasts), they found three complex cysts in an area where I have a palpable mass in the right breast.

The original recommendation was six-month follow up, but my gynecologist suggested I go to a breast surgeon. Last year, I had a cyst that showed on the mammogram near that location that was 7 x 8 x 5 mm with a thin internal septation. I had a palpable mass there then, too.

When I went to the breast surgeon she found another complex cyst in the other breast (with ultrasound). She recommended an MRI, for which I have to wait a few weeks. Doing an aspiration and biopsy on the cysts didn't make sense, she said, because I have several.

My question is, am I more likely to have cancer because I have several complex cysts? What could have caused the complex cysts, which weren't there before?

The larger one in the right breast ( 8 x 4 x 6 mm) is not round or oval, but looks more like a trapezoid. Should I request that to be biopsied as soon as possible?

Thank you very much for your advice.

9/28/2017shouldn't be higher risk for cancer due to having complex cysts unless the borders of the cysts are very irregular. they are very small too. wait for them to correlate the mammo/ultrasound and MRI together to determine what needs biopsy and what doesn't.
