12/6/2017To whom it may concern:
I had my annual mammogram on 12/5/17. In 2012, I had an ultrasound and the cyst on the left breast was .6 millimeters. In 2017, it had doubled in size to .12-.13 millimeters. The inexperienced Doctor said I needed a aspiration of the cyst to determine if it is a clear fluid or a fluid that needs a biopsy. However, I have very dense breast, and I have had no children. In 1999, I had cysts in my right breast and they wanted to do a biopsy then. I told them NO. There is no history of breast cancer and I never smoked. I asked her about the right breast, and they said that was fine. Well, if the right breast was supposed to have a biopsy and 1999, and I never had one and now it is ok, what proof is there that the left breast needs a biopsy when it is already determined that the left breast has a cyst the doubled in size. It could decrease just as well. I was told by one Radiologist that cysts come and go in your body, and you would go crazy trying to analyze every cyst. Why should I have a biopsy if 1.-There is no discharge from the nipple or soreness. 2.-Even y other Doctor could not feel anything. 3.- I have NEVER taken hormonal treatment nor do I take any medicine or herbal medicine. 4.-I never smoked or drink hard liquor. I do not see why I need a biopsy for a cyst that doubled in size. That is not enough medical information to tell me I need a biopsy. Please explain if I do in fact need a biopsy.

12/6/2017Whenever we see significant change in any breast masses, whether it is in size or shape, we want to ensure that there is nothing abnormal going on. Breast imaging studies (mammogram, ultrasound, breast MRI) are valuable tools to assess the architecture of the breast, however, a tissue sample from a biopsy is the only way to accurately determine what that mass is. Just because the right breast cyst was not biopsied and is, as you say, "ok", doesn't mean that what is going on in the left breast is the same. The fact that the mass in the left breast has doubled in size warrants further investigation. Living a healthy lifestyle and not having any history of breast cancer does not guarantee that breast masses of any kind should not be further investigated. You could always ask for a second opinion to see if: 1) another radiologist also believes it is a cyst; 2) if so, ask whether the cyst can be aspirated and have the fluid sent for analysis instead of doing a biopsy.
