Large 'something' near chest wall

Wednesday, I had my annual mammogram.  This is the first time in 15 years that I was told that 'something' showed up.

The Breast specialis, I saw immediately after the mammogram, viewed the films.

He said there is something in the left breast near the chest wall about the size of a lemon drop. They were too booked up for me to get an ultreasound that day so I will return this Wednesday for the ultrasound.

The breast Doctor told me that if the radiologist thinks it is a cyst, it is my call whether to have it drained or not.

I have NO IDEA what to do. I sure would like to know what this thing is but do not want to appear, panicky.

There is no cancer in our family but I have been on estrogen for 15 years.

Is an aspiration uncomfortable via a radiolgist since this abnormality is so far inward?
Any advice would be greatly appreciated.

Thank You.

Dear lauren128:  An ultrasound determines whether a lump is fluid filled or solid.  Fluid-filled masses are called cysts and are usually benign.  Aspirations of the fluid are done if the cyst is causing pain or discomfort.  If the lump is not bothersome, there is no medical reason to withdraw the fluid

Thank You for answering me.  Tomorrow is the day and I now feel better with your reply.  Months ago, the left breast hurt for over a month but I did nothing about it and the pain finally left. I pray it is a cyst.  I have too much on my plate right now for it to be more than a cyst.  

Again, my thanks.
