Multiple Bloody Cyst Aspirations

Hello,
I am 45, I have had several breast cyst aspirations (in both breast) since 2005. Although the aspirated fluid always comes out bloody, the results are always negative for cancer. I go back for my yearly mammogram and US in Dec. I have not had surgery to remove these cysts, even though the cysts continue to appear on US. Since these cysts have been symptomatic in the past, should I consider surgery to remove them?  I don't believe any surgery is 'minor', aspirations included, as they too can have complications, however minor.  I also wonder what contributes to the bloody appearance of the aspirated fluid?  I am concerned that these aspirations will be as annual an event as my mamo.  It is physically and emotionally exhausting.
Thanks for you help.

Dear maShiba:  Cysts are fluid filled structures that are by definition, benign.  When aspirated, the fluid can appear bloody due to hitting a small blood vessel or just the trauma of the procedure.  In general, there is no reason to remove cysts unless they are causing discomfort.  You might have this discussion with a medical breast specialist who can review your situation and make recommendations that would be more specific to your case.  Medical breast specialists are often affiliated with large academic medical centers.
