Abnormal mammogram and genetics

Question

My recent mammogram at age 41 was neg for right breast but for left it was a "new asymmetric density left central, mammographically and benigh appearing measuring approx 1 cm and most closely resembles focal glandular tissue (BIRADS II)." A surgical consultation was recommended.  My sister had breast cancer when she was 47.  I had a baby 6 months ago, nursed for approx 3 weeks, and 2 months ago started bcp microgestin fe 1/20 which I intend to stop due to several side effects.  This finding frightened me due to my genetic history.  Can a report like this lead to cancer?  We are considering a second child, and I was told that most likely the surgeon will want another mammogram in 6 months but no biopsy - 6 mos is a long time at my age to wait to conceive.  Is a biopsy possible in this case?  My ob/gyn exam in October was negative and the radiologist also reported no palbable mass.  If a biopsy is done, will there will be a need for a 6 mos follwup mammogram?  So, I'm concerned about what this all means and the timing.  Thanks so much.

I am 58 years old and recently had a Mammogram with a finding of the left breat hetergeneously dense which resulted in a recommendation for an utlrasound. This found a ACR BIRADS category 3-probably benign findings. This was a 14mm mass which they believe is a debris filled cyst. They also discovered two 3mm simple cysts. What are the chances of any of these being cancerous and what is the best procedure for follow-up? What causes cysts?

Dear kat100: A BIRAD category 2 generally indicates a benign (non-cancerous) finding. The recommendations (annual mammogram) and statistics (5/10,000 chance of this being breast cancer) are the same as BIRAD 1 (negative examination). This category is for cases that have a finding that is characteristically benign such as cyst or fibroadenoma. Your family history may be the reason that the surgical opinion was recommended. If the surgeon is a breast specialist, he/she may be better able to help you determine what steps need to be taken, considering your desire to have a second child.
