Hello, I am a 61 year old woman who goes annually for a routine mammogram. This time they discovered cysts in the right breast. The ultrasound lady said they were fluid filled sacs, and were round and smooth, and are benign. But the radiologist said that even though she is 94-97% certain there is nothing to worry about, she is going to do a needle biopsy tomorrow, just because, as she said They are clustered together so close and I can t see them all that clearly. I have been terrified for days and have been reading online that cysts, even clustered, usually require no further treatment. Does this mean she suspects something?
