To clarify, there's definitely something there per the multiple mammograms and ultrasounds, they just don't know if it's a bad thing or a benign cyst, so they say wait 6 months.
I'm pushing for a 2nd opinion and a biopsy, but wanted feedback because I don't know what is "normal".
If they know something is there, then I can't believe they are not going to do a biopsy!!!!

PUSH for that second opinion!!!!!!!
Ditto to these 2 posts and really, all of the above.
This is coming from someone who has been there and done that many, many times that it's not scary anymore. And that's even with my mom and aunt having breast cancer. I have very dense breasts with hundreds of cysts so self examination is out of the question for me.
Your friend needs to find a surgeon who specializes in breasts not just her gynecologist. And it's true, breast cancer is slow growing so 6 months is probably ok but who wants to wait for those 6 months if there's a question?? She should demand the name of a surgeon and have that spot aspirated. That would put an end to the uncertainty - for her and for her dr's.
If she's uncomfortable asking her gyno then she should ask the radiologist for another dr. who specializes in this area.
