Waiting on Breast Biopsy results

Hi Everyone. Im just here in the hope that anyone has had a similar experience and can shed some light. I am 40 and have just been for my 4th mammogram. I have very lumpy cysty breasts so i always go back when i find something new. The doctor doing my breast exam said he wasnt overly concerned, however when i went for my mammogram she said there had been some changes since my last mammogram a year and a half ago. She said there was some scarring and pulling but there was no mass. She said she would need to do a biopsy and when i asked was this concerning she said she couldnt reassure me 100% but they hope its nothing.

To say i am freaking out is an understatement as she also used the word distortion and google did not fill me with much hope at all after looking that up.

Has anyone experienced anything like this?

Thanks all
