From what I read, you most likely have breast cancer
. Birads 5 is most likely to be cancer
. Biopsy now is indicated. If the mass is solid, and spiculated (as mine was - looked like a starburst on the mammo) this is highly indicative of bc.Only a biopsy will give conclusive proof.
However, not all is lost - I had a 2 cm invasive ductal tumour in 2004, had 2 surgeries (Lumpectomy and total axillary lymph node removal). FEC chemo and 25 rads.and still here, loving life.
