I would like some advice on interpreting the findings of my MRI,which came back as BI-RADS 4A (Suspicious finding and biopsy recommended).I am 56,perimenopausal and prior ultrasound core biopsy (Dec.2006) demonstrated on the left breast "moderate epithelial hyperplasia,stromal fibrosis,focal microcalcifications;a focal area of columnar cell change with hyperplasia and focal cytological atypia".THe MRI report states that" the breasts are composed of scattered fibroglandular tissue,which demonstrates minimal normal progressive background parenchymal enhancement.In the posterior third of the LEFT laeral breast towards the 3:00 position,there is an irregular rounded promptly enhancing mass 9x7mm(AP x transverse),demonstrating progressive contrast enhancementkinetics on the delayed phases.In the posterior thirdb of the LEFT upper outer quadrant towards the 2:00 position,there is an area of libnear and clumped nonmasslike enhancement measuring 1.8x0.7cm(APx transverse),demonstrating progressive contrast enhancement kinetics on the delayed phases.Medially adjacent to the pectoralis muscle in the LEFT breast at 3:00 position,there is a rounded progressive enhancing mass measuring 5mm in size.There is a similar sized lesion on priorb mammograms,and this small enhancing mass likely rectum is consistent with a tiny lymph node.There is no abnormal enhancement in the RIGHT breast .There is no axillary or internal mammary adenopathy."
I am wondering if I should do the MRI guided biopsy now or wait until I see the surgeon,to correlate all the findings.
