Suspicious Breast MRI

I was dx 4 1/2 years ago with IDC left breast..stage 1..node neg...trip. neg..AC and 33 rads. Have been faithful to all follow up appts with surgeon, onc. mammo's etc. Recently had MRI baseline due to prior history. All clear on mammo's. MRI came back with right breast showing markedly aysymmetric nodular and somewhat confluent enhancement. Was called back for ultrasound and nothing was found. I now need to go and have an MRI clip placement followed by wire localization and excisional biopsy. I've read that breast MRI's quite often show false positive results. What are the chances that my current situation fall into that category?
Thank you in advance.

Dear Mishel, It is possible that what is seen on this test is a benign finding, but until it is further evaluated there is no way of being sure.   Your surgeon would be able to put the findings into better context for you, having seen the films, reports and examined you.
