Possible Liver Mets

I finished my Breast cancer treatment (chemo, surgery and then rads) a year ago. I moved and my new oncologist wanted me to have a eye to mid-thigh PET scan which showed something on my liver. I had a follow up MRI in December and they found two lesions (each .9 cm). They wanted to wait a couple months and do a repeat MRI which I had this past Saturday. I received a phonecall and my report yesterda and both lesions have grown to 1.4 cm. They ruled out cysts and the report states 'highly suspicious for hepatic metastatic disease'. I'm having my biopsy done next week but already freaking out that I have mets. Has anyone had a similar experience
