still testing

help, i am newly diagnosed triple neg, stage2a, grade 3, neg.node. have had negative bone scan and bi-lateral mastecomy with latissimus flap reconstruction three weeks ago. Have not started chemo yet, but in course of getting into a trial, i needed two more scans. one of chest and one of abdomen. ct scan showed two areas of concern, one in lungs and one in liver. have had pet/ct scan and onc not concerned about lungs, but now wants a liver biopsy. says the image is not consistent with what he would expect for breast cancer met. it is a single solid mass or nodule and he is not sure what it is. I am very scared and wanting to start treatment
