Cervical Node FNA Biopsy Tomorrow

Hi all. Tomorrow I am having a US guided FNA biopsy of my cervical lymph nodes. How I got here..... I am NED from an Inflammatory Breast Cancer stage 3c. My original diagnosis what November 2014. I had 6 rounds of followed by 12 Taxol with Perjeta and then Herceptin for a full year. I had a modified radical mastectomy and then 37 radiation treatments. I recently went to my family Dr for what I thought was an ear/throat infection with very sore neck lymph nodes to touch. Blood work showed no infection and my ears and throat were clear. Just so happens I had a 6 month check with oncologist the next day. Based on no clear reason for very swollen cervical lymph nodes in my neck (on cancer side). She ordered CAT scan. Scan showed they were enlarged, but she couldn't tell why. Now, on to the biopsy. I try not to worry, but we all know how that goes. I have a dry cough that is uncontrollable some times. Especially at night. I worry that I could have enlarged chest nodes as well. I know I just need to get through and try to not expect the worst, but we all know how that goes. Thanks all for listening. Anyone with any thoughts or experience?
