MRI readings by radiologists must contain every suspicious area and anomaly. My first MRI's, post Tx, were not "clean" and caused me much angst until they were interpreted by the head & neck surgeon. It was an entire year until I had a normal MRI.

The biopsy is the gold standard for diagnosis. Scans and x-rays are only a part of the diagnostic workup.

If you're freaking out, a perfectly normal reaction, ask for some anti-anxiety meds. I took them all though treatment.
