摘要:I underwent a right thyroidectomy. The biopsy came back as cancer. In this paper, I would like to reflect on my experience as an emergency physician and professor who teaches medical communication and patient safety. I had taken a cervical spine magnetic resonance imaging once, back in my mid-30s, because my right arm had become numb. A simple cyst was incidentally discovered on my right thyroid. The endocrinology doctors assured me there was no cause for concern, so I went on with my life. By the time I turned 40 in early 2017, I decided to get a full medical examination. The cyst that I had forgotten about had changed into a 2.9×3.6 cm-sized oval isoechoic mass with an internal cystic portion. The examination center suggested that I have an ultrasound exam in 1 year.
