From what I was told, nodules can grow but if they grow slowly they are less likely to be cancerous; and this seems like it’s growing fairly slowly….lucky you! If it continues to grow, you might want to look into being evaluated for radio frequency ablation to see if the nodule can be shrunk. My nodule grew slowly and then seemed to speed up. It was 5.6 cm when I had surgery and the size was causing issues. I was diagnosed with Hurthle cell carcinoma. I have a small nodule on my right side thyroid and we are observing it. Medication has been very difficult to get regulated on so I tend to think people should explore all possible options before having removal. Good luck!
