hello, some 2 years ago a thyroid nodule was found incidentally by sono when I saw endocrinologist for hair loss , the nodule did not grow, last August was 10x8x12mm, now in February 12x10x18. I had quite a bit of stress last months. I am 62, height 175cm, weight 66kg. The doctor wants me to have biopsy done, I am not sure, what are the risks? I am on homeopathy - now taking Conium 200C. Thank you
