Thyroid Cancer Types, Stages and Treatment Overview. They are located within the thyroid gland, which is a butterfly-shaped gland located at the lower front of the neck. “These data demonstrate that clinically relevant (1 cm) cancerous thyroid nodules grow more often, and grow faster, than clinically relevant (1 cm) … I am not feeling particularly sick, but with such a large nodule (almost 2 inches), I realize it could be cancer or something else and I am coming to terms with that.

However, the relationship of size to malignancy varies by FNA status. Luckily, most of them are benign. In fact, thyroid nodules are cancerous in fewer than 10 percent of cases. Researchers think that much of this rise is due to the increased use of imaging procedures in the head and neck area to diagnose other conditions. The risk of cancer increased to 15% of nodules greater than 2 cm. An estimated two-thirds of adults have nodules in the thyroid gland, with most either benign or resulting in a slow-growing cancer that is not life-threatening. The ultrasound … The incidence of thyroid carcinoma was significantly higher in nodules > or =4 cm (24%) compared with nodules <4 cm (12%).
