Fortunately, cancer is rare in children and teens, and most thyroid cancers can be cured or controlled with treatment. If the nodule is large enough, it may be visible at the front of the neck. A nodule may simply be an overgrowth of normal thyroid tissue, a swelling caused by inflammation such as in autoimmune thyroid diseases or a collection of fluid called a cyst. Reviewed by:
As small as it is, though, the thyroid has an enormously important job to do, especially for teens. Once the diagnosis is made, a teen with Graves disease will usually start taking an anti-thyroid medication, which blocks the thyroid's production of thyroid hormones. In addition, a fine-needle biopsy may be done to help determine whether a nodule is cancerous.
The tissue or fluid is then sent to a lab to be examined. It's brownish red, with left and right halves called lobes that look like a butterfly's wings. Graves disease , an autoimmune disease, is the most common cause of hyperthyroidism. The thyroid responds by working harder to make enough hormones. So if your thyroid isn't operating properly, you can have problems in lots of other parts of your body.
