Thyroid Disorders: More Common than You’d Think

3. The thyroid gland’s tissue can overgrow, resulting in a nodule or small lump in part of the gland. Thyroid nodules are the most common thyroid disorder, occurring in up to 50 percent of people over age 50. Most nodules are harmless growths. The ATA estimates that less than one in10 thyroid nodules is cancerous. While most nodules have no symptoms, are never detected and are harmless, some can be large enough to press against the windpipe and cause difficulty swallowing or a cough. A nodule can also become overactive, suppressing the rest of the gland and causing hyperthyroidism.

If you think you may have a thyroid disorder or are concerned about any of the symptoms listed above, it’s important to talk to your health care provider.
