5. Goiter and Thyroid Nodules: Harbingers of Trouble
Having a goiter, an abnormal enlargement of the thyroid gland, or thyroid nodules (lumps in the thyroid gland), can increase the risk of thyroid cancer. Both conditions may occur due to an imbalance in the production of thyroid hormones or iodine deficiency.
In most cases, thyroid nodules are benign; however, a small proportion can be cancerous. Similarly, while most goiters are noncancerous, they indicate that the thyroid gland is not functioning correctly, and in some cases, they may contain cancerous nodules.
It’s important to remember that the presence of a goiter or thyroid nodule doesn’t mean cancer is inevitable. However, it warrants further investigation. If you notice swelling or a lump in your neck (where the thyroid gland is located), it’s important to have it checked by a medical professional.
In the next segment, we’ll continue to unravel more causes of thyroid cancer, focusing on existing thyroid conditions, certain medications, obesity, and dietary factors. (5)
