Thyroid Problems can range from harmless goiter (enlarged gland in the neck), which require no treatment. The thyroid can be very dangerous and can become a thyroid cancer. The common problem of the thyroid is producing an imbalanced amount of thyroid hormone. Excessive production leads to Hyperthyroidism, and Insufficient secretion of thyroid hormone leads to hypothyroidism. The thyroid problem is managed well with the help of a specialized doctor.
