Graves’ Disease is a disorder in which the body’s immune system mistakenly attacks normal thyroid cells, leading to excess generation of thyroid hormone and resultant problems such as irregular heartbeat, anxiety, eye and skin diseases, and tremors.
Hyperthyroidism or overactive thyroid occurs when the thyroid gland — an organ crucial to physiological functions such as breathing, controlling metabolism, and maintaining body temperature — overproduces the thyroid hormones.
Thyroid cancer involves malignant tissue growth on the thyroid gland in the neck. There are different types of thyroid cancer, for which surgery is typically the main treatment.
Thyroid nodules are abnormal but typically noncancerous growths of tissue within the thyroid gland.
