Thyroid cancer is the ninth most common cancer in the U.S. with increasingly more cases each year. Thyroid cancer occurs when thyroid cells (the cells that produce thyroid hormones which help regulate the body’s metabolism and malfunctioning causes hypo or hyperthyroidism) become compromised with cancer.

A history of thyroid cancer can spell trouble for your thyroid health. An abnormal RET oncogene can be passed from parent to child and may increase your risk for thyroid cancer. A family history of goiters as well as precancerous polyps in the colon may also raise your risk.
