Show Answer
Correct Answer – B
Ans: B. Hyperparathyroidism
The serum calcitonin level is strongly increased in this type of cancer. After successful total thyroidectomy, calcitonin is no
longer detectable. Increasing concentrations of calcitonin after therapy indicate relapse or metastasis. Hyperparathyroidism is present in 20-30% of patients with medullar thyroid carcinoma.
