The likelihood of malignancy in a cold thyroid nodule is highest in which age group?

The likelihood of malignancy in a cold thyroid nodule is highest in which age group?

• A. Patients over 60 years.
• B. Patients between 40 and 60 years.
• C. Patients under 40 years.
• D. Children under 10 years.

Answer: (C)

Malignancy risk in a cold thyroid nodule is influenced by age, with younger patients more likely to have a cancer than older individuals. Thyroid cancers, especially papillary carcinoma, tend to present in children and young adults, while nodules in older adults are more often benign goiters or adenomas. Because the relative likelihood of cancer declines with advancing age, the group under 40 has the highest probability of a malignant cold nodule among the given options. In practice, a cold nodule in someone younger than 40 prompts careful evaluation with ultrasound characteristics and consideration of biopsy to rule out cancer.
