Thyroid nodule The prevalence of cancer is higher in males, patients under 20 years old or over 70 years old, and patients with a history of head and neck irradiation or a family history of thyroid cancer. Solitary thyroid nodule Risks for cancer. Solitary thyroid nodules are more common in females yet more worrisome in males. Other associations with neoplastic nodules are family history of thyroid cancer and prior radiation to the head and neck. Most common cause of solitary thyroid nodule is benign colloid nodules and second most common cause is follicular adenoma. Radiation exposure to the head and neck may be for historic indications such as tonsillar and adenoid hypertrophy, enlarged thymus, acne vulgaris, or current indications such as Hodgkin's lymphoma.
