It depends. There are many factors which affect a given nodule's risk of being a thyroid cancer. These include size, and other features visible on us (ultrasound) and patient age. Because women have many more being benign thyroid nodules than men, the risk for any one nodule is higher in a man. For a typical 1-2 centimeter (1/2-3/4 inch), that risk might be about 4% in a woman, or about 8% in a man.
Higher than female. Benign thryoid nodules in women are very common with a low risk of carcinoma. In the male population... There is a higher chance that a nodule is carcinoma. This should followed up aggresively. http://www.medscape.com/viewarticle/550524.
