The nurse is screening a group of patients for risk factors related to thyroid cancer. Which patient should the nurse recognize as having the highest risk for developing thyroid cancer?
1. a 75-year-old patient with a history of sinus infections in childhood
2. a 70-year-old patient who refinishes furniture as a hobby
3. an 80-year-old patient whose diet consists largely of red meat
4. an 85-year-old patient who works outdoors without sunscreen
Correct Answer: 1
The most consistent risk factor for thyroid cancer is exposure to ionizing radiation to the head and neck during childhood. For example, many adults in their 60s, 70s, and 80s received x-ray treatments for colds, tonsillitis, acne, and sinus infections during childhood. Exposure to products used in refinishing furniture, a diet of red meat, and failing to use sunscreen when working outdoors are not risk factors for thyroid cancer.
