The American Cancer Society says thyroid cancer can be detected early through a variety of medical exams, including annual physicals, medical history analyses, image and blood tests, ultrasound and radioiodine scans.

Radioiodine is a common treatment for thyroid conditions.

No, it was the kind doctor who came bearing the radioiodine capsule in the glass tube.

After treatment, 57 percent of the patients had at least one ultrasound, 24 percent had a radioiodine scan and 15 percent had a PET scan to monitor for signs of the return of their cancer.

Although the radioiodine kills the thyroid cancer cells, it increases the risk of a secondary cancer because it exposes the kidney, bladder and pelvic organs to radiation, Smallridge says.
