Mentions: In most countries, thyroid cancer accounts for approximately 1–5% of all cancers in females and <2% in males. The age-standardised incidence rates (per 100 000) of thyroid cancer, across most populations, vary from about 2–10 in females and 1–3 in males (Parkin et al, 1997). Since the late 1970s, thyroid cancer has consistently been the second most commonly recorded neoplasm (after breast) among Kuwaiti women. During the period 1994–1998, thyroid cancer accounted for 8.1 and 2.1% of all cancers among Kuwaiti women and men, respectively; and 8.7 and 3.3% of all cancers among non-Kuwaiti (expatriate) women and men, respectively. Similarly high relative frequency and incidence rates of the disease have also been observed in other countries in the Gulf region (Figure 1Figure 1
