全国各地已普遍进行了甲状腺肿的普查和防治工作，单纯性甲状腺肿的发病率已大大降低。在流行地区，甲状腺肿的集体预防极为重要，一般补充加碘盐。#专注甲状腺[超话]##玮毫甲状腺团队[超话]##玮毫甲状腺团队##甲状腺##甲状腺癌##甲状腺肿# The general survey and prevention of goiter have been carried out throughout the country, and the incidence of simple goiter has been greatly reduced. In endemic areas, collective prevention of goiter is extremely important, and iodized salt is generally added.

#专注甲状腺[超话]# 检查发现甲状腺肿大或结节比较容易，但临床上更需要判断甲状腺肿及结节的性质，这就需要仔细收集病史，认真检查，对于居住于高原山区缺碘地带的甲状腺肿病人或家属中有类似病情者常能及时作出地方性甲状腺肿的诊断。It is easier to find goiter or nodules on examination, but it is more necessary to judge the nature of goiter and nodules in clinical practice. This requires careful collection of medical history and careful examination. For goiter patients or their family members living in iodine-deficient areas in plateaus and mountains with similar conditions can often make a timely diagnosis of endemic goiter.
