儿童肝癌在美国可以看见。在肝炎多的地区更多

作者说“ 但你什么时候听说过小孩得肺癌，肝癌的？” 其实， 儿童肝癌在美国可以看见。有几个亚型。有一种和成人发病机制相似。 儿童肝癌在肝炎多的地区更多。 台湾用了肝炎疫苗后，儿童肝癌有明显降低。
文中诸如此类的例子不止一处。 美国主流媒体科学和医学记者完全分开。 医学科普也都由医生写或经过医生批准后发表。看Webmd和MayoClinic的医学科普文章就很清楚。 作者做制药的科普应该更棒，让肿瘤医师做肿瘤科普。

General Information About Childhood Liver Cancer
Key Points for This Section

。。。。。。

Liver cancer is rare in children and adolescents (teenagers). There are two main types of childhood liver cancer:

Hepatoblastoma: A type of liver cancer that usually does not spread outside the liver. This type usually affects children younger than 3 years of age.

Hepatocellular carcinoma: A type of liver cancer that often spreads to other places in the body. This type usually affects older children and teenagers.

The treatment of two less common types of childhood liver cancer is also discussed in this summary:

Undifferentiated embryonal sarcoma of the liver (UESL) is the third most common liver cancer in children and adolescents. The tumor often spreads all through the liver and/or to the lungs. It usually occurs in children between 5 and 10 years of age.

Infantile choriocarcinoma of the liver is a very rare tumor that starts in the placenta and spreads to the fetus. The tumor is usually found during the first few months of life. Also, the mother of the child may be diagnosed with choriocarcinoma, which is a type of gestational trophoblastic disease and requires treatment. See the Gestational Trophoblastic Disease Treatment summary for information on the treatment of choriocarcinoma in women.

Epithelioid hemangioendothelioma is a rare cancer of the blood vessels that occurs in the liver and other organs. See the Epithelioid hemangioendothelioma section in the PDQ summary on Childhood Soft Tissue Sarcoma Treatment for more information.
