匹兹堡大学医学中心讲的很清楚FNH是良性的.不过以后就诊一定要找肝专科医生看如果尺寸变大

还是要肝外科手术.找个肝内专科医生以后一直跟着他/她看,美国各专科培训区别很大,培训时长也不同.

匹兹堡大学排名虽后,但它的医学院排名挺好的.它家网站上的解释是可信的.

FNH is a benign tumor, or lesion, that forms in the liver. These tumors are not cancer.

FNH is more common in women, mostly between the ages of 20 and 50.

It's the 2nd most common type of benign liver tumor (liver hemangiomas are the most common).

FNH affects between 0.6% and 3% of the general U.S. population. About 8% of all benign liver tumors that aren't hemangiomas are FNH.

Focal Nodular Hyperplasia (FNH) Treatment

FNH tumors do not become cancer. In most cases, doctors only treat FNH that causes symptoms.

Your liver doctor will want to see you every three to six months for follow-ups and imaging tests.

These appointments and scans are to make sure the tumor isn't growing.

Lifestyle changes to treat FNH

Doctors might suggest you stop taking birth control pills if you have FNH. If you keep taking them, your doctor might want you to have routine imaging tests to keep an eye on the tumor.

To support your liver's health, doctors might also urge that you:

• Eat a healthy diet.
• Maintain a healthy weight.
• Exercise.
• Avoid alcohol.

Trans-arterial embolization (TACE) to treat FNH

If your tumor gets larger than the typical 4 to 8 centimeters , doctors may use TACE to shrink it.

During TACE, specialists will inject medicine into the hepatic artery to block blood flow and prevent the mass from growing.

Surgery to treat focal nodular hyperplasia

If the FNH is large, surgeons may remove the tumor.

In partial hepatectomy surgery, or resection, surgeons extract the tumor and a small part of the tissue around it.
