Liver tumors mostly arrive silently. Once the tumor is detected by ultrasound, further CT or MRI should be done to determine the nature of the tumor. Depending on the nature, the next treatment plan will be decided. In this process, if the cyst or hemangioma grows too large, more than 8 cm in diameter, surgical treatment is required. In addition, hepatic adenoma and focal nodular hyperplasia (FNH) are also benign benign tumors of the liver. Liver cysts and hepatic hemangiomas, two benign tumors determined by congenital factors, are born like a seed buried in the liver, except that they germinate at different times, some in their twenties and some in their seventies and eighties. They do not affect the body and usually do not need to be actively treated. The only bad thing is that they will grow slowly. A liver hemangioma that is too big is like a big blood bag, and the action of trauma may cause rupture and even life threatening. Therefore, a medical checkup is needed once a year. For tumor, you can observe it first and review it after 3 months to see if there is any transformation. If the MRI and CT are clear that the hypoechoic area is just a simple fatty liver manifestation, this situation does not need special treatment. You should pay attention to your lifestyle, eat less fatty diet, lose weight, and treat your liver, and then have an annual checkup. If the MRI and CT tend to be malignant, surgical treatment should be considered. Tumors smaller than 3 cm can be cured by radiofrequency ablation treatment.
