Most of the liver cysts are congenital. If a cyst is found on the liver, look at the size of the liver cyst, if the cyst is relatively small, do not care, do not care. If it is larger, see if the cyst is more than 5cm. If it is more than 5cm, you can consider doing puncture treatment, if it is not more than 5cm, you can observe it regularly to see if it is growing too fast and too big. If it does not affect the liver function, it can be left alone if it is a small cyst, and it can be rechecked every three months to six months or even once a year. If it affects liver function or is too large, we should consider liver preservation and enzyme reduction, and then carry out treatment of liver cyst puncture. Therefore, there is no need to worry or fear about simple small cysts, which will not cause too much impact.
