First, what is a liver cyst? Cysts, not tumors at all, but – “bubbles”! Liver cysts are bubbles that grow on the liver. 90% of cysts are hereditary. 90% of the bubbles are hereditary, inside is water, so also called “blisters”; other causes are: trauma, parasites, inflammation. These are not water: they may be blood, worms, bile. Therefore, most liver cysts are congenital blisters. So, if they are congenital, why weren’t they there before? Because, this kind of congenital, not you born out of life, but you are congenital easy to grow cysts. It’s not really possible to say when they start to grow. In general, the liver cysts detected by the physical examination are basically congenital “blisters”, which are not tumors, let alone cancer. If they are congenital “blisters”, even if there are a lot of them, you generally do not feel uncomfortable. Whether there is discomfort or not, mainly depends on the size and cause: 1, congenital hereditary cysts: if it is too big, larger than 10 cm, or pressed to the stomach, gallbladder, diaphragm, you may have a bloated stomach, yellow skin, breathing difficulties; if there is inflammation inside the “water”, you may have a stomachache, fever. 2, trauma-induced cysts: if there are many cysts, even if there are a lot of them, you generally do not feel any discomfort. 2. Cysts caused by trauma: you may have stomach pain and fever. Inflammatory cysts: you may have stomach pain, yellow skin and fever. 4.Cysts caused by parasites: there may be stomach pain, yellow skin, fever, bloated stomach, large liver, and water inside the stomach. In general, most of the small cysts are congenital “blisters”, you will not feel their existence. Third, will it become cancer? Liver cysts are benign, so they basically have nothing to do with cancer. What we need to be concerned about is not whether it will become cancerous, but whether it is a cyst or not. Therefore, we should do the following: 1. Do the examination to make sure whether it is a cyst or not, if the ultrasound is not sure, we can do the enhanced CT or MRI; 2. Regularly review the ultrasound and some tumor indicators (CA199, CEA, AFP, etc.); 3. If you really can’t figure it out, you may need to do the hepatic puncture. A liver cyst that becomes cancerous may not be a cyst at all. Overall, it is almost impossible for liver cysts to become cancerous, so don’t worry about it. Should I take medicine? Generally speaking, liver cysts found by physical examination are basically congenital and will not be uncomfortable. Therefore, there is no need to take medicine, and the liver cysts will not get smaller even if you take it – it’s useless. Only, you have stomach pain, fever. Only then will you consider “taking medicine”. So, since taking medicine is useless, what should we do about these congenital hereditary “blisters”? 1.If there is no discomfort, review the ultrasound once a year; 2.If there is some discomfort and the “blisters” are bigger, we may need to operate or ultrasound puncture; 3.If there are a lot of “blisters”, it is called polycystic liver, which affects the function of liver, and it may be possible to have a liver transplant. Liver transplantation. Therefore, taking medicine is useless! Overall, medication is generally useless, small ultrasound review, large may need surgical treatment. Never, don’t be fooled~~ V. Summarize 1, basically are congenital blisters, purely benign; 2, basically have no discomfort, can’t feel it; 3, basically and cancer has nothing to do with, don’t be afraid; 4, basically don’t need to take drugs or surgery, regular checkups. Let him be, regular checkups are enough!
