Friends, maybe one day you got the result of your medical checkup in the hospital, and it shows that you have cysts on top of your liver! You’ll rush to the hospital and ask, “Doctor, what’s wrong with this cyst? Is it cancer? Is it precancerous? Will it turn into cancer? Do I need treatment? In fact, the inside of a liver cyst is a pool of clear water! It is most likely formed by the bile duct cells left in your liver during embryonic life, which slowly secreted fluid after birth! If the cyst is not large enough to exceed 5 centimeters in diameter, or if it is not causing pressure and other problems, you can leave it alone! It’s not cancer! It’s not precancerous! And it won’t turn into cancer! The question is, is the lesion cancerous or not? This is something that needs to be carefully differentiated! First of all, the doctor will choose from the medical history, a good liver does not give birth to cancer, cancer does not give birth to a good liver! The choice of liver cancer will be a plus if the patient has cirrhosis caused by diseases such as hepatitis B, hepatitis C, alcoholic liver, self-immune liver and drug liver! Liver cancer is a plus if there is pain in the liver area, wasting, and more GI symptoms! A doctor’s physical exam that reveals a faceted liver disease, reveals spider moles, reveals ascites, reveals an enlarged liver with nodules on the surface that are particularly hard, liver cancer is a plus! If the blood test AFP is elevated, liver cancer will be a plus! The more important differentiation is still imaging, because the inside of a cyst is water, a fluid, so it has the same, uniform density as water! Whereas inside a liver cancer is diseased meat! It’s denser than a cyst, and cancer must need to have a rich blood supply! So when there is ultrasound, CT, MRI, liver cysts can be found in the liver round, internal density uniform, lower than the density of the meat, and water density consistent with the occupying lesion, the boundaries are very clear, because the center of the cysts is water, there is no blood vessels, so ultrasound can not be found within the cysts of the blood flow signals, CT and magnetic resonance enhancement of cysts will not enhance the contrast agent into the cysts! Theoretically, this is the case, but in practice, individual cases may also have difficulty in differentiating, as to whether it is liver cancer or liver cysts, it is better to leave such differentiation to the specialized gastroenterologists and medical imaging doctors to do it for you! Once the diagnosis is clear, you will know that liver cysts less than 5 centimeters in diameter and without pressure symptoms do not require treatment! If the liver cyst is more than 5 cm in diameter or produces compression symptoms, you guys can go to Gastroenterology and just get treated by ultrasound-guided puncture! But I would like to remind you to be vigilant, there is a kind of multiple liver cysts, such patients sometimes also have cysts in the kidneys, spleen, pancreas, this is a kind of hereditary polycystic disease, the development of the seriousness of the liver and kidney can cause failure, treatment is also very troublesome, sometimes even need to do liver and kidney transplantation, this multi-cystic disease and the ordinary liver cysts that I am talking about today are not exactly the same thing!
