Why is liver cancer diagnosed at the advanced stage upon examination? The sooner you know these common knowledge about liver cancer, the better

People who are susceptible to liver cancer: They usually eat well, sleep well, have no jaundice, and no ascites, but when they are checked, they are diagnosed with advanced liver cancer! What's more, my brother has just been diagnosed with liver cancer, and I accompanied him to the treatment and checked, and it turned out that he also has liver cancer! "Things such as weight loss, yellowing face, and loss of appetite should indeed alert you to the possibility of liver cancer, but the absence of the above symptoms does not necessarily mean that everything is fine. In fact, many tumors, including liver cancer, have very vague early symptoms, or even no symptoms. Once they are discovered, they are often in the late stage, and it is difficult to take radical treatment at this time." Experts remind citizens: liver cancer is particularly favored by "family members". If a blood relative is sick, it is best to be vigilant and conduct regular screening. Remind susceptible people that it is best to take a B-ultrasound every six months. Professor Liu Chao of the Department of Hepatobiliary Surgery at Sun Yat-sen Memorial Hospital of Sun Yat-sen University reminds that people with a history of hepatitis B, a family history of liver cancer, drinking, and those who like to eat pickled foods in daily life are all susceptible to liver cancer. It is best for such people to have a B-ultrasound examination every six months to detect the disease in time. "It is especially worth mentioning patients with a family history, because liver cancer seems to favor 'family members', which may be the genetic susceptibility of the disease itself." Liu Chao said that he has recently encountered the same family members who have been diagnosed with cancer one after another, and even encountered two brothers who were on the operating table for liver cancer surgery at the same time. "The occurrence of tumors is caused by external factors through internal factors. The same genes, coupled with similar living habits, make many types of tumors, including liver cancer, like to favor the same family members with blood relations." Case Liver cancer has reached the late stage but no obvious symptoms. Mr. Cai, who is in his seventies, has always felt that his meals are delicious and his body is strong, so he has never participated in the free physical examination organized by his unit for more than ten years since his retirement. Some time ago, Mr. Cai frequently got up at night to urinate, and suspected that he had prostatitis and went to the hospital for treatment. The results of this examination were amazing: Mr. Cai also suffered from hypertension, diabetes, kidney cysts, prostatitis and liver cancer. Even more unfortunately, the liver tumor has invaded the portal vein, and the liver cancer has developed to the late stage. After knowing the test results, Cai Bo and his family were very confused. He had no pain in the liver area, no jaundice, ascites, and a strong appetite. How could he be diagnosed with advanced liver cancer? Why was there no sign before? Analysis of multiple diseases can mask tumor symptoms Professor Wang Jie, deputy director of Sun Yat-sen Memorial Hospital of Sun Yat-sen University, said that many patients in clinical practice have the same misunderstanding as Cai Bo: they think that they cannot have tumors without symptoms such as weight loss, jaundice, ascites and loss of appetite. "In fact, in reality, many tumors lack typical symptoms in the early stage, and even in the late stage, and often lose their therapeutic significance when diagnosed." Wang Jie said that judging whether a tumor has entered the late stage does not depend on whether the patient has symptoms, but on factors such as liver function, tumor size, whether it invades blood vessels, and whether metastasis occurs. Wang Jie said that many liver cancer patients have developed to the late stage, but have no clinical symptoms. There may be many reasons: First, the patient's liver compensation function is good. "For ordinary people, under normal circumstances, as long as there is 30% of the liver, it is enough to maintain the normal functioning of the human body. Although the tumor has invaded the liver and even the blood vessels, as long as 30% of the liver is not affected, there will be no symptoms." Wang Jie said that this does not mean that patients can sit back and relax, because the growth rate of tumors is extremely fast. When tumor cells invade the liver, symptoms such as jaundice and ascites will appear, and by then treatment will be difficult to work. Secondly, if the patient's tumor happens to grow in the center of the liver, and the liver volume has not increased significantly, the tension of the liver capsule is not high, and it does not affect the surrounding nerves, there may be no pain. If the cancer thrombus does not invade the portal vein, or has invaded the portal vein but has not completely blocked it, there will be no ascites. Tumor necrosis can cause cold symptoms In addition, the patient himself has underlying diseases, such as hepatitis, cirrhosis, cholecystitis, gallstones, stomach problems, etc. The symptoms of these diseases are similar to those of cancer, which conceal the truth of the disease. Clinically, many patients have low-grade fever and chills, and they come to see a doctor thinking they have a cold, only to find out they have liver cancer after an ultrasound. In fact, tumor necrosis can also cause low-grade fever, chills, and colds, and the patient's diabetes may mask the weight loss caused by the tumor.
