He usually eats well, sleeps well, has no jaundice, no ascites, but once he was examined, he was found to have advanced liver cancer! There is even a case where the brother of the family was just diagnosed with liver cancer, so he accompanied himself to the treatment and had a checkup, but it turned out to be liver cancer too! It is true that you should be alert to the possibility of liver cancer if you lose weight, turn yellow and have no appetite, but the absence of the above symptoms does not necessarily mean that you are fine. In fact, many tumors, including liver cancer, have vague or even no symptoms in the early stage, so once they are detected, they are already in the late stage, and it is difficult to take radical treatment. Liver cancer especially favors “family members”. If your blood relative is sick, it is better to be vigilant and have regular screening. Those who have a history of hepatitis B, family history of liver cancer, drink alcohol and eat pickled food in daily life are all susceptible to liver cancer, so it is better for them to have ultrasound examination once every six months in order to detect the disease in time. Especially worth mentioning are patients with family history, because liver cancer seems to favor ‘self-family’ especially, which may be the genetic susceptibility of the disease itself at work. He has recently encountered repeatedly the same family with cancer before and after, and has even encountered two brothers on the operating table at the same time for liver cancer surgery. The occurrence of tumors is the result of external factors acting through internal factors. The same genes, together with similar living habits, make many tumors, including liver cancer, favor the same family with blood relations. The case: liver cancer has reached an advanced stage without any obvious manifestation Uncle Cai, who is in his seventies, has always felt good about his meals and body, so he has never participated in the free medical checkups organized by his unit for more than ten years after retirement. The first time I saw this, I suspected that I was suffering from prostatitis and went to the hospital. The result is amazing: Cai Bo is suffering from high blood pressure, diabetes, kidney cysts, prostatitis and liver cancer. More unfortunately, the liver tumor had invaded the portal vein and the liver cancer had developed to an advanced stage. After knowing the test results, Cai Bo and his family were very confused. He had no liver pain, no jaundice, no ascites, and his appetite was strong, so how could he have advanced liver cancer upon examination? Why did he not show any signs before? Analysis: Various diseases can mask tumor symptoms Clinically, many patients have the same misunderstanding as Cai Bo: they think that if they do not have symptoms such as wasting, jaundice, ascites and loss of appetite, they cannot have tumor. In fact, in reality, many tumors lack typical symptoms in early stage, and even in late stage, they have no symptoms, and when diagnosed, they often lose their therapeutic significance. To judge whether a tumor is in advanced stage or not, it does not depend on whether the patient has symptoms or not, but on factors such as liver function, tumor size, whether it invades blood vessels and whether metastasis occurs. There may be multiple reasons why many liver cancer patients have developed to advanced stage without any clinical symptoms: First, the patient’s liver has good compensatory function. “For an average person, a liver with 30% of the body is usually sufficient to maintain the normal functioning of the body. Although the tumor has invaded the liver and even the blood vessels, as long as 30 percent of the liver is unaffected, it will not show symptoms. This does not mean that the patient can rest easy, because the tumor grows very fast. When the tumor cells have invaded all the liver, jaundice and ascites will appear, and by then the treatment will not be effective. Secondly, if the patient’s tumor happens to grow in the middle of the liver, and the liver volume does not increase significantly, the peritoneal tension is not high, and the surrounding nerves are not affected, the patient may not experience pain. And if the cancer clot has not invaded the portal vein, or has invaded the portal vein but not completely blocked, then ascites will not appear. Tumor necrosis can trigger cold symptoms In addition, patients themselves have underlying diseases, such as hepatitis, cirrhosis, cholecystitis, gallbladder stones, gastric disease, etc. The symptoms of these diseases are similar to those of cancer, which hide the truth of the disease. In clinical practice, there are many patients who have low fever and chills, thinking they are suffering from cold to come to the doctor, only to find out they have liver cancer after taking ultrasound. In fact, tumor necrosis can also cause symptoms such as low fever, chills and cold; and the patient himself has diabetes, which may also mask the wasting caused by the tumor.
