Unfortunately but it must be told that most liver cancers really do not have particularly typical symptoms in the early stage, and they are easy to ignore in life. Another important and controllable reason is that patients themselves do not pay enough attention to it. They seldom have medical checkups, and even if they are ordered by doctors to have regular checkups, they will not do so because of the hassle, inconvenience of medical treatment (such as foreign patients going to big cities) and financial constraints. Liver cancer is really cunning and hides itself well in the early stage, but there are not no traces at all. 1. Feeling tired, bitter in mouth, aversion to greasy food, not wanting to eat and having vertical lines on nails, is it a bad liver? For people who do not have various liver diseases, these are not precursors of liver cancer. Most of these physical discomforts are related to long working hours, high stress, irregular work and rest and diet, and it is impossible to simply determine what the disease is. For people with underlying liver diseases, such as those with hepatitis B, hepatitis C, autoimmune liver disease, alcoholic liver disease, etc., whether you have these conditions or not, you should be alert. 2. Liver disease itself is a very clear early indication The etiology of liver cancer is not completely clear now, and studies have shown that liver cancer is related to hepatitis B, hepatitis C, alcoholic hepatitis and other hepatitis.
