1. Five manifestations of liver cancer
1. Being thin and lacking in strength
Generally speaking, this symptom often appears in the middle and late stages of liver cancer. The main reason for this symptom is that the size of the tumor is already relatively large, and the various products metabolized by the tumor will directly cause biochemical changes in the human body, making the intake of food for patients with liver cancer less and less, and cachexia will also occur.
2. Persistent fever
Generally speaking, liver cancer can cause low-grade fever, and the body temperature is generally maintained at around 37.5-38 degrees. The normal person's body temperature should be around 36.3 to 37.2 degrees, which is slightly higher than the basal body temperature.
In fact, the symptoms of patients with liver cancer are somewhat different from those caused by common cold and fever. If the fever is caused by a cold, a series of symptoms such as chills and chills will not appear, but patients with liver cancer will.
3. The common symptom of digestive tract
is that the stomach capacity is greatly reduced. Perhaps this patient with liver cancer could have eaten two bowls of rice before, but now he will feel full after eating one bowl of rice, and everything will reach the upper abdomen, and even a series of problems like nausea, vomiting and diarrhea will appear.
4. Severe pain
The site of pain is where the liver cancer occurs, that is, the location of the liver.
For example, there are some places under the right rib or xiphoid process. The general pain process of liver cancer patients in this position is persistent dull pain, and some patients are accompanied by occasional tingling.
In addition, in addition to the possible pain in this part, there are some patients whose pain is in the right shoulder. Why is there pain in the right shoulder?
this kind of pain is more common in patients with liver cancer whose right lobe is close to the diaphragm tumor, because the diaphragm of patients with liver cancer will be squeezed by the tumor, which is very different from scapulohumeral periarthritis.
5. Hypoalbuminemia
The main manifestation of hypoproteinemia is edema. If you have the above four symptoms and edema, you should initially consider whether it is liver cancer.
In China, the diagnosis rate of liver cancer is very low. On the one hand, the screening of liver cancer is not popular enough; on the other hand, people don't fully understand the early symptoms of liver cancer, and they just treat it as a common ailment, which is delayed until the late stage. Therefore, experts say that in order to improve the early diagnosis rate of liver cancer, one is that high-risk groups should have regular screening for liver cancer, and the other is to understand the symptoms of liver cancer. Once found, they should seek medical treatment in time.
2. Methods to prevent liver cancer
1. Prevention —— Drive away the factors that damage the liver
Dr. Wang Dong believes that although the cause of liver cancer is not very clear at present, it has been confirmed that it is related to drinking, environment and hepatitis virus, so the prevention of liver cancer also needs to start from these high-risk factors.
controlling virus infection and progress
the world health organization estimates that there are about 9 million chronic hepatitis b patients in China. Although hepatitis B is not a life-threatening illness, it is the main pathogenic factor of liver cancer.
Once infected with hepatitis virus, the virus replicates and becomes active in the body, which will cause damage to the liver. Long-term damage will lead to cirrhosis and eventually lead to liver cancer.
Therefore, the best way to avoid hepatitis virus is to inject vaccine; If you have been infected with hepatitis B virus, you must follow the doctor's advice for antiviral treatment to reduce the incidence of liver cancer.
alcohol restriction
alcohol is easy to cause fatty liver, which will develop into liver cancer under certain conditions, which is mainly related to the metabolites of alcohol. In addition, studies have shown that alcohol is a clear carcinogen for patients with hepatitis B.
Dr. Wang Dong also stressed that patients with hepatitis must avoid drinking alcohol, because it will promote the development of liver cancer.
improving living habits
drinking polluted water, eating nitrosamine-containing food and moldy food will all induce liver cancer.
The research results of disease research institutions show that aflatoxin is positively correlated with the canceration of liver cells. Long-term consumption will destroy human liver tissue and even induce canceration in severe cases.
2. Screening-Early detection of liver cancer
Wang Dong said, "Early liver cancer has almost no symptoms, and it has missed the best treatment opportunity to seek medical treatment when symptoms appear." Therefore, early detection is an effective way to improve the survival rate of liver cancer.
For patients with liver cirrhosis, long-term heavy drinking, family history of liver cancer, HBV or HCV infection, liver cancer screening should be conducted once every six months, including liver ultrasound and AFP. Once abnormalities are found, further examination should be done in time.
3. treatment-surgery is the first choice for treatment
for early liver cancer, the first choice for radical treatment is surgery.
after the diagnosis of liver cancer, the doctor will analyze the tumor size, location, number and liver function of the patient, and choose the most appropriate treatment method in combination with medical technology and the wishes of the patient.
If the patient can tolerate surgery, surgical resection is the first choice; However, for a single tumor with a deep liver and a small diameter, the therapeutic effect of local ablation is also quite good; For those patients with poor liver function, liver transplantation may be more suitable.
