What are the symptoms of liver cancer? What should we pay attention to in preventing liver cancer?

For liver cancer, the early symptoms are not uniform, but fever is a typical symptom. Most patients have low fever, and a small number of patients may have high fever. So what are the early symptoms of liver cancer? How can we prevent such a malignant disease as liver cancer? Let's take a look at the following introduction.

What are the symptoms of liver cancer?

1. Fever

A large number of liver cancer patients will have a low fever without chills, and a small number of patients will have a high fever, which can reach above 39°C. Most liver cancer fevers are cancerous fevers, which are caused by the release of pyrogens into the blood circulation after tumor tissue necrosis.

2. Weight loss and fatigue

The cause of fatigue is not clear yet. It may be due to digestive dysfunction, impaired nutrient absorption leading to energy deficiency, or liver cell damage leading to decreased liver function, resulting in metabolic disorders and failure to inactivate certain toxins in time, or the release of toxic substances due to necrosis of liver cancer tissue.

3. Lower limb edema

Most patients with liver cancer will experience lower limb edema. Mild cases mainly affect the ankles, while severe cases may affect the entire lower limbs. Some patients also have severe lower limb edema, with fluid seeping out of the thigh skin.

4. Digestive tract symptoms

Loss of appetite, worse after meals. Upper abdominal distension. Warm breath, indigestion, nausea, fatigue, weight loss, etc. are the early digestive tract symptoms of liver cancer, among which loss of appetite and abdominal distension are the most common. Diarrhea is also a common early symptom of liver cancer.

5. Other symptoms

The pain in the right upper abdomen is mainly characterized by persistent dull pain in the liver area, especially at night and after fatigue.

What issues should we pay attention to in preventing liver cancer?

Chronic liver disease may turn into liver cancer. Chronic liver disease can be caused by various causes, including viral, genetic metabolic, infectious (bacterial, vascular, parasitic, fungal, etc.), drug, autoimmune, fatty (alcoholic and non-alcoholic) and other factors. It can be divided into acute and chronic in terms of the course of the disease. It is generally believed that chronic liver disease (mainly chronic hepatitis B or C) that does not heal for a long time and slowly develops into cirrhosis can cause serious complications in some patients, or eventually progress to primary liver cancer.

China is a country with a high incidence of liver cancer. About 89% of liver cancer patients in my country are related to chronic hepatitis B, and a small number are related to hepatitis C. Therefore, these people are at high risk of liver cancer. The most direct and effective way to prevent liver cancer is to get vaccinated, thereby inhibiting the replication of hepatitis B and (or) hepatitis C viruses, slowing down the progression of liver cirrhosis, improving autoimmunity, and reducing damage from other physical and chemical factors.

A research investigation has shown that if all the people are vaccinated against hepatitis B, the hepatitis B virus surface antigen carrier rate can be effectively reduced from 15% to 1.5% in the next few years.

In addition, to prevent liver cancer, you must quit smoking, control your alcohol consumption, and avoid eating moldy food because moldy food contains the carcinogen - aflatoxin.
