It is known that many people lose their lives due to liver cancer in China every year, and liver cancer has become a major killer of people’s health. What are the early symptoms of liver cancer? Liver cancer is a malignant tumor that occurs in the liver and has a high mortality rate. The cancer caused by cells in the liver is called “primary liver cancer”, while the liver malignant tumor formed by cancer metastasized from other organs of the body to the liver is called “secondary liver cancer”, also called “metastatic liver cancer”. It is also called “metastatic liver cancer”. According to the histological classification, primary liver cancer can be divided into “hepatocellular type”, “bile duct cell type” and “mixed type”. The initial symptoms are not obvious, and the late symptoms mainly include liver pain, weakness, emaciation, jaundice, ascites and other symptoms. China is a big country of hepatitis B. Most of the liver cancers in China develop on the basis of hepatitis B cirrhosis, and the number of hepatitis C patients is also increasing gradually, and hepatitis B may also develop into liver cancer afterwards.
The symptoms of early stage liver cancer include
1. Fever
A considerable number of patients will have sweating and fever, most of which are low to moderate fever, while a few patients may have high fever, above 39℃, and generally the symptoms of liver cancer are not accompanied by chills. The fever of liver cancer is mostly cancer fever, which is caused by the release of pyrogen into the blood circulation after the necrosis of tumor tissue.
2.Loss of weight and weakness
Symptoms of hepatocellular carcinoma are often more weak than other tumor patients, which is similar to chronic hepatitis patients. The causes of weakness are unknown, which may be due to digestive disorders, lack of energy due to impaired nutrient absorption, or decreased liver function due to damaged liver cells, which may cause metabolic disorders, inactivation of certain toxins in time, or release of toxic substances due to liver cancer tissue necrosis.
3.Oedema of lower limbs
Patients with hepatocellular carcinoma and ascites often have lower limb edema, which may occur in the ankle in mild cases or spread to the whole lower limb in severe cases. In clinical practice, we have seen some patients with high edema of lower limbs, and the water can ooze out from the skin of thighs.
4.Digestive tract symptoms
Decreased appetite, intensifying after meals. Epigastric fullness. Ambiguous gas, dyspepsia, nausea, weakness and emaciation are the early gastrointestinal symptoms of liver cancer, among which loss of appetite and abdominal distension are the most common. Diarrhea is also a more common early symptom of liver cancer.
5.Other symptoms
Right upper abdominal pain mainly consists of continuous vague or dull pain in the liver area, especially at night and after exertion.
Hypothermia often has unexplained low fever. The clinical manifestations of liver cancer are very atypical, and some patients can visit the hospital with high fever, jaundice and acute abdomen as prominent symptoms, and some even visit the hospital with symptoms caused by metastases.
What are the symptoms of liver cancer?
1.Liver enlargement
For patients with enlarged liver, the external manifestations are pain in the liver, abdominal distension and feeling hard to touch. Then this condition needs to be relieved in time. The liver of liver cancer patients is often progressively enlarged, with hard texture, uneven surface, nodules or even giant lumps of different sizes, clear edges, and often painful to touch and pressure of varying degrees. When liver cancer protrudes to the right subcostal arch or subsurface of the saber, local fullness elevation may occur in the corresponding area; when it is located on the diaphragmatic surface of the liver, it will show limited elevation of the diaphragm; and cancer nodules located on the surface of the liver near the lower edge are most easily palpable.
2.Vascular murmur
For some patients, there may be some symptoms that we can’t see but can be detected by doctors. If the cancer mass compresses the hepatic artery and abdominal aorta, nearly half of the patients with hepatocellular carcinoma will hear wind-like vascular murmur in the corresponding area. However, although this sign has important diagnostic value, it is not significant for the early diagnosis of hepatocellular carcinoma.
3.Jaundice
It is mostly caused by bile duct obstruction caused by cancer tumor or enlarged lymph nodes pressing on bile ducts, and also caused by liver cell damage.
4.Signs of portal hypertension
Since many patients with liver cancer are accompanied by cirrhosis, they often have signs such as portal hypertension and splenomegaly.
What are the prevention methods of liver cancer?
1.Do not eat moldy food
Liver cancer is a kind of intestinal liver disease, so the prevention of liver cancer should pay attention to the choice of food to avoid moldy food and pay attention to the expiration date of food so as not to cause the occurrence of liver cancer due to the influence of moldy food.
2.Actively treat precancerous lesions
To prevent liver cancer, we should also pay attention to actively treat some diseases that may cause cancer, so as to stop the disease early and prevent the possibility of cancer.
3.Do not smoke and drink less alcohol
The emergence of liver cancer is actually related to smoking and drinking, because tobacco contains a lot of toxic substances, when these toxic substances are inhaled into the body, it will cause certain damage to the internal organs, and the stimulation will also aggravate the stimulation of intestinal and liver mucosa, leading to local damage and liver cancer.
4.Maintain an optimistic state of mind
It is very necessary to maintain a good emotional state of mind, because long-term depression and tension can easily lead to stagnation of blood and blood clots, which can lead to cancer.
