Hepatocellular carcinoma (HCC) is a common malignant tumor with high incidence and mortality rate. Understanding the basic knowledge of liver cancer is helpful for early detection, effective treatment and reduction of its harm.
Definition of
liver cancer and influence
of environmental factors
Liver cancer is a malignant tumor derived from liver cells, which is mainly divided into primary liver cancer and secondary liver cancer. Primary liver cancer refers to cancer originating in the liver, while secondary liver cancer refers to cancer cells from other parts metastasizing to the liver. Environmental factors play an important role in the development of liver cancer, especially diet and living habits. In terms of diet, high fat, high salt and moldy food are the main factors inducing liver cancer, while long-term alcoholism can lead to cirrhosis, thereby increasing the risk of liver cancer. Habits such as smoking, lack of exercise and staying up late can also adversely affect liver health and increase the risk of liver cancer. Hepatocellular carcinoma (HCC) is pathologically characterized by degeneration, necrosis, and neoplasia. There are various methods to detect liver cancer, among which imaging examinations such as ultrasound, CT and MRI are commonly used research methods, and serum alpha-fetoprotein (AFP) detection also has important reference value. These methods not only help to confirm the existence of liver cancer, but also to understand its development and provide support for subsequent treatment.
2. Early Manifestations and Disease Evolution
of Liver Cancer
Liver cancer shows different characteristics in different stages. Early liver cancer is often insidious, and patients may have only a slight sense of fatigue and loss of appetite, and many people do not even have obvious manifestations. However, as the disease progresses to the middle stage, hepatomegaly, abdominal pain, significant weight loss, and yellowing of the skin and whites of the eyes (jaundice) begin to appear. At this time, liver function continues to deteriorate, affecting the normal life of patients. In the late stage, these phenomena are more serious, abdominal distension and even ascites are obvious, pain is aggravated, and patients may suffer from general fatigue, coma and other life-threatening conditions caused by liver failure. Understanding the manifestations of liver cancer at different stages can help patients and their families to identify the changes of the disease in time, and strengthen the attention and management of the disease.
3. Various treatment methods and therapeutic effects
of liver cancer There are various treatments for
liver cancer, including surgical resection, chemotherapy and radiotherapy. Surgical resection is the main treatment for early liver cancer, especially for patients with small tumors and appropriate location. By resecting the diseased part of the liver, a higher survival rates can be achieved. However, patients with advanced liver cancer usually need a combination of chemotherapy and radiotherapy to control the disease. Chemotherapy uses drugs to prevent the growth and spread of cancer cells, while radiotherapy uses high-energy rays to directly kill cancer cells in the liver. In terms of therapeutic effect, there are various factors, such as the size and number of tumors, the liver function status of patients and the response to treatment. Early detection and treatment of liver cancer is the key to improve the survival rate. In addition to medical means, the daily management of patients is also very important. Good eating habits, moderate exercise and avoidance of alcoholism and smoking are all important measures to combat liver cancer. At the same time, regular review can help to monitor the changes of the disease in time, enhance the therapeutic effect, and improve the quality of life and survival time of patients.
The treatment of liver cancer requires a combination of methods, including surgery, chemotherapy and radiotherapy. Among them, early detection is essential to improve survival rates. Patients can also manage and prevent disease through healthy lifestyle and eating habits. Regular examination can help to monitor the changes of the disease in time and improve the quality of life and survival time. It is very important to recognize and pay attention to the early symptoms and prevention methods of liver cancer and to combat this disease.
