Characteristics of liver cancer
Liver cancer is the third most common malignant tumor with a mortality rate second only to gastric cancer and esophageal cancer.
The early symptoms are not obvious, and the late stage mainly manifests as liver pain, fatigue, weight loss, jaundice, ascites and other symptoms.
1. Liver cancer with highest incidence rate
Lung cancer has the highest incidence rate among malignant tumors. Among the 25 major cancers in the world, the incidence rate of lung cancer ranks first among male cancers and fifth among female cancers.
With environmental pollution, the increase in the number of smokers, and the improvement of human life span, the incidence of lung cancer is increasing year by year, especially in cities. It may become the main cause of death among residents in our country in the next 30 years.
Despite years of research, the survival rate of lung cancer patients is still very low, with a 5-year survival rate of only 13%. This shows that the mortality rate of lung cancer is very high and treatment is very difficult.
2. Lung cancer cells are most likely to metastasize
The lungs are the largest organs in the human body, occupying almost the entire upper body. At the same time, the lungs are the place where all the blood in the human body obtains oxygen. The blood in the whole body must reach the lungs after circulation, thereby obtaining oxygen and bringing it to all parts of the body, so Lung cancer is the most likely to metastasize and is also difficult to control.
3. Liver protection function
Once impurities are inhaled into the lungs, they will be cleared out by coughing, so it is somewhat difficult to directly administer drugs to lung cancer.
4. lung cancer affects the body
As mentioned above, the lungs are the main way for the body to obtain oxygen, so once lung cancer occurs, the function of the lungs will inevitably be reduced, and the impact of abnormal lung ventilation function on the body will be quickly apparent.
