Is liver cancer contagious? How to prevent liver cancer scientifically to avoid the disease?

After the hepatitis B virus (HBV) invades the liver, it replicates in large quantities, infects liver cells, causes the body's immune response, forms local inflammation and necrosis, and causes liver damage. On the basis of viral hepatitis, cirrhosis is more likely to occur, and further develops into liver cancer. The so-called transmission, in simple terms, is the transmission of a disease from one person to another through some means. Transmission must meet three conditions: the source of infection, the route of transmission, and the susceptible population. None of the three can be missing. Clinical data proves that cancer patients themselves are not the source of infection.

According to current research results, it can be said with certainty that cancer is not contagious. Medical staff who take care of liver cancer patients have long-term contact with patients, but they have not been found to have a higher incidence of cancer than the general population. These facts show that liver cancer is not contagious. Therefore, to this day, all hospitals do not adopt an isolation system for liver cancer patients.

Liver cancer is not contagious, so we should not look at liver cancer or any other cancer patients with disgust. Liver cancer patients themselves should not have psychological burdens and should cooperate with treatment actively and optimistically.

To prevent liver cancer, you should pay attention to the following points in your daily life

1. Prevent hepatitis

Using hepatitis vaccines to prevent hepatitis and thus liver cancer has become one of the most promising ways to prevent liver cancer. Not only should children be vaccinated with hepatitis B vaccine when they are born, but adults who have not been vaccinated with hepatitis B vaccine and have not had hepatitis can also be vaccinated with hepatitis B vaccine. This can block some hepatitis from developing into liver cancer.

2. Stay away from carcinogens

Do not eat moldy or mushy food, as the aflatoxin contained in such food is a carcinogen. Eating moldy food is very likely to cause liver cancer.

3. Quit drinking

Alcohol in the human body needs to be detoxified by the liver, the largest chemical factory in the human body. The acetaldehyde produced in this metabolic process is extremely toxic to the human body and can cause cell damage, fat deposition in liver cells, inflammation and necrosis of liver cells, and hyperplasia of fibrous connective tissue, which can eventually lead to cirrhosis of the liver, and some cirrhosis of the liver will turn into liver cancer.

4. Regular physical examination

The risk of liver cancer in patients with chronic hepatitis B or C is 10 to 30 times higher than that of normal people. If hepatitis is cured, but the damage to the liver caused by the hepatitis virus has not disappeared, that is, the basis for cancer still exists, so regular examinations should be conducted. For people over 35 years old who are positive for hepatitis B surface antigen, have chronic hepatitis or liver cirrhosis for more than 5 years, and have a family history of liver cancer in three generations of their direct relatives, testing alpha-fetoprotein and liver B-ultrasound every six months is the most effective way to detect liver cancer in the early stage.

5. Actively exercise

The occurrence of liver cancer is also related to the body's immunity. Under normal circumstances, cells in the human body may form cancer cells, but the human immune system has the ability to eliminate these cells, and the human body will not develop cancer. When the human immune system weakens, it is easy to develop cancer. Active exercise and strengthening the body's immunity are also important aspects of preventing liver cancer. Hepatitis B patients should have good living habits, have a regular daily routine, do appropriate physical and mental exercise, and maintain an optimistic mood. This can strengthen the physical fitness, improve the body's immunity, and prevent cirrhosis and liver cancer.

As relatives of liver cancer patients, we must respect them, accompany them through difficult times, help them build confidence in defeating liver cancer, not discriminate against them, and take good care of the patients' daily lives. We must not listen to rumors about the transmission of liver cancer, because daily contact with patients will not transmit liver cancer. So we advise everyone that if family members or friends have cancer, don't worry about transmission, but spend more time with them and give them warmth and love. This will help the patients recover soon.
