Genetic liver cancer you
My sister to find the target, relative to the one introduced, but the other side are the father and uncle died of liver cancer was, I saw relatives to introduce the subject, very solid, but I do not know whether there would be a genetic disease, we Sister, said that should it? The boys were very good, because he is the father and uncle, things have not been found, he did not know how big the possibility of liver cancer /
I hope I can help doctors, which has a bearing on the well-being of my sister!
Thanks
Add the question: What can you specifically?
The father and uncle have liver cancer, he should be able to prevent it?
His big chance you get sick
Answer:
Cancer causes 90% of external causes, the genetic causes of cancer in a very small share of the weight. In addition to the multiple polyps of the colon evolved, xeroderma pigmentosum evolved into the external skin cancer, other cancers and more are considered to be no clear relationship between genetic factors. For those few people at the same time or before or liver troubles of the family, perhaps a common living conditions, such as contact with a co-carcinogen factors far more important than genetic factors. In other words, though not genetic liver cancer, but some families tend to gather. Once in a occurrence of liver cancer patients have family members should be vigilant against the disease.
Why liver cancer have a certain tendency to gather the family at present then the majority of scholars believe that:
1, vertical transmission of hepatitis B virus: hepatitis B virus infection and subjected to a long-term virus carriers mother in childbirth or after childbirth may be transmitting the virus to newborns. As the neonatal immune function is not fully developed, can not effectively clear the virus and the formation of persistent infection, resulting in chronic hepatitis, cirrhosis, liver cancer for the last evolution.
2, the level of the spread of hepatitis B virus: hepatitis patients is extremely close contact with family members if there is an infection of hepatitis B virus, it is easy unknowingly affected other people.
3, between the family eating habits, lifestyles and so on are basically the same, we contact the cancer-causing factor is basically the same opportunities.
People in a cancer there is another explanation. The basic view is that no cancer cells were the two gene mutations. The distribution of non-cancer family, these two changes have taken place after birth. The family has a tendency of cancer patients, pregnant mothers, has been cancer-causing factors in this attack. They were born when the body susceptible to cancer cells has been a change, as long as after birth and then suffered a blow to cancer-causing factors, there is potential for cancer, the cancer than the general number of the National People’s Congress. This is the famous “two-hit theory.”
No matter what kind of explanation of the above, this shows that liver cancer is caused by external factors. Therefore, liver cancer patients have family members did not need to consider too many hereditary liver cancer, not to affect their children’s marital problems.
5:00 preventive measures
According to China’s large number of epidemiological investigation in the 1970s put forward “to water, mold, anti-hepatitis” or “water, food control, anti-hepatitis” on the seventh principle is not only initial success, and has The prevention of liver cancer in China has become a feature. Over the past two decades, a number of areas of high incidence of liver cancer, to take a precautionary measure, liver cancer incidence and mortality have declined significantly. Secondary prevention can be summarized as “early detection, early diagnosis and treatment.” Tertiary prevention is a positive clinical treatment.
They believe the prevention of liver cancer should proceed with the following:
The first is to prevent hepatitis, the use of vaccine to prevent hepatitis C in order to prevent liver cancer liver cancer prevention has become a very promising way to one of the only child born to hepatitis B vaccine injection, the adults have not been injected hepatitis B vaccine, was not Can also have hepatitis B vaccine injection. However, the estimated time to take several decades to see results. In addition to the injection of hepatitis B vaccine, the need to pay attention to other routes of transmission control, such as diet, surgery, blood transfusions, injections, acupuncture and hair and so on.
One of the reasons why the incidence of liver cancer is caused by a virus, but also to the prevention of hepatitis B virus from a health diet, living habits begin. To wash their hands, Fencan. It is worth noting that there are those who could not cook hepatitis.
Second, we can not eat moldy, a paste of food, this type of food containing aflatoxin, the cancer-causing substances. Eat moldy food can easily lead to liver cancer. Wash rice and there are free, Professor Wang Jianzhang said, “I think that is not necessarily good in the plastic bag if they are high-temperature, high temperature, food, water more than 16%, it will mold. Moldy food must be dry Dry, for example: corn, peanuts, peanut oil, peanut butter, and so it is easy to moldy food, the food should pay attention to custody. ”
The third is not contaminated water sanitation, drinking water chemicals easy to long cancer. Not necessarily clean water, more than 5 layers of a high-rise roof water tanks, water tanks should be clean in person, the best secondary disinfection of the water tank box should not use contaminated water Chemical substances.
Fourth, Se appropriate. For people to adopt a low selenium-enriched yeast, selenium polysaccharide, the selenium-enriched salt to add elements to increase blood levels of selenium.
Fifth, to reduce the intake of nitrosamines as well as quit smoking, quit drinking. Smoking, Drinking is not good for fatty liver, drink wine, beer, a small amount of alcohol can Relieving Blood promoting blood circulation, but it is not, the effect of alcohol on the human body harmful. Stomach mucosa of the human body have a protective effect of alcohol can digest the gastric mucosa, the cells were injured in the stomach, the food of toxic substances on the stomach easily be absorbed. This will easily lead to alcoholic hepatitis, liver to reduce the body’s immune function and immune function, damage to the liver detoxification function. That is why people who drink alcohol detoxification function of poor, vulnerable alcoholic cause of cirrhosis, liver cirrhosis will be transformed into part of the liver.
