Is stomach cancer related to genetic factors, and is stomach cancer hereditary?

The incidence of gastric cancer in China is extremely high, especially among male malignant tumors, second only to lung cancer.

The occurrence of gastric cancer is influenced by a variety of factors, including environmental and dietary factors, genetic factors, Helicobacter pylori infection.

Precancerous disease is associated with a number of diseases.

At present, it is believed that the appearance of gastric cancer may be caused by chromosomal aberrations, each cell of the normal human body has 46 chromosomes, and various carcinogenic factors can cause chromosomal aberrations, so that the chromosomes are different from normal cells in number and morphology, and this chromosomal aberrations are sometimes passed on to offspring, so that the next generation has the possibility of cancer. People who have the possibility of developing cancer do not necessarily get cancer, but the chance of getting cancer is greater than that of the general population. For example, there are many smokers in society, but only a small part of them get lung cancer, which is not only related to the length of smoking, but also related to the individual's constitution and other factors of cancer.

That is, the occurrence of cancer is determined by internal and external causes, and the cancer constitution only has some internal causes, and if external carcinogenic factors, such as radiation, smoking, etc., are added, cancer will occur. Through the above introduction, everyone has a certain understanding of whether stomach cancer is hereditary.

Gastric cancer is related to genetic factors, but people with a family history of gastric cancer do not need to be frightened all day long, and usually pay more attention to acquired factors, such as the scientific rules of diet, etc., does not mean that they will definitely get gastric cancer, and unnecessary fear should be avoided. The most important thing for stomach cancer is to do a good job in primary prevention. At the same time, we should regularly do a good job in early detection, early diagnosis and early detection of cancer prevention.

Hello, the incidence of gastric cancer is regionally different, and diet has a very big relationship, excessive salt and pickled products in the general diet, as well as the irregular diet of young people, now the incidence of gastric cancer gradually tends to be younger, which is also the main reason, and some people are caused by genetic factors.

Medical studies have found that most of the patients with gastric cancer are middle-aged and elderly. However, surveys in recent years have shown that the incidence of gastric cancer among young people is on the rise. Due to the atypical clinical symptoms of gastric cancer in young people, especially the lack of understanding of gastric cancer among young people, the early diagnosis rate is not high, resulting in more misdiagnosis and missed diagnosis.

So, is there a relationship between stomach cancer and genetics?

The occurrence of gastric cancer in young people in China is not only related to poor dietary habits, environment and other factors, but also has a certain correlation with heredity.

To analyze and grasp the incidence of gastric cancer in young people, Ren Jun et al. retrieved and analyzed the medical records of 1839 hospitalized patients diagnosed with gastric cancer by the hospital from 1983 to 2003, and conducted follow-up investigations on the patients. It was found that among these patients, 247 were under the age of 45 (17-45 years old), accounting for the total number of patients. Among them, there were 132 males and 115 females, and their average age was years.

Ren Jun et al. conducted further research on these 247 patients according to the genetic criteria formulated by the International Genetic Conference in Seoul in 1998. The criteria include: at least 3 people in the family with the same disease, one of whom is an immediate relative of the other two; Sick for at least two consecutive generations; At least one patient in the family was diagnosed before the age of 45; Meet at least two of the above criteria.

Ren Jun et al. screened 189 cases with complete genetic data from the above patients, including 39 cases with familial genetic disease background; There were 16 cases of hereditary gastric cancer. The two items were added together to a total of 55 cases, accounting for the total number of persons with complete genetic data.

The results showed that among the 1454 patients with complete genetic data in the middle-aged and elderly gastric cancer group, there were 90 cases of gastric cancer in line with the genetic background or hereditary gastric cancer in the middle-aged and elderly group, accounting for the total number of the group, and there was a significant difference between the two groups (p , suggesting that the incidence of gastric cancer in young people is not only closely related to the family genetic background, but also has a higher genetic incidence of gastric cancer than that of middle-aged and elderly people.

Stomach cancer is not a genetic disease, so it is not hereditary. However, there is a certain genetic predisposition to gastric cancer, which means that the probability of gastric cancer in the offspring of a family of patients who have had gastric cancer will be slightly higher, but this probability is also very low, just slightly higher than that of normal people.

Did you know that cancer is hereditary?

Gastric cancer is not a hereditary disease, but if the family cluster is obvious, it means that there are genetic defects related to gastric cancer, you should develop good lifestyle habits, quit smoking and limit alcohol, eat more fresh fruits and vegetables, try to avoid or eat less pickled products and smoked products, and develop a good attitude.

Hello, gastric cancer patients have obvious familial clustering. The survey found that first-degree relatives (i.e., parents and siblings) of gastric cancer patients had an average of 3 times higher risk of developing gastric cancer than the general population. The more famous ones are the Napoleonic family, his grandfather, father and three younger sisters all died of stomach cancer, and the entire family, including himself, a total of 7 people suffered from stomach cancer.

Hello, stomach cancer has a certain impact on dietary habits, living environment, occupation, etc., most of which are acquired, and may have a genetic predisposition. Pay attention to diet and environmental hygiene, if there is stomach pain, you need to see a hospital immediately, and timely after diagnosis** to avoid aggravation.

Hello, there is a genetic predisposition to gastric cancer Gastric cancer has a tendency to cluster in families. Previous studies suggest that environmental factors may be the main reasons for the occurrence and prevalence of gastric cancer, but genetics and immunity play a certain role in the formation of gastric cancer. Learn (Tang Junhua stomach cancer insists on sunshine) prevention.

The heritability of gastric cancer is close to 1 4, and some genetic polymorphisms that affect the metabolism of harmful substances will increase the likelihood of gastric cancer. Gastric cancer is affected by lifestyle habits (smoking, barbecued food, pickled food), external environment (pollution, etc.) and Helicobacter pylori infection.

Gastric cancer is a relatively common disease in life, the harm is particularly great, and it will be life-threatening when it is serious, but the exact ** of gastric cancer is not very clear, but it is known that gastric cancer is related to some benign diseases of the stomach, that is, what we usually call "gastric disease" such as: gastric ulcer, atrophic gastritis, gastric polyps, residual stomach (that is, the benign lesion of the stomach after surgery residual stomach), gastric cancer of residual stomach We call this residual gastric cancer, gastric cancer is also related to some precancerous lesions of the stomach such as: dysplasia (also known as dysplasia), intestinal metaplasia, etc.; Helicobacter pylori (HP) infection is associated with the development of gastric cancer.

Although the cause of gastric cancer is still overcome, a large number of medical research data show that gastric cancer tends to have a tendency to cluster in families. The study found that gastric cancer has a high incidence in some families, and the prevalence in relatives of gastric cancer patients is 4 times higher than in the control group. Tianjin and Fujian have also found that compared with the incidence of gastric cancer in the general population, gastric cancer is obviously more common in relatives of gastric cancer patients than in the general population.

Hefei BOE-Gastroenterology-Hu Wenhua-Chief Physician-Can Gastric Cancer Be Hereditary?

Hello, at present, there is no definite case to prove that stomach cancer is hereditary, so stomach cancer is not hereditary. However, according to surveys, close relatives of cancer patients are three times more likely to develop the same cancer than those of those who do not have cancer among their relatives. If either parent suffers or shares the disease, the chance of the child developing the disease is 1 2.

Familial colon polyposis is also a genetic disease, and although it is not cancer, colon cancer will occur mostly by the age of 50 if the mutated gene for the disease is inherited at birth. Is stomach cancer or cancer hereditary?

Indeed, many people have this question: Can tumors be inherited? It's no wonder that we see all around us that many generations of a person's relatives have been killed by cancer.

So, is cancer hereditary? In fact, as early as 300 years ago, some people believed that tumors have a genetic predisposition, and since the beginning of this century, with the rapid development of science, this understanding has become more and more scientifically based.

Parents have suffered from cancer, children have a tendency to develop cancer, because the parents' constitution is weak resistance to cancer cells, and their children may also suffer from weak resistance to cancer cells, this is not genetic, but the same weak resistance, but as long as the prevention is done, children can avoid cancer.

I have a genetic predisposition and I have been looking up this answer for a long time, my boyfriend has stomach cancer in his father. died early, his grandfather just found out that I was afraid, ah, I checked all kinds of things on the Internet, and suggested that there be a doctor in the group to help you answer.

Gastric cancer is hereditary, but the probability of heredity is very small, so only timely treatment of gastric cancer, and Tang Junhua learning to maintain a relaxed mood will play a better role in helping gastric cancer.

I'm not a doctor, but based on what you've said, I can say with certainty that there is only a predisposition to the constitution, not genetics. And even if it's a predisposition to the constitution, it's not necessarily stomach cancer.

The first is thyroid cancer. It has been clinically found that if there are 3 or more cases in parents, children and siblings, the probability of inheritance is more than 94%. The second is stomach cancer.

5-10% of gastric cancers are hereditary. The third is lung cancer. Epidemiological reports show that if a close relative has lung cancer and smokes himself, the probability of developing lung cancer is 14 times higher than that of ordinary people.

If you are missing this gene, it doesn't mean you're going to get these cancers, but they want you to be vigilant about the different tests for these cancers. Just finding out that you have that doesn't mean you're going to get any of them, it just means that you have a tendency to get those. When they told me about it, they said there was a 35 to 65 percent chance that any of my family members could develop these cancers if they tested positive for this missing gene.

I don't know if this stomach cancer is hereditary, but my mom died of colon cancer and she also had a mismatch repair defect. So it's probably a bit of an exaggeration to say it's genetic, I'm not sure. However, I'm positive about the palb2 genetics.

Just realize that you may have inherited these issues, and it is enough to determine through subsequent testing. No one can ** know that they have carcinogens in their DNA, and it would be crazy to say you have them without testing. You have two parents, and there's always a chance you're genetic—or not.

Maybe your siblings do, and you don't. DNA is fascinating, but it's as personal as you are. Anyone can develop cancer as a result of lifestyle choices or medical reasons, so being careful about what you do to your body will help you make healthy choices for your quality of life.

Good luck and Happy New Year.

Stomach cancer is not hereditary, the lifestyle habits of the family are the same, so the diseases that are easy to get are also the same Stomach cancer is not hereditary Don't listen to the rumors that cancer is hereditary.

Stomach cancer is hereditary, but it is not 100% inherited. Therefore, when a patient is diagnosed with gastric cancer, the lesion can be removed by surgery in the early stage, and then after the operation, he can also choose radiotherapy, chemotherapy or traditional Chinese medicine to regulate the body.

There is a certain hereditary nature, and there are blood relatives and direct relatives. The heritability is up to four times higher. When there is stomach discomfort, bloating, abdominal pain, etc., it is best to seek medical attention in time to avoid delaying the condition.

In the past two days, the US news introduced a large family without a stomach, 11 cousins, all of whom had their stomachs cut in one go, the reason was to prevent possible stomach cancer.

The grandmother of these people died of stomach cancer many years ago, due to a rare genetic factor. After the cousins were tested for genetics, it was revealed that they all carried their grandmother's genes that cause stomach cancer, and the probability of developing stomach cancer in the future was 70, so the surgeons preventively cut all 11 people's stomachs.

The comrades who cut their stomachs excitedly said, "We will all die in the future, but we will certainly not die of stomach cancer." Of course, how can you get stomach cancer without a stomach!

This seemingly inconspicuous news actually has a very important significance, that is, the specific application of heredity. After a large-scale DNA test, the results will tell the person being tested, what kind of bad genes you have, so you may have some disease, you will die a terrible death, now that you know what will happen in the future, prepare in advance, for example, don't these people all cut their stomachs!

But there are still some questions to ask, for example, is such a large-scale DNA test worth it? What are the specific benefits to the general health of the population? Are the test results sure of possible future diseases?

Is there any better way to prevent possible diseases than excision? If you have nothing to do, you will cut your stomach, who will reimburse you?

In 1998, it was discovered that this gene mutation called CDH1 can cause stomach cancer, and many people in a large family in New Zealand have stomach cancer because of this mutation. People with this CDH1 gene mutation are 70% likely to develop stomach cancer.

During the operation, the surgeon cut out the stomach as if it were a real stomach cancer patient, and swept the lymph nodes around the stomach. Then just connect the intestines and esophagus in one breath, and these 11 cousins who have no stomach all say that "it feels good to have no stomach"!

The stomach is fine, but what about other diseases? If you have a brain tumor, you can't cut your brain in advance! I have to think of something else.
