Can intestinal tumors be inherited? Why do many people in the family get sick?

Recently, in Jiaxing, Zhejiang, a 73-year-old man often had black stool. A 4 cm mass was found under colonoscopy and was diagnosed as a precancerous lesion of colorectal cancer. The three brothers and sisters of the old man also found multiple polyps at the same time.

Seeing this information really makes people wonder if intestinal tumors are really hereditary? Why do many people in the family get sick?

In fact, intestinal tumors have certain genetic susceptibility. In other words, people with a family history of intestinal tumors are more likely to suffer from intestinal tumors than ordinary people.

But it doesn't mean it will be passed on to the next generation. As far as current cases are concerned, most patients with colon cancer are sporadic. It is believed that the occurrence of this tumor is related to personal diet, living environment, heredity and other factors, and the family history is relatively high.

In other words, family history is a high risk factor for intestinal tumors. For example, first-degree relatives refer to parents, children and brothers and sisters. If there are patients with intestinal tumors in these people, we should consider the risk of high incidence of intestinal tumors.

Moreover, in recent years, the medical community has found that some tumors have obvious family characteristics. For example, hereditary nonpolyposis colorectal cancer is a family tumor syndrome with autosomal dominant inheritance. Moreover, according to the current research, hereditary nonpolyposis colorectal cancer has obvious family aggregation phenomenon, and its penetrance is usually 80%.

According to relevant statistics, about13 patients with colorectal cancer in China have genetic background, and 5% ~ 6% patients can be diagnosed as hereditary colorectal cancer.

Therefore, even if there is a history of intestinal tumors in the family, it cannot be completely attributed to genetic factors! Mainly related to genetic background and other factors.

So what is the genetic background? In fact, it is a factor related to genes. For example, familial multiple intestinal polyps are genetic problems. However, in the same family, life, eating habits and preferences are similar, which makes other factors such as diet superimposed on family genetic factors, leading to more people suffering from intestinal cancer in the family.

Just like a message I read on the Internet some time ago, four people in a family of seven got colorectal cancer. So if you find that someone in your family has this situation, you must screen in advance! Even at the age of 20, it is recommended to start, because there is a chance of intestinal tumors at this age. The main reasons are eating unhealthy food and irregular lifestyle for a long time, especially those with medical history in the family.

In daily life, you also need to pay attention to the following related matters:

Eat moderately, and eat less food and red meat that contribute to damp heat. In traditional Chinese medicine, these things are easy to get wet and produce phlegm, easy to make a fire, and carcinogenic substances will be produced during metabolism. It is suggested to eat more foods with high fiber and heat-clearing and detoxification, which is helpful to clean up intestinal damp heat, improve intestinal environment and reduce the incidence of cancer.

Eating more crude fiber vegetables and intestinal cancer has a lot to do with diet. You can eat ingredients rich in vitamins and cellulose, such as Chinese cabbage, carrots, eggplant, celery, purslane and so on.

Bad eating habits, such as low-fiber diet, high oil, lack of vitamins and trace elements, may induce intestinal tumors, so don't eat such ingredients.

Active exercise or excessive weight or fat can also increase the risk of intestinal tumors. Proper exercise can reduce body fat, increase intestinal peristalsis and reduce the retention time of feces in the intestine.

Long-term smoking and drinking are risk factors for intestinal tumors. The longer you smoke and the more times you smoke, the greater the chance of getting sick. Therefore, getting rid of bad habits is one of the important ways to reduce the occurrence of intestinal tumors.

In addition, pay more attention to the changes in physical details. If there are abnormal conditions such as bloody stool or diarrhea, don't ignore them. You should see a doctor in time.
