Is cancer related to genetics? If there is no genetic history of cancer in my family, is there a sma

About cancer. This word is no longer unfamiliar to everyone, cancer is a terrible disease in everyone's eyes, once cancer has developed to the middle and advanced stages, it is very difficult, and even the opportunity has been lost. At present, the incidence of cancer is increasing year by year, and in addition to other factors, cancer is also related to heredity.

A small number of cancers have a familial genetic predisposition, such as esophageal cancer.

Colorectal cancer, breast cancer.

Stomach cancer, etc., these cancers are genetically predisposed, if there is a genetic history of cancer in the family, the probability of cancer in the next generation is higher than that of ordinary people, if there is a family history of cancer, it is best to go to a regular hospital for cancer screening on a regular basis, and it should be detected early**.

1. Cancer is indeed partly influenced by genetics, especially in the immediate family.

If two or more people have certain cancers, or if one of the immediate family members has certain types of cancer at a relatively young age, the risk of developing this type of cancer increases in the next generation, and if there is no history of cancer in the immediate family, the risk of developing cancer is smaller.

2. Although some cancers are affected by genes, the influence of genes is not absolute, some cancers are affected by acquired genes, even if there is no genetic history of cancer in the family, various bad lifestyles and poor diets in life will also increase the risk of cancer.

3. According to statistics, in addition to some cancers related to genetics, most cancers are directly related to obesity, and about 4% of cancer cases are related to obesity.

Related, especially the type of abdominal obesity, the risk of cancer is higher.

It can be seen that cancer does have a certain relationship with genetics, but it is not necessary that cancers with genetic predisposition can occur. Most cancers are affected by acquired factors, and the best way to reduce the incidence of cancer is to get regular cancer screening, maintain a good lifestyle and diet, and prevent cancer from occurring.

First of all, the answer is: yes, cancer is hereditary! Studies have found that at least 22 types of cancer are genetic disorders that run from generation to generation. That is, if a sibling gets these cancers, the risk of other siblings getting the same cancer increases by 33%.

But different cancers have different genetic risks. At present, common cancers with high heritability include breast cancer, bowel cancer, nasopharyngeal cancer, gastric cancer, liver cancer, etc., such as 20% and 30% of colorectal cancer patients have a family history of various cancers.

And if there is no genetic history of cancer in the family, the chance of developing cancer may be smaller than that of people with a genetic history of cancer. However, in addition to genetics, cancer is also related to lifestyle, emotion, and stress.

Therefore, cancer prevention should start with a healthy and regular lifestyle, maintain a good attitude, and for people with a history of cancer in the family, it is necessary to have regular cancer prevention check-ups, once found, cancer can be nipped in the bud.

Cancer is only partly influenced by innate genes, and the acquired lifestyle also has a huge impact on the risk of developing cancer. Of course, it does not mean that you can avoid cancer completely with moderation, but all other things being equal, people with a good lifestyle will definitely have a lower risk of developing cancer.

1. Keep a moderate figure, not too obese.

According to statistics, there are about 20 types of cancer that are directly related to obesity, and 4% of cancer cases worldwide are related to obesity, especially the type of abdominal obesity, and the risk of cancer will be higher.

2. Don't smoke or drink.

Smoking has been confirmed by various medical and health organizations to cause cancer, and is an important risk factor for several types of cancer, such as lung cancer, oral cancer, esophageal cancer, cervical cancer, and pancreatic cancer. Recent studies have also found that alcohol also increases the risk of cancer, even if it's just for a sip.

Therefore, people who can stay away from tobacco (including secondhand smoke) and alcohol are less likely to develop cancer.

3. Eat less sweets.

Smoking and drinking are mostly men's habits, and many women may think that they are safe from now on, but otherwise, women's favorite sweets also have a certain risk of causing cancer. Because sweets can accelerate the growth of bacteria and worsen inflammation, and chronic inflammation is often a cause of cancer, eating less sweets can also reduce the risk of cancer.

4. Stay away from bad eating habits.

There are many bad eating habits that can easily induce cancer, such as eating late night snacks often increases the risk of stomach cancer; Eating spicy and drinking hot tea increases the risk of esophageal cancer; Eating barbecued and fried foods will lead to more carcinogens and increase the incidence of various cancers.

To put it simply, if you have a light taste and eat more fresh, less processed food, you can also stay away from cancer.

5. Ensure adequate and high-quality sleep.

The onset of cancer has a lot to do with hormone levels in the human body, and ensuring adequate and high-quality sleep is an important guarantee for stabilizing the endocrine system. Not staying up late and ensuring sleep time also plays an important role in preventing cancer.

The relationship between cancer and heredity is not particularly large, because cancer is generally not hereditary, and the chance of getting cancer is relatively small, but it is not excluded to get cancer, because the daily life rules and daily living environment will also determine whether you can get cancer or not.

Yes, cancer is very closely related to genetics, if your father or mother has cancer, there is a high chance that it will be passed on to you. No, cancer has a lot to do with your lifestyle and diet, even if you have no genetic history of cancer in your family, the chance of getting cancer is relatively high.

There is a big relationship between cancer and heredity, and if there is cancer in the family, it will be passed on to the next generation. The chance of getting cancer is smaller, but that doesn't mean you can't get cancer.

Most cancers are not inherited, but a small number of cancers do, such as:

Breast cancer: If the mother has breast cancer, the daughter is 2 to 3 times more likely to develop breast cancer than a normal woman. Mu Chi Bi.

Nasopharyngeal carcinoma: Nasopharyngeal carcinoma has a clear racial predisposition, regional clustering, and familial tendency.

Gastric cancer: The appearance of gastric cancer has a lot to do with heredity, and there is obvious familial aggregation. If at least two people in a family for one or two generations have the disease, and one person is younger than 50 years old, and all patients are diffuse, it may be hereditary stomach cancer.

It should be noted that heredity does not mean hereditary disease, but the probability of heredity is higher than that of the general population. Therefore, even if someone in the family has cancer, it does not mean that all people will inherit the same disease, because cancer is a polygenic genetic disease, in addition to genetic factors, it is also related to acquired environment, lifestyle, dietary habits and other factors.

Carcinoma generally refers to cancer. Usually, cancer runs in families. The specific situation is analyzed as follows:

Cancer is generally a malignant tumor originating from epithelial tissue, and most of them refer to all malignant tumors, and cancer patients generally have symptoms such as lumps, pain, bleeding, and ulcers. If the parents are cancer patients, their children are relatively more likely to have cancer, so the cancer has a certain family inheritance.

If the patient has cancer, surgery is the first method of choice, and the patient can be treated with prophylactic hand surgery, biopsy surgery, tumor resection surgery, etc.

Statistics show that about 5% of cancers are related to heredity, such as colon cancer, gastric cancer, breast cancer, adenocarcinoma, primary liver cancer, optic retinoblastoma, neuroblastoma, etc., all of which have a certain genetic predisposition.

If the father has these cancers, there is a tendency to pass them on to his children. However, the hereditary nature of cancer is different from that of ordinary genetic diseases, and it is not passed down from generation to generation in the family but is a kind of inheritance of cancer susceptibility, or this inheritance is a tendency to predispose to a certain tumor, for example, in the family, the children have the same eating habits as the father, and the model has the same living environment, so it is also susceptible to this tumor.

Introduction: Cancer is a very terrible disease, because there are many cancers that are developing, and it is difficult to treat after the middle and advanced stages, and it will also cause great harm to people's health. However, there are also some people who worry about the hereditary condition of cancer, and some people say that it is true that cancer is inherited.

In fact, from the pathogenesis of cancer, it is mainly because of the lesion of the cellIn this process, there are some changes in the normal cells in the body, which will cause the cell to wither on its own in the process of growth. And it will cause other cells to inherit this gene, so the cells will continue to multiply and cancerous cells will appear. There are some families that do have obvious genetic symptoms of cancer, such as stomach cancer, colorectal cancer, breast cancer, these cancers will have a certain family inheritance, for example, your grandfather or grandmother has this cancer, or your aunt and uncle have such cancer, then you may also have such cancer.

The main reason is that some people carry inherited genes, which can lead to cancer. However, the genetics of cancer are also related to the environment, and some people are more likely to have certain cancers than other groups because they carry related genes, but this is not a definitive situation, it can only be said that they are more likely to develop it.

Whether it is marriage or daily life, if you say that many people in your family will suffer from the same cancer, then you should pay attention. For example, if you have colorectal cancer, you should have colonoscopy so that it can be detected and treated early. In addition, it is necessary to pay attention to the improvement of lifestyle habits, because there may be more cases of cancer in some areas, because of poor lifestyle habits.

For example, if you like to eat hot food, then you may have esophageal cancer, and in this process, you must improve your eating habits and living habits, so that you can better harvest a healthy body.

This is true because some cancers are hereditary and therefore hereditary.

Of course not. Cancer is not a genetic disease, so we must not believe rumors.

This is not true, because cancer is not hereditary, and there is a scientific basis for this, so we must look at it rationally and never speculate.

Liver cancer is one of the most common cancers, and the heritability of liver cancer has also attracted much attention.

China is a country with a severe incidence of liver cancer, which is inseparable from the high incidence of hepatitis B virus in China, and statistics show that 85% of liver cancer patients in China carry hepatitis B virus. And this virus is spread in families, therefore, it causes the familial clustering of liver cancer, so if parents are found to be liver cancer, then children should be vigilant, because you have become a high-risk group for liver cancer.

If there is a liver cancer patient in the family, the children should have a comprehensive liver examination regardless of whether they are in good health. If it appears suddenlyUnexplained weight loss, right subcostal pain, darkening around the eyes, fatigueWhen you have symptoms, you should go to the hospital in time to check for liver cancer.

To understand this issue thoroughly, it is important to understand that the causes of cancer are complexSome cancers are mainly related to environmental factors, some may be genetically related, some may be purely random, or a combination of these factors. Even environment-related factors are not a single factor, but the result of a combination of multiple factors.

The occurrence of cancer has a certain familial aggregation phenomenon. Familial clustering is when two or more relatives in the family have had similar cancers. The same is true for lung cancer, which runs in families, but is not directly passed on to the next generation.

Malignant tumors are very different from monogenic inherited diseases, although the occurrence of cancer is related to genetics, but the mechanism of cancer is extremely complex, and the correlation with genes is only one of the smaller aspects, so the next generation of lung cancer patients may have a higher chance of developing lung cancer, but not necessarily cancer.

The process by which cancer cells spread throughout the body and cause the disease to get out of control is called metastasis.

Cancer cells are also a part of our body that are formed by mutations of ordinary cells. Normal cells like to grow in groups, while cancer cells are like disobedient teenagers who run away from home willfully.

HumanCirculatory (blood) systemwithLymphatic systemIt is like a network of highways, connecting the organs of the whole body and maintaining the normal physiological functions of the human body.

These cancer cells that have broken away from the main body of the primary tumor and wandered to wander are hitching a ride on blood and lymph along the highway network in search of any "new home" where they can "take root and sprout", and once the conditions are right, they are thereOrgans and tissues away from the primary lesion are encamped, the formation of new tumors.
