Cancer can be prevented!Share 4 “anti -cancer treasures”, or minimize the risk of cancer

For cancer, many people think that bad living habits are the “scourge” that cause cancer, such as big fish, big meat, smoking alcohol, often staying up late, etc., which may induce cancer.



However, some people may have been “suffered” -the old man next door smoked and drink for decades, but he did not have any illness; and his own habits were regular, diet healthy, and insisted on exercise, but inexplicably suffered from cancer.

This situation may mean that cancer is brought from genes -yes, cancer is inherited.

For example, “a family of several families with cancer at the same time” is likely to be related to cancer.Therefore, if you find that relatives in the family have a history of cancer, everyone will be more vigilant.

1. Does there be cancer genes, does it mean that it will suffer from cancer?

Data show that about 10%of all cancers are hereditary.A study published in the “American Medical Association” also found that more than 22 cancers are genetic diseases, which are characterized by the phenomenon of family genetic gathering.

There are cancer genes in the body, and how risk is the risk of cancer?

The so -called cancer gene refers to some specific genes. After mutation, the cell regulation will reduce or disappear, causing cells to be cancer due to abnormal proliferation.There is cancer genes in the body, which does not mean that it will suffer from cancer, but the risk of cancer has increased.

At present, it is generally believed that cancer is formed under the interaction of genetic and environmental factors.In other words, people with cancer genes usually need to suffer from cancer under specific environmental conditions.

Taking smoking and lung cancer as an example, people with cancer genes are prone to lung cancer in the environment of smoking; on the contrary, people without lung cancer genes have less risk of lung cancer.Moreover, the contribution rate of different cancer genes to cancer will also be different.Therefore, you cannot absolutely say that there will be cancer with cancer genes.

The risk of cancer to better prevent cancer.

2. 6 types of cancer are inherited to the next generation.

Among all cancers, the following 6 types are recognized as highly genetic rates:

1. Intestinal cancer

According to statistics, about 20%-30%of intestinal cancer patients have a family history of cancer.In particular, people with family adenoma polyp disease will increase the risk of bowel cancer.If you don’t want to have hereditary bowel cancer, you can first check whether anyone in the family suffers from colon polyps.

After the age of 45, it is recommended to do intestinal cancer screening and insist on regular bowel cancer until the age of 75.If there is no abnormality of the first intestinal cancer screening, you can check the feces immunochemical test once a year or the high -sensitivity feces diving blood test, or the dung DNA test once every 3 years.If the result of regular non -colonoscopy is positive, an colonoscopy should be performed as soon as possible.

2. Stomach cancer

About 5%-10%of gastric cancer belongs to hereditary gastric cancer, of which genetic diffuse gastric cancer is the most inherited type of gastric cancer.

If there are two or more people in the family in the family have a history of gastric cancer, and one of them is diagnosed before the age of 50, and the types of gastric cancer are filled with the type of gastric cancer, which is likely to belong to hereditary gastric cancer.

High -risk groups of gastric cancer include family history of gastric cancer, poor eating habits (such as old smokers, alcoholics, or people who love to eat high salt, hot food, pickled and grilled food)It is recommended to regularly screen gastric cancer from the age of 40, and perform gastroscopy every 3 years.

If someone in the family suffer from genetic gastric cancer, the screening age is to be screened to 30-35 years in advance.

3. Liver cancer

The most inherited object of liver cancer is children.If parents suffer from liver cancer, children should pay attention to preventing liver cancer, because hepatitis B virus is vertically spread, which can easily lead to liver cancer tendency to family gathering.Especially her mother has hepatitis B virus, so her children are relatively prone to liver cancer.

Liver cancer is closely related to liver infection. As long as a person in the family is infected with hepatitis B or hepatitis C, the risk of infection of other family members will increase significantly.

Regardless of physical health or not, as long as it is a child of liver cancer patients, it is recommended to go to the hospital for a comprehensive liver examination. Screening items include B -ultrasound and liver function.

People with health, fibrosis or chronic liver disease under healthy people or under 30 years of age are recommended to combine the abdominal ultrasound with AFP once a year;

People with chronic liver diseases over 30 years of age are recommended to combine the abdominal ultrasound with AFP once every six months;

There are high -risk groups such as liver sclerosis or chronic liver disease, diabetes or obesity, liver cancer family history, long -term smoking and alcohol, and the history of cancer toxicity. The abdominal ultrasound combined with AFP is recommended to do it every quarter to half a year./Or enhanced CT every six months to a year.

4. Protestant cancer

Prostate cancer also has a clear genetic tendency.

If there are 1 patients with prostate cancer in the direct family, the risk of prostate cancer will double; if the number of prostate cancer patients with more than two prostate cancer in the direct relatives, the risk of prostate cancer will increase by 5-11 times.

After men are 50 years old, it is recommended to do at least 1 PSA screening, that is, prostate special antigen detection.

5. Breast cancer

Studies have found that about 5%-10%of breast cancer are related to genetics, the family genetic rate is about 20%-25%, and the genetic rate of relatives 1 to third-level relatives can be as high as 55%-60%.Moreover, breast cancer has a clear genetic tendency and is most likely to pass to her daughter.If the mother is a patient with breast cancer, the prevalence of daughter’s breast cancer can increase significantly by 2-3 times.

It is recommended that healthy women aged 40-45 do a breast X-ray examination once a year. By the age of 45-69, it can be relaxed to once every 1-2 years.High -risk population of breast cancer should regularly check the breasts. Once abnormal symptoms are found, they must be checked in time.

6. Nasopharyngeal cancer

The family genetic rate of nasopharyngeal cancer has a high family genetic rate. Some studies have found that if there are patients with nasopharyngeal carcinoma in the family, the prevalence of nasopharyngeal cancer of other members will increase by 20-40 times.

It is recommended that ordinary people do a regular medical examination once a year.If there is a family history of nasopharynx cancer, it is recommended to go to the hospital for EB virus testing and nasal lapsex to screen nasopharynx carcinoma.

3. Prevent cancer, first start with living habits

Nearly 90%of cancers have a lot to do with the mutation of the day after tomorrow. Therefore, it is critical to develop good living habits, especially the following points.

1. Quit smoking and alcohol

Whether it is first -hand smoke, second -hand smoke, or three -hand smoke, it will hurt health and increase the risk of cancer.The same is true for alcohol. No matter how much drinking, it will affect the body. The more you drink, the higher the risk of cancer.

It can occasionally drink a small wine, but to control the amount. Men’s alcohol intake does not exceed 25 grams each time, and women do not exceed 15 grams each time, and try not to drink liquor and other wines.

2. Persist in exercise and maintain weight

Sitting for a long time is not only easy to gain weight, but also increases the risk of cancer (such as bowel cancer).Therefore, it is recommended to adhere to exercise daily, do not sit on the stand, try to control weight in the healthy BMI range (18.5-24.9), BMI is best close to 18.5.

3. Diet health

Pay attention to nutritional balance in daily diet, and eat as much food as possible, mainly grain.You can eat more fresh vegetables and fruits, milk and soybeans. Nuts, fish, poultry, eggs and lean meat should be taken in moderation to avoid smoke, pickling, fat and processing meat products.

4. Stay away from carcinogenic factor

Try to stay away from various carcinogenic factors, including professional carcinogenic environment, indoor air pollutants, over -sunlight irradiation, anxiety and mental hypertension, carcinogenic preliminaries (such as Helicobacter pylori, hepatitis B virus, and HPV virus).

Once there is a pre -cancer state, including pre -cancer diseases and pre -cancer lesions, it is necessary to timely be regulated.

In addition, if the body appears without a daen or nodule, continuous fever, weight loss and fatigue, persistent digestion abnormalities, and changes in stool habits and shape changes, it may be a signal for cancer to find the door. It is recommended to go to the hospital for related examinations as soon as possible.

Some cancers are indeed related to genetic, but inheritance is only one of the many factors that induce cancer.

And there are cancer genes that may not have cancer. Even if there is a high risk of cancer, there is a way to avoid cancer. The easiest way is to maintain a healthy lifestyle, and regular physical examination and cancer screening.
