Chen Lao asked heredity?

Grandpa couldn't answer.

From a scientific point of view, the answer is definitely no, but Chen's mother and aunt both have a history of nasopharyngeal cancer, and the prevalence of family members is ridiculously high.

Zhou Shouming is not a front-line doctor after all, although the old man adheres to the attitude of 'living to learn from the old', but the information contact level is not comprehensive enough, and the position in which he is located represents the contact level......

Decades of old Chinese medicine, medical dialectical ability must be very strong, regardless of the fact that nasopharyngeal cancer patients are mainly concentrated in coastal areas such as Liangguang and Dafuku, but only the number of cancer patients that grandpa can contact is pitiful.

Zhou Shouming looked at his grandson and knew that he would not be untargeted, so he asked: "Do you know anything about this? ”

Zhou Yi nodded, organized the wording slightly, and said what he knew: "Nasopharyngeal cancer is mainly concentrated in the south, the south is higher than the north, and in the south, the incidence rate in the coastal areas is higher than that in southern Hunan and western Xiangxi. ”

"There is such a thing as hereditaryness, but it is not a direct genetic inheritance of cancer cells, that is, if the parents are sick, they will not be directly transmitted to the next generation, but what is inherited? Susceptibility, easy to infect. ”

"In addition, the yellow race is the main group of the disease, the prevalence of white people is low, someone has done a special survey, 80% of the patients with nasopharyngeal cancer abroad come from the overseas Chinese group, and the study proves that the prevalence has not decreased after immigration. ”

"And when white immigrants to Southeast Asia were surveyed, there was also a trend of rising prevalence, a full 60 percent. ”

One wonders why there are no blacks in the survey?

Although blacks are distributed in various countries, the largest base still comes from Africa, which is the place with the lowest prevalence and treatment rate of various diseases, and the medical system is extremely backward.

Fortunately, Grandpa and Chen Lao didn't ask about it, and their attention was only on the prevalence.

"To sum up the above two points, we can get the results of genetic predisposition and geographical concentration, and the increase in the prevalence of white immigrants to Southeast Asia actually points out environmental and dietary factors. ”

"Old Chen, I don't know if you've heard that 'salted fish' is the culprit of nasopharyngeal cancer?"

When it comes to nasopharyngeal cancer, it would be too to say that you believe in your fate.

Judging from the incidence rate, doesn't that mean that the lives of people in the north are much better than those in the south? Lao Guang is simply sad, the 'son of nasopharyngeal cancer' chosen by God.

Therefore, in the final analysis, the origin of disease is inextricably linked to living habits and customs.

Anyone who has been to the south knows how prosperous the work market in the south is, and all kinds of seafood work are most common in the hard salted fish that exudes a strong salty taste, and the price is not cheap, and a lowest-grade mackerel costs 70 or 80 yuan a catty.

If someone has been to the islands around Laoguang, they must have a deep impression of this kind of work market, which is full of salted fish, red, green, black, large and small.

After the development of tourism, the biggest income increase for the islanders is not the folk customs and catering, but the sale of such dry goods.

Put the rice on the pot, cut a piece of salted fish and put it on the plate before lidding, spread the ginger shreds under the salted fish, pour cooking oil, and steam it with the rice, a family of three can eat a pot of rice with the salted fish, and the only side dish is a pot of rolling vegetable soup.

Regional dietary habits are an important reason for the increase in the rate of large-scale diseases.

Chen Lao nodded and wrote: "It turned out that he was poor and couldn't afford to eat vegetables, so every family used salted fish for dinner, but after getting sick, the doctor said not to eat it, and the patient also said that salted fish causes cancer." ”

Yes.

The year before last, 'salted fish' had been listed as a class of carcinogens by the WHO, and carcinogens were divided into three categories -

The study of three types of carcinogens and carcinogenic components is not clear, but there are risks.

Class II carcinogens, which have a carcinogenic risk but are not necessarily carcinogenic.

A class of carcinogens, which clearly indicates that the probability of carcinogenicity is greatly increased.

The most ironic thing is ......

The 'salted fish' suffix also has a special Chinese-style.

What do you mean?

Chinese-style salted fish, in fact, is more accurate to say Cantonese salted fish.

Together with it, there is also betel nut, which is not unfamiliar to everyone, which is a type of carcinogen in the food category, and it is really hard to imagine that these two types of things are several of the best-selling commodities in the south, radiating hundreds of millions of people.

Zhou Shouming was a little abrupt: "Therefore, the disease is still related to the eating habits of the group, the ancestor is right, the disease comes from the mouth." ”

A family's eating habits are bound to be the same.

There are also scientific research results that show that the same type of prevalence in the same family is very high, and lifestyle habits and dietary habits are the main reasons for all this.

Chen Lao's eyes looked at Zhou Zhou in a daze, the topic ended, although he knew the general theory of nasopharyngeal cancer, but the problem was that this matter did not seem to have any direct connection with his condition, and he was already very aware of his current diet.

Does the so-called family history have anything to do with him?

Elder Chen was thinking about ......

Chen Jiali came back, carrying a plastic bag in his hand and buying a lot of warm hot drinks.

Several people turned their eyes to the past, only to see that he had paper balls stuffed in his nostrils, his face was unpleasant, and seeing everyone looking at him, he said helplessly: "Oops, nosebleeds, embarrassment, there are always so many times a month......

Old Chen's eyes suddenly deepened, as if he was deep in thought.

Zhou Shouming was the same, staring at this Boss Chen, and some kind of clue emerged.

On Monday, his heart rate increased, and he could feel the change in the atmosphere, saying so much, and diverting the topic, didn't it just arouse the idea of grandpa and old Chen?

Susceptible people, susceptible races, from susceptible areas, with susceptible eating habits.

Moreover, he had a nosebleed.

There are always a few times a month!

"You say, how many nosebleeds do you have a month?" Zhou Shouming suddenly asked.

Chen Jiali nodded: "Not much, two or three times, you know herbal tea, right? We have it in the south, but we don't have it in Qinzhong, and it's easy to bleed from the nose when it's hot." ”

Who knows, Chen Lao was panting desperately, and the tracheal intubation kept making a 'wheezing' sound, so anxious that he wanted to speak, and his fingers were raised and kept waving on Zhou Shouming and his son.

Zhou Shouming took a deep breath, he felt that things would definitely not be so coincidental, but after talking so much, his heart felt like a shadow was cast.

Grandpa stepped forward and pulled off the paper ball from Chen Jiali's nostrils.

"Flashlight, turn on the flashlight!"

Zhou Zhou took out his mobile phone very quickly, turned on the flashlight and handed it over, and his grandfather pushed Chen Jiali's chin and made him raise his head.

Chen Jiali was stunned.

I wanted to open my mouth to exclaim, but I didn't dare to move, Old Man Zhou's expression was too serious.

Prenasal examination is the easiest way to diagnose nasal diseases.

When Grandpa saw this, his expression became more and more heavy, and he pinched Chen Jiali's nose: "Does it hurt?"

"It hurts. ”

"I said inside the nose, does it hurt? not outside the nose. ”

"I don't know. Chen Jiali didn't know what the old man wanted to ask, and he didn't know what kind of pain the so-called pain was, the whole person was blindfolded.

Grandpa took a deep breath and shook his head: "Go and check, there is an abscess at the bleeding point, and if it doesn't hurt, it's not a boil caused by fire." ”

Spontaneous boils are caused by a fire and can be painful to come out.

And Chen Jiali, the abscess has caused intranasal bleeding, and his grandfather deliberately pressed him and he didn't know if it hurt, which was enough to explain the problem.

Grandpa looked at Old Chen: "Slow down the matter of the old brother for a while, and make your son's problem clear first." ”
