When it comes to cancer, everyone is familiar with it, even afraid! But do you know that in our life, there are also many culprits who cause cancer? Now let’s look at a case first:

Ms. Xu, who lives in Shanghai, was diagnosed with cancer last year, but what is even more frightening is that her husband, son and father all died of cancer.

What is the reason why a family has cancer and can’t escape the entanglement of cancer? The doctor conducted a lot of data analysis and found that the cause of cancer in Ms. Xu’s family turned out to be aflatoxin.

It turns out that there is a pepper tree in Aunt Xu’s home, which produces a lot of pepper every year, and Aunt Xu especially likes to eat pepper, which is indispensable for making pies, buns or cooking.

In fact, it is very difficult to store pepper. Aunt Xu will directly put away the pepper that has not been dried, so some pepper appears damp and moldy. Moreover, Aunt Xu is particularly frugal, and will continue to use moldy pepper. The doctor said that this is because the body ingested too much aflatoxin after eating moldy pepper for a long time, which induced cancer.

As early as October 2017, the World Health Organization compiled and published a list of four types of carcinogens according to their relevance to cancer. They are:

Class 1: it is a definite carcinogen for humans;

Class 2: limited evidence of carcinogenicity to humans;

Category 3: Suspicious carcinogenicity to human beings;

Class 4: substances that may not be carcinogenic to human body.

You know, there are 120 kinds of class 1 carcinogens! Today, Xiaobian has sorted out the categories that are closely related to our daily life:

01, wine and alcoholic beverages

The intermediate product of ethanol metabolism in the body is acetaldehyde, which can cause DNA damage or double-stranded breakage in cells, thus causing cancer. Ethanol is also a good solvent, and many carcinogens will be dissolved in ethanol. Some alcoholic beverages contain carcinogenic substances such as asbestos fiber, arsenic and nickel; Carcinogens such as polycyclic aromatic hydrocarbons (such as benzopyrene) may also be produced during the fermentation and distillation of wine and alcoholic beverages. Therefore, alcohol is an important risk factor for oropharyngeal cancer’s disease, laryngeal cancer, esophageal cancer, liver cancer, colorectal cancer and breast cancer.

02. Smoking

Cigarettes contain a large number of polycyclic aromatic hydrocarbons, phenolic compounds, formaldehyde and other carcinogens, which are important risk factors for lung cancer, laryngeal cancer, lip cancer, tongue cancer, oral cancer, esophageal cancer, gastric cancer, colon cancer, pancreatic cancer, bladder cancer, renal cancer and cervical cancer.

03, second-hand smoke

In the cold smoke exhaled by smokers, the tar content is twice as much as that in the hot smoke inhaled by smokers, and the benzopyrene content is twice as much.

04, processed meat (intake)

Pickled meat contains more nitrite and phosphate, while smoked meat contains polycyclic aromatic hydrocarbons (benzopyrene). It may induce a variety of cancers and is an important risk factor for colorectal cancer.

05. Chinese salted fish

A large amount of nitrite is produced in the pickling process, which is an important risk factor for inducing nasopharyngeal carcinoma.

06. Areca nut

Areca catechu has a lot of crude fiber, which will cause continuous damage to oral mucosa and lead to cancer. The alkaline substances and alkaloids contained in betel nut will destroy the cell membrane of mucosal cells and DNA of cells. It is an important risk factor for oral cancer.

07, outdoor air pollution

It is easy to cause lung cancer, and the risk of bladder cancer will also increase.

08, diesel engine exhaust

The tail gas contains hundreds of different compounds, which have been proved to be related to lung cancer and bladder cancer.

09, benzopyrene

A chemical substance found in coal tar, which is commonly found in automobile exhaust gas (especially diesel engines), smoke produced by burning tobacco and wood, and grilled food. It is a high risk factor for lung cancer, digestive tract cancer, bladder cancer and breast cancer.

10. Benzene

Paint, wallpaper, carpets, printers, automobile exhaust, synthetic fibers, building decoration materials, wood-based panel furniture and cigarette smoke all contain benzene. The products of benzene metabolism in human body will lead to the breakage and fragmentation of DNA chain and induce leukemia.

11. Formaldehyde

Ordinary people are mainly exposed to formaldehyde through artificial boards in newly renovated homes. It can cause nasopharyngeal carcinoma, neonatal malformation, childhood leukemia, Hodgkin’s lymphoma, multiple myeloma, myeloid leukemia and so on.

12, untreated or lightly treated mineral oil

Used for making hair cream, hair oil, hair wax, lipstick, facial oil, skin care fat, etc., and also used as food additive. It is a by-product of petroleum and contains a variety of hydrocarbons. Polycyclic aromatic hydrocarbons, heavy metals and other impurities may induce cancer.

13. Solar radiation

Excessive exposure, ultraviolet rays in the sun can lead to skin cancer.

14. Ionizing radiation (all types)

It mainly includes α-ray, β-ray, proton stream, neutron stream, X-ray and γ-ray. Ionizing radiation can induce various types of DNA molecular damage, thus causing cancer. May produce induced leukemia.

15. Hepatitis B virus (chronic infection)

Hepatitis B virus can cause DNA rearrangement and DNA fragment loss, and reduce the degradation ability of liver cells to other carcinogens.

16. Hepatitis C virus (chronic infection)

Virus core protein is closely related to liver cancer.

17, human papillomavirus

At present, more than 130 subtypes of DNA virus have been isolated, which are divided into high-risk and low-risk types, among which high-risk types 16 and 18 are the main types that cause cervical cancer.

18. Helicobacter pylori (infection)

Long-term settlement in the stomach will gradually destroy the gastrointestinal wall, which is a high risk factor for inducing gastric cancer.

19. Aflatoxin

It mainly exists in moldy grain, nuts and oil products. Eating food containing low concentration of aflatoxin for a long time is considered to be the main cause of liver cancer, gastric cancer and intestinal cancer.

20, estrogen-progesterone oral contraceptives (share)

It can induce liver cancer and increase the risk of breast cancer and cervical cancer.

21, painter, painter, painter, etc. (occupational exposure)

Pigments contain heavy metals such as cadmium, lead, mercury and chromium, and paints and organic solvents contain benzene and formaldehyde. Long-term exposure will increase the risk of cancer.

note:

The carcinogens mentioned above can cause some cancers, which refers to a possibility after long-term, excessive intake or contact. If you only eat a little occasionally, or touch it occasionally, don’t worry.

This article examines the doctor:

　　CCTV News:Since the beginning of this year, there have been explosions of companies in the A-share market, such as Buchang Pharmaceutical and Xincheng Holdings. The stock prices have been falling continuously, and investors have suffered heavy losses. In the past two days, dividends have also exploded. Dividends were originally a good thing, earning money to return investors, but this dividend was the first time I saw it.

　　On the afternoon of July 19th, Fu Jen Pharmaceutical announced that due to funding arrangements, cash dividends could not be paid according to the original plan. According to the annual dividend plan of Furen Pharmaceutical in 2018, it is planned to distribute a total cash dividend of 62,715,800 yuan. The data shows that as of the end of the first quarter of 2019, the balance of monetary funds on Furen Pharmaceutical’s account was 1.816 billion yuan.

　　Some analysts in the industry believe that Fu Jen Pharmaceutical’s financial report data in recent years violates common sense and is suspected of serious fraud.

　　Furen Pharmaceutical has a thunder account of 1.8 billion but has no money to pay dividends.

　　Fu Jen Pharmaceutical announced on July 19th that due to financial arrangements, the company failed to complete the transfer of cash dividends in accordance with relevant regulations, and could not pay cash dividends as originally planned. The "iron rooster" who didn’t pay dividends for 20 years finally got a bonus last year. This year, it is clear that there are 1.8 billion monetary funds in the account in the first quarter, but even 60 million can’t be separated. I believe that after the resumption of trading, the stock price pressure will be great.

　　On July 15th, Dong ‘e Ejiao announced its semi-annual performance forecast, and its net profit decreased by 75% to 79% compared with the same period of last year. On July 12th, Han’s laser forecast net profit decreased by 60%-65% year-on-year. The market was shocked, and Baima would step on thunder, and its share price plummeted.

　　Another example is the former Xincheng Holdings and Buchang Pharmaceutical. Because the scandal of the company’s chairman was exposed, the stock price fell.

　　There are also people who are particularly concerned about Kangmei Pharmaceutical and Kangdexin. Because of their alleged financial fraud, their share prices have fallen by only a fraction. In addition, in the past two years, Shapu Aisi and Erkang Pharmaceutical, various emergencies have caused listed companies to explode.

　　The proportion of R&D in explosive pharmaceutical enterprises is low, and the sales expenses are high.

　　Further observation of so many companies that explode mines, among which pharmaceutical companies account for a lot. Simply analyzing these companies, Furen Pharmaceutical spent 230 million yuan on R&D and 820 million yuan on sales in 2018, accounting for 3.6% and 13.0% of revenue respectively.

　　In 2018, Buchang Pharmaceutical spent 480 million yuan on R&D and 8.04 billion yuan on sales, accounting for 3.5% and 58.9% of revenue respectively.

　　Generally speaking, the R&D expenses of these companies are relatively low, but on the other hand, the sales expenses are relatively high, such as Buchang Pharmaceutical. Nearly 60% of the operating income is used for sales, and I don’t know where the money has gone. Many investors believe that if products are not competitive, they can only strengthen sales and even play the edge ball.

　　Pharmaceutical companies generally have a high gross profit margin, but apart from the relevant employees, in fact, many people simply don’t understand the company, and they can’t know the actual curative effect of the products, and how the actual sales are. For example, some Chinese medicine companies have unclear curative effects due to historical reasons. Recently, many Chinese medicine injections have been restricted, and related listed companies will be affected.

　　Lujiazui view:

　　For investors, if they see pharmaceutical companies with low R&D expenses and high sales expenses, they should be careful to avoid stepping on thunder.
