Does lung cancer develop quickly? The prevalence of lung cancer is high, what are the causes of lung

It shouldn't be onset, there is a shadow so quickly, you should do an MRI or CT enhancement, and then you can confirm whether it is lung cancer or not?

Does lung cancer develop quickly? Yes, if you get lung cancer, the onset is very fast and very difficult to treat.

Lung cancer develops at a relatively rapid rate. Lung cancer generally has no obvious symptoms in the early stage, the onset is insidious, and it is generally found at an advanced stage.

The speed of progression of different lung cancers is different, so it is necessary to analyze the specific patients and cannot generalize, and the higher the degree of malignancy, the faster the development of lung cancer. Patients are advised to visit the oncology department of a public hospital for evaluation under the guidance of a specialist.

Squamous cell carcinoma grows at a slower rate, while small cell lung cancer grows faster. Poorly differentiated lung cancer grows at a faster rate, while well-differentiated lung cancer grows more slowly. Lung cancer grows relatively slowly in its early stages, and as the disease progresses, cancer cells multiply faster.

Patients with advanced lung cancer progress more rapidly

In fact, the incidence of lung disease is very high, if you are scientific before, you should pay attention to the regular examination in a big hospital, early detection and early ** will not appear this situation, this is negligence, so hurry up and check it again, you are sure whether it is a tumor.

Lung cancer develops very quickly, and it is possible to be killed by massage in just three months, so the incidence of lung cancer is also the highest mortality rate.

The onset of lung cancer is also very fast, especially if the body is weaker.

There are four main causes of lung cancer.

1.Air pollution.

With the rapid development of industrialization, a large number of coal plants, chemical plants and vehicles have increased, resulting in more and more exhaust emissions, air quality is getting worse and worse, and serious air pollution will occur in many heavy industrial areas, and harmful substances in the air are directly inhaled into the trachea, damaging lung function and causing lung cancer. In addition, formaldehyde in home decoration and oil smoke in the kitchen are also factors that induce lung cancer.

2.Disease. <>

Some respiratory diseases, such as bronchitis, asthma, lung cancer and other diseases, can also accelerate the occurrence of lung cancer if not timed**.

3.Internal factors of the human body.

For example, poor immunity, decreased metabolism, family inheritance and endocrine disorders will also accelerate the occurrence of cancer.

4. Smoking. Now, people are calling for the harm to your health in smoking. Please quit smoking as smoking is the most important cause of lung cancer.

Studies have shown that people who smoke more than 24 cigarettes a day are more likely to be non-smokers. The longer you smoke and the more you smoke, the greater your risk of lung cancer, so it's essential to quit.

It is true that the incidence is higher in large cities than in small and medium-sized cities, mainly because of air pollution, smoking, and high work stress. Another reason is that large cities have better physical examinations and higher detection rates. In the past, some people died without knowing it, but in fact, it was possible that it was lung cancer, and it was not detected.

There is a kind of lung cancer that is low-grade malignant, and it will not significantly enlarge and metastasize if it stays in the body for several years or even more than ten years, and there are no clinical symptoms.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Regular smoking is the biggest factor.

Early symptoms are difficulty breathing, lung pain, decreased respiratory rate, poor breathing, and low blood pressure, which are all early symptoms of lung cancer.

There will be a frequent cough, and in life, there will be loss of appetite, poor energy, and the complexion will become particularly bad. There is also blood in the cough. Weight loss will occur, and low-grade fever will often occur, making it more difficult to breathe. Chest tightness and chest pain.

Some patients have varying degrees of cough, shortness of breath or chest pain, low-grade fever, difficulty breathing, anemia, and hoarseness.

In the early stages, there may be a loss of appetite, then a loss of energy, and there will be stomach pain, and the complexion will be latte.

Experts said that at present, lung cancer has become the malignant tumor with the highest incidence and mortality rate in China. One out of every 3-4 cancer deaths is lung cancer. Experts tell us that these shocking figures remind us once again of the need to take care of lung cancer and prevent lung cancer.

Experts tell us that there are no special symptoms of lung cancer in the early stage, but only the common symptoms of general respiratory diseases, such as cough, phlegm and blood, low-grade fever, chest pain, and breathlessness, which are easy to ignore. ?According to experts, from the 70s and 90s of the last century to the beginning of this century, China has conducted three surveys on the causes of death of the national population.

According to the survey, compared with the lung cancer mortality rate in China in the 70s, the lung cancer mortality rate in 2005 has increased by more than 490%. Among the urban population, malignant tumors are the first cause of death among all people, and lung cancer accounts for the first cause of death from malignant tumors, becoming the first killer of threatening people's health. At present, in China, one out of every 4-5 people who die is from cancer, and one out of every 3-4 cancer deaths is from lung cancer patients.

The current proportion of lung cancer deaths has reached 20 to 25 percent, and it has reached 27 percent among men in urban areas, and one in every three to four cancer patients dies from lung cancer. Recommended guide How to >> cancer** **Best Hospitals for Cancer Advanced Lung Cancer** Lung cancer as a common, frequent and chronic disease has entered our lives. Experts believe that lung cancer, as the number one killer of cancer, is not only related to related factors such as population aging, urbanization and rural urbanization, but also related to the huge number of smokers and passive smokers in our country.

To prevent lung cancer, tobacco control is the primary factor. The expert's explanation of "" hopes to help every patient get rid of the disease as soon as possible. The experts of our hospital have introduced many international leading technologies based on many years of practical experience in cancer diseases, so if you want to know the content of related diseases, our experts will give you detailed answers and take corresponding methods according to the patient's condition.

The incidence of lung cancer in China is getting higher and higher, especially in Beijing, which is the first in the country. According to Mao Yu, deputy director of the Beijing Municipal Health Bureau, since 2005, the incidence and mortality rate of lung cancer in Beijing has jumped to the top of all cancers. In the 10 years from 2000 to 2009, the incidence of lung cancer in Beijing increased, with one in five cancer patients suffering from lung cancer.

Have we ever thought about the reasons for this phenomenon? Not only that, but the incidence of lung cancer in people over the age of 35 is accelerating; It is also more common in men than in women. According to the data, the ratio of men and women in lung cancer patients in Beijing is 172:

100。Authoritative departments believe that smoking is the "main culprit" of lung cancer, and more than 9 percent of lung cancer is believed to be caused by active smoking or second-hand smoke. It is worth noting that the risk of lung cancer increases by 20 to 30 percent in people who smoke secondhand smoke.

It is also believed that in addition to smoking and secondhand smoke, there are many factors that contribute to the sharp increase in the incidence of lung cancer. Some industry experts believe that the haze weather caused by poor air quality and the lack of stress resistance of urban people are important reasons for the sharp increase in the incidence of lung cancer. Why is the incidence of lung cancer increasing significantly?

**Hospitals with **lung cancer] Huxiang experts believe that in addition to smoking, one is atmospheric pollution, and the other is that there is also a lot of pollution in interior decoration, in addition, the change of lifestyle has also increased the incidence of lung cancer.

The hair of lung cancer is complex. To sum up, there are two main factors:

1. Environmental carcinogenic factors. With the development of industry, air pollution has become an important problem, such as nitrosamines, asbestos, chromium, nickel, mustard gas, arsenic, asphalt, petroleum exhaust gas and other ......Dispersed in air and water into the human body, it has become an important carcinogenic factor;

2. Smoking is the most important factor among personal factors. A smoking index greater than 400 is significantly associated with the incidence of lung cancer, and the smoking index is the number of cigarettes smoked per day multiplied by the number of years smoked. According to a study by scholars, smokers have a higher incidence of lung cancer than non-smokers.

Tobacco contains the unique carcinogen N-nitrosonicotine, which is a cyclonitrosamine, which can become a carcinogenic active substance after activation, and has the performance of carcinogenic mutations.

Primary broncholung cancer is the most common respiratory malignancy. In the history of medicine, lung cancer has been vividly compared to the plague in the 10th century and tuberculosis in the 19th century. In 1997, the mortality rate of both male and female lung cancer patients in Shanghai was the highest among all types of cancer.
