The weather is getting colder, especially the cold wind in the morning makes people not want to go out, so many people have begun to give up their morning jogging plan, but Mr. Wang, who is already 67 years old, still insists on exercising every day.
However, after all, it is and the body's resistance is not as good as that of young people. Once, after the exercise, Mr. Wang developed and coughed . After his children knew about it, they immediately took Mr. Wang to the hospital because was not the first time Mr. Wang coughed .
It turned out that as early as 9 years ago, Mr. Wang had already developed symptoms of coughing. After going to the hospital for examination, he learned that he had early lung cancer . The doctor suggested that he undergo surgery for . But at that time he did not consider because there were no other symptoms except cough, so he refused to operate , and was 9 years old.
Considering that Mr. Wang has had many years of smoking history, the doctor suggested that Mr. Wang have a chest CT scan. As expected, the examination results showed that Mr. Wang had a " red date" mass in his left lung lobe. After a series of examinations, Mr. Wang was initially diagnosed with advanced lung cancer .
Uncle Wang never expected that the 9-year-old cough was not an ordinary cold , but was caused by small cell lung cancer .
You may be confused when you see this, what is the relationship between small cell lung cancer and lung cancer ? Next, let’s learn about lung cancer that you don’t know.
1. How fast does lung cancer develop? And how did it happen?
In fact, the small cell lung cancer that Mr. Wang suffers from is also a type of of cancer. In addition, lung cancer also includes non-small cell lung cancer . It is worth noting that compared with non-small cell lung cancer, small cell lung cancer has a high malignant .
If it is late-stage small cell lung cancer , its five-year survival rate is less than 1% , and its two-year survival rate will be less than 10% . Such a number is enough to make people frighten.
Even if the survival rate of lung cancer is so low, there are still many lung cancer patients in life who don’t care about , especially when lung cancer is still in the early stages, the accompanying symptoms such as cough and fever are easily confused with and cold and will not attract the attention of patients. However, by the time of examination, it has become lung cancer stage .
But don’t misunderstand that lung cancer does not necessarily take 9 years to develop from early stage to late stage.
This is because everyone's physiological and physiological are different. Some early cancer patients have slow development of , while some patients are diagnosed with early lung cancer, but there is a chance that they will become late in a short period of time, and even directly endanger life .
Therefore, we must know how lung cancer occurs in order to sound the alarm bell in future life.
Are there anyone around you who have been diagnosed with lung cancer because of smoking for a long time? In fact, lung cancer is closely related to smoking, because the smoke produced by ignition of cigarettes, there are more than 13,000 toxic and harmful chemicals of .
, benzopyrene , nicotine and small amount of radioactive elements all have the effect of carcinogenic , and the carcinogens in these smoke will repeatedly stimulate bronchial mucosa and glands. For a long time, the risk of carcinogenic will become higher and higher, which is easy to cause squamous epithelial cell carcinoma and to differentiate small cell carcinoma .
In addition, some people will engage in special tasks, such as exposure to petroleum asphalt , formalin , etc., and will also increase the risk of cancer.
In fact, petroleum asphalt is the remaining by-product after oil crude oil fractionation, and has good anti-corrosion and waterproof characteristics . Although it has such a great effect on industry, its damages to the body is not small, especially the smoke produced after heating it, which has a certain stimulating effect on skin and upper respiratory tract .
A scholar once used 0 to perform experiments to control the amount of asphalt smoke inhaled by each mouse. The final pathological results showed that bronchial mucosa cilium disappeared , epithelial atrophy and necrosis , cell swelling , etc., so its damage to the human body is self-evident.
or above are two factors that cause lung cancer . However, after knowing the cause, you must also understand the corresponding symptoms of in order to judge early and promptly detect physical discomfort.
Just now we learned that Mr. Wang refused the operation because has no discomfort in except for coughing . In fact, there are many patients with early stage lung cancer, and does not even have when they cough. This is because the lung is a very special organ, , which does not have the fibers used to feel, so it is difficult to feel pain and irritation, and generally there will be no symptoms.
Take Uncle Wang’s cough symptoms as an example. Cough is actually a protective measure. If bacteria invade, our body will turn on the automatic defense system to help the lungs clean up these harmful substances. But we must learn to judge that if the cough cycle of is too long, , we must be alert to whether it is a precursor to lung cancer.
2. Be careful! There are 6 symptoms in early stages of lung cancer
However, don’t think that lung cancer will only cause cough. In fact, when early stages of lung cancer occur, the body will issue warnings . Do you know which 6 are there?
.Cough
Above we mentioned that early lung cancer patients will have symptoms of coughing, and when the tumor occurs in near the bronchus of , will aggravate the symptoms of . In fact, cough is a classic symptom of early lung cancer. At the same time, coughing can also show characteristics such as paroxysmal and irritating .
Usually, patients will feel that sputum coughs . If secondary infection occurs at this time, it will lead to symptoms of coughing sputum . However, there will also be cases where has blood in sputum. The main reason is that capillaries on the surface of the tumor are very rich in . Coughing will damage on its surface, causing blood vessels to rupture , causing blood in sputum, and generally the attack time is relatively long.
We need to pay attention to that there are actually two types of cough caused by lung cancer. One is central lung cancer cough , which is mainly paroxysmal dry cough with basically no sputum; the other is peripheral cough , but this summary rarely occurs in the early stage.
. chest pain , chest tightness
cough is easy to detect, but for women during menstruation, chest pain and chest tightness are difficult to detect. In fact, nearly half of lung cancer patients experience this condition in the early stage, especially peri-type lung cancer . chest is its first symptom . This is actually caused by cancerous tissue infiltration of the pleura.
However, chest pain also has different feelings of . Common manifestations of dull pain or dull pain in the chest are not regular chest pain. If the shoulder or chest persists, it means that there is a possibility of tumor invasion near the mediastinum of the mediastinum of the lung lobe. If the tumor is close to pleura , sharp pain will occur, and it will worsen when coughing and breathing.
. Male breast hypertrophy
What we just talked about chest pain . Don’t think that only women will have . According to data, male patients have 0%~20% of . This is actually caused by the secretion of gonadotropin by cancer cells. In addition, cancer cells can also secrete chorionic gonadotropin . This hormone may cause breast tissue hypertrophy , causing breast hypertrophy .
If male shows symptoms of breast hypertrophy, it is mostly accompanied by pulmonary hypertrophy osteoarthritis , and some will be accompanied by testicular atrophy . If you are not careful, you may be misdiagnosed as ordinary breast hyperplasia . Therefore, when performing lung examinations, breast examinations must be included in the routine must-check items.
. The factors that cause fever
are diverse. The most common thing in life is fever caused by colds. Many people know that when the body's immunity decreases, it may give bacteria and viruses an opportunity to take advantage of it, but do you know? One of the factors that cause lung infection is also virus . The fever symptoms of early lung cancer are generally caused by swelling tumor necrosis , or secondary pneumonia caused by tumors.
Therefore, when fever symptoms occur, you should observe whether is caused by due to cold. If the fever lasts for a long time and you cannot be sure of it yourself, it is recommended to go to the hospital for relevant examinations in time.
. Hoarse voice
You may wonder, How can lung diseases affect sound ?
is not the case. Most lung cancer patients will gradually grow up during the course of the disease. When lung cancer metastasizes to compress recurrent laryngeal nerve , it will cause vocal cord muscles to paralyze and cause hoarseness.
If the patient's tumor causes compression to nerve and pleural , the patient will also have symptoms of armpit pain , especially at night, which will be aggravated. Therefore, if you suddenly feel hoarse, don’t think it’s just chronic pharyngitis , tonsillitis and other diseases, and see if you have other diseases.
. Finger is clubbing
Have you noticed it? The above symptoms are easily confused with other diseases, and if you do not observe carefully, it will delay treatment. Then the symptoms I will talk about next are very easy to detect in life, that is, club-shaped finger .
clubbing finger is also called drumstick finger . The first joint of the finger is hypertrophy, the nail protrudes and curves, and is often accompanied by pain. At the same time, symptoms such as wandering arthritis and may also occur. In layman's terms, it may cause to cause burning pain in the joints such as elbows, knees, wrists, ankles, and even dysfunction. If you find that you have the above symptoms, be sure to be alert to the possibility of lung cancer.
3. What you must know about prevention
Uncle Wang tells us that it may only take 9 years to early stage lung cancer to late stage , or even shorter . Once you suffer from lung cancer, you will never be able to go back to the past. As people with healthy in , we should do a good job of prevention in daily life to prevent lung cancer from taking advantage of the situation.
quit smoking
We already know the harm of tobacco, so quitting smoking should be the primary consideration for preventing lung cancer. If you quit smoking early, the damage to the body will be greatly reduced and the risk of lung cancer will be reduced, especially for male smokers.
According to a report, 0% of patients with lung cancer are smokers , and the probability of men smoking is 123 times that of non-smokers . However, there are many women who suffer from lung cancer due to smoking. Women who smoke are 2 times that of non-smokers. Therefore, in order to reduce the risk of lung cancer, quitting smoking is the first step of .
Healthy diet
A good diet is beneficial to physical and mental health, especially for patients with lung cancer, should eat a balanced diet . Three meals should be timed and quantitative . Pay attention to the combination of diet and ensure a balanced intake of nutrition. It is recommended to formulate a good diet plan and develop a healthy dietary habit .
In life, be careful not to eat too hot or moldy foods, and eat less pickled foods. At the same time, you should eat more vegetables and fruits in . This is because vegetables contain a large amount of vitamin A, which is beneficial to maintaining cell integrity in the human body and can also promote the recovery of metabolism.
Occupational protection
People who are engaged in special work must do a good job in daily protection . For example, mines in radioactive mining areas, and try to take scientific protective measures to reduce the damage caused by radiation to the body.People working in dust environment must correctly wear protective mask to avoid inhaling harmful substances, causing to worsen .
