Aunt Liu is 58 years old this year and has been since she was youngChronic bronchitisHaunt. 3 months ago, she appearedUnusual cough symptoms, she didn't take it too seriously, thinking it was caused by the onset of ** disease.
But the symptoms on my body are getting worse and worse, and sometimes I vomitThere is also blood in the sputum。Only then did Aunt Liu realize that the situation was wrong and hurriedly went to the hospital for examination. Upon examination, she was diagnosed withLung cancer, and the course of the disease has progressed to the middle and late stages.
This result is difficult for Aunt Liu to acceptI have never been in the habit of smoking, why did I get found by lung cancer?
1. There are more and more lung cancer patients who do not smoke clinically
In recent years, the incidence of lung cancer has become younger and younger, and the number of lung cancer cases in Nanjing Chest Hospital from 1996 to 2005 according to the Chinese Journal of Lung Cancer found that the number of people aged 50 years old who developed lung cancer in the next five years increased significantly compared with < previous five years.
Li Junling, chief physician of the Department of Medical Oncology, Cancer Hospital, Chinese Academy of Medical SciencesHe has said that lung cancer is a multifactorial disease. Among them, smoking is the most dangerous factor, but smoking is not the only ** hormone. Some don't smoke themselves, but because the people around them need itPeople who are exposed to secondhand smoke for a long time also have an increased risk of cancer
And some young people are susceptible to lung cancer, mainly related to staying up late and working overtime resulting in physical overworkThe body's immunity is weakenedand other factors. In recent years, becauseEnvironmental, dietary, and genetic factorsThe number of cases of lung cancer is also increasing.
In addition to the above factors, everyone must be vigilant against the three major lung cancer carcinogens in the daily home.
Kitchen fumes: Smoke from cooking foodBenzopyrene, volatile nitrosamines, heterocyclic aminesLong-term inhalation of these fumes will increase the chance of mutation in cells and tissues, increasing the risk of cancer.
Secondhand smoke: Some patients with lung cancer do not smoke themselves, but there are people around them who smoke, so that they let themselves be passive smokers in the environment of secondhand smoke and third-hand smoke for a long time. There are studies that have found thatBeing forced to inhale secondhand smoke is even more harmful to the body than smoking directly.
Decoration radon: Uranium decomposes in soil, rocks, and water to release radon, and long-term exposure to radon excess will significantly increase the risk of lung cancer.
2. If there are 3 abnormalities in your legs, it may be that your lungs are "crying for help"!
Clinically, many patients diagnosed with lung cancer are found to be at an advanced stage and lose the opportunity for surgery. This is related to factors such as the early symptoms of lung cancer are not obvious and easy to ignore, and the rapid development of lung cancer gives people too short reaction time.
Although lung cancer is difficult to detect at an early stage, it is not untraceable. If the patient has 3 abnormalities in both legs, it is necessary to be vigilant and it is recommended to check it as soon as possible.
1. Leg pain
Lung cancer tends to cause patients to secrete procoagulant substances, which enter the bloodstream and promote the aggregation and formation of plateletsBlood clots。When a blood clot flows through the calf, it can cause the calf to become clogged and painful. Pain in the legs, it could also beMetastasis of the lesionCompression of a nerve in the leg.
2. Abnormal legs
Traditional Chinese medicine believes that the lungs are the main fur, and whether the lung function is good can be judged by the ** state. When cancer occurs in the lungs, the gas exchange in the patient's body is abnormal, and the blood supply to the lower limbs may be insufficientCyanosis in color
3. A lump appears on the leg
The leg is normally smooth and lumpy-free, but once an abnormal lump is found in the leg, especiallyHard texture, poor mobility, and there isTendernessshould be highly suspicious of lung cancer metastasis.
In addition, likeParoxysmal cough, blood in sputum, blood in sputum, chest and back painand other symptoms, you should also be alert that it may be caused by lung cancer.
3. Early diagnosis and early treatment is the key to improving the survival of patients
How long does it take for lung cancer to progress from early to advanced stages?The development process of different pathological types of lung cancer is also different, generally squamous cell carcinoma and adenocarcinoma take 2 to 3 years, and small cell lung cancer may metastasize within 1 year, and some patients will metastasize within half a yearIn addition, the degree of malignancy of the tumor, the time of cell doubling, the physical fitness and mental state of the patient, etc., will affect the development of the disease.
ApproximatelyThe best time to diagnose lung cancer has been missed, so lung cancerEarly screeningIt is very important, and experts recommend that the following high-risk groups of lung cancer should pay special attention.
Age 55 74 years, cigarette smoking》30 packs a year, or quit smoking for no more than 15 years;
Family history of lung cancer;
Have a history of long-term inhalation of oil smoke or long-term exposure to second-hand smoke;
History of occupational exposure to asbestos, radiation, silica, etc.;
He has suffered from chronic obstructive pulmonary disease, pulmonary fibrosis and other lung diseases.
Recommended for these populations:At leastA low-dose spiral CT examination was performed once every 1 yearIf the annual screening is normal, it can be rechecked once every 2 years according to the doctor's instructions1 2 years.
The occurrence of lung cancer is related to many factors, but the most dangerous of them is smoking, and people with a history of smoking are advised to quit smoking as soon as possible. Some people who cook regularly should use the range hood frequently to avoid exposing themselves to oil fumes for a long time.
