Middle-aged women because of smoke causes lung cancer risk increased three-fold?
"Cooking 1 hour = suck half a pack of cigarettes?" Recently Network Previous entitled "Long-term exposure to high temperatures in older women smoke, becoming a high risk of lung cancer," the topic has aroused public concern and hot. The Post said "A survey of Tongji University Shanghai Cancer Institute found that middle-aged women because of long-term exposure to high temperature smoke, the risk of suffering from lung cancer increased 2-3 times. Survey showed that risk factors for lung cancer in non-smoking women in More than 60% of women long-term exposure kitchen fumes; 32% of women prefer to use high-temperature cooking oil for frying foods, while the doors and windows closed or poorly ventilated kitchens "Many users have reproduced, the more users that" this life is not. cook, love to marry do not marry. "
Can not identify the cause of one-sided only a single factor causing
In this regard, the First Affiliated Hospital of Guangzhou Medical Director of Thoracic Surgery Yanwei Jiang said that the current on the clinical point of view, the proportion of women suffering from lung cancer than ever before how to improve, an increase of about 10%, which account for a great proportion of middle-aged women. But it does not overly mechanistic understanding of cause are due to smoke, he said whether it is cancer or other malignancies, may have been dropped from smoking, immune function, and more long-term effect of psychological factors as a result of emotional results. Even relatively clear for some cause, the result is relatively recognized carcinogenic risk factors, it can not be determined unilaterally cause only a single factor.
Indeed fumes are carcinogenic factor "cook husband", "Stew" need attention
Best little contact with fumes
For online now "cooking 1 hour = suck half a pack of cigarettes?" Saying, Yin Weiqiang director, said from the chemical composition, the soot and smoke are very different, so the above statement is no comparability. However, cooking fumes produced when really no benefit to human health, especially for the upper respiratory tract and nervous system causing great harm. Also, the chemical composition as well as smoke carcinogens contained in, or a small amount of exposure is good.
Experimental results show: Harmful fumes
Some experts have done experiments found that if the oil is heated to 150 ℃, the main component of soot is generated - acrolein. Acrolein has a strong spicy flavor of the nose, eyes, throat irritation mucosa relatively strong, may cause rhinitis, laryngitis, bronchitis and other diseases. It was found that oil, rapeseed oil, soybean oil heated to 270 ~ 280 ℃, the mist produced condensate may cause chromosome damage, may cause cancer. Some people also like to make cooking oil burning up, then the oil can reach 350 ℃, this case is more harmful to health, except possibly induce respiratory diseases, but also has the potential carcinogenic risk. Generally, if the oil has smoke described oil has reached the limit, when the smoke is the largest of harmful substances.
How should reduce soot damage?
"Also a lot of people like to cook with hot oil when frying, while the kitchen doors and windows closed, small kitchen fumes polluting the environment. Thus fumes lingering high temperatures, toxic fumes stimulate the eye and throat, long-term inhalation can induce a large number of . lung carcinogenesis, "Yin Weiqiang said that improving the kitchen environment and good cooking habits is an important way to prevent lung disease: be sure to ventilate the kitchen, it is best not to stay too long in the kitchen; far less choice of fried, fried, explosion Such speculation cooking; purchase hood best choice for some big power some smoke fumes, little better quality.
Cough, cold cure after frequent recurrence of lung cancer experts advise should be careful
Why topped the mortality rate of lung cancer?
Just a few days ago, the Guangzhou Municipal Center for Disease Control released the latest cancer Surveillance, located in Guangzhou City, the mortality rate and the first incidence of malignant tumors are lung cancer, lung cancer why so fierce? "Lung cancer has a high mortality rate mainly because of advanced lung cancer when 2/3 of the patients found." 殷伟强 that patients do not have symptoms until it re-run, because the disease often develop into cancer in late stage clinical signs, For example, coughing up blood, chest pain, severe irritating cough, breathing difficulties. "Once the proposal for more than one patient, while two symptoms, or there are frequent relapses after cure of respiratory disease, sudden swelling of the hands and feet joints, it must pay serious attention, a CT scan as soon as possible." Only about 15 percent of before getting lung cancer can spread to nearby lymph nodes or other parts in the early diagnosis of cancer, no lymph node metastasis in patients with lung cancer 5-year survival rate can reach 50%.
Once every two years over 45 years of low-dose spiral CT
Yin Weiqiang said that in itself is a form of lung very uniform in imaging, once the probability of the emergence of the shadow of lung cancer is relatively large. In fact, many of the early diagnosis of lung cancer are more accidental, was doing when checking other diseases are found, such as heart disease, pneumonia need to do imaging studies, bronchoscopy, cytology cancer. So Yin Weiqiang suggested that the high-risk population of lung cancer, such as 45 (40) years of age or older smokers, long-term exposure to high temperature fumes chef, cook, etc., should be conducted every two years of low-dose spiral CT.
Comprehensive treatment of lung cancer has been the main
Early surgical treatment of lung cancer, and more comprehensive treatment of advanced
The timely treatment of lung cancer, in a very large extent, affected the patients with advanced lung cancer can live either problem. Yin Weiqiang director, said patients with early stage lung cancer can be treated through surgery, directly to the cancer resection, recurrence rate can be reduced to 10% -20%, and even the possibility of cure. "Once patients with advanced lung cancer drag, the likelihood of surgery becomes low, the recurrence rate of cancer will shoot up to 50% -80%. Present for such patients with advanced lung cancer, the treatment is also integrated treatment, usually based on the patient's condition is different with different treatment options if there is no surgical conditions, patients relapse after treatment or surgery, mainly through medical treatment, such as in combination with chemotherapy, biological targeted immune therapy.
Lung cancer early, middle and late rationalization diet, but also help restore critical condition. General early, middle and late lung cancer patients whose digestive functions are relatively healthy, cancer diet should be adequate nutrition for the main purpose to improve patient physical fitness, increase endurance. Therefore, Yin Weiqiang encourage patients with lung cancer and more nutritional intake, a balanced diet, eating more protein-rich foods such as soy products, eggs, meats, fresh fruits and vegetables and so on. It should be noted that, after as little as possible to densely populated areas, can go out wearing masks, to prevent infection.
