On February 4, 2018, this is the 18th World Anti-Cancer Day. The International Union Against Cancer (UICC) has set the theme of World Anti-Cancer Day for three consecutive years (2016-2018) as: "We can, I can beat cancer (WE CAN, I CAN)." This is an unprecedented event. From a point we can feel the determination of modern medicine for cancer treatment. However, in recent years, cancer patients are getting more and more and younger, which is an indisputable fact. In China, lung cancer is the “double champion” of cancer morbidity and mortality. It is the kind of cancer we need to pay most attention to at present.Disposable Vape, Electronic Cigarettes, vape
What are the common pathogenic factors of lung cancer?
The lung is a respiratory organ, and the common pathogenic factors of lung cancer are naturally closely related to the inhalation of breathing. Currently, there are three types that are closely related to our lives: smoking, environmental pollution and occupational exposure.
Tobacco is the first cause of lung cancer. The International Agency for Research on Cancer of the World Health Organization also clearly states that tobacco is a type of carcinogen (a type of carcinogen is a substance or mixture that has a clear carcinogenicity to the human body). The longer the smoking period, the higher the amount, the higher the risk of lung cancer. The smoke here is not only the first-hand smoke, but also the second-hand smoke and the third-hand smoke (the smokers remain in clothes, walls, carpets after smoking). Furniture and even tobacco residue on the surface of hair and skin). At present, the scale of smokers in China has exceeded 300 million, and the smoking status of the population has become a major factor affecting the incidence of lung cancer.
Environmental pollution includes both air pollution and indoor pollution. Air pollution mainly comes from motor vehicle exhaust, heating and industrial burning waste. Indoor air pollution includes tobacco smoke, domestic fuel, cooking fumes, and decoration pollution. These polluting gases contain varying degrees of carcinogens, and the possibility of lung cancer is increased by prolonged breathing of contaminated air.
Occupational exposure is also an important cause of lung cancer. There are currently evidence that occupational exposure factors that increase lung cancer include asbestos, dust, ionizing radiation, inorganic arsenic compounds, tar, polycyclic aromatic hydrocarbons in petroleum, and a variety of metals and non-metallic compounds. In general, occupations such as miners and painters in industries such as coal mining, processing, and construction are prone to lung cancer because of inadequate occupational protection measures.
How long does it take for lung cancer to decrease after smoking cessation?
With the change of health concept, more and more smokers began to quit smoking, so what happens to the incidence of lung cancer after smoking cessation?
The occurrence of cancer is to be hit twice. The first attack has caused a mutation in one of our genes. At this time, no cancer will be formed. It is necessary to attack this gene for the second time to become cancer. This second blow is a random process that can occur at any time, but smoking is the culprit in this random process. "After quantification, we will know that every 10 cigarettes smoked may cause a change in a gene in our body." After quitting smoking, it must take 10 years, and the incidence of cancer will fall to the same level as ordinary people. This is a slow process, but from the moment you quit smoking, the likelihood of cancer is slowly decreasing.
What are the symptoms of early lung cancer?
The mortality rate of lung cancer is high, and one of the reasons is that nearly 80% of patients are already in the middle and late stages when they are discovered. Frankly, early lung cancer has no symptoms. People often say that chest pain, cough, hemoptysis, joint pain and other symptoms are symptoms of advanced lung cancer. If you do not pass a professional examination or screening, it is difficult to find early lung cancer.
Who should regularly screen for lung cancer?
Regular smoking screening should be done for people with a history of smoking, a history of family cancer, miners, long-term exposure to radioactive materials, and people living in areas with serious environmental pollution. In addition, people who are not sick for more than a decade or two are also at high risk, and need to undergo an annual physical examination.
The healthy population is screened for lung cancer after the age of 55, and some lung cancer high-risk areas or high-risk groups should be screened for lung cancer after 45 years of age. It is best to choose a low-dose spiral CT examination because it finds that the early problems are much higher than the average chest radiograph (the chest radiograph may wait a few centimeters or more to be found).
In early lung tumors, if invasive, the cure rate can reach 70% to 80%. If it is non-invasive, the cure rate may even reach 100%. Even advanced lung cancer, after reasonable treatment, usually has a survival period of 3 to 5 years.
With the development of medicine, new breakthroughs have been made in the treatment of cancer. Many types of cancer treatment have already reached the medical cure standard, and even some cancers have already appeared vaccines, such as cervical cancer that has just been listed in China some time ago. vaccine. I believe that cancer will no longer be an "incurable disease" in the future.
