How many of the 100 smokers will end up with lung cancer?

Ms. Song, 46, and her husband have a son and a daughter, and they usually work in their own restaurant, not to be rich, but to be comfortable. The company's main goal is to provide a solution to the problem of the problem.

Six months ago, Ms. Song began to suffer from chest pain, coughing, poor appetite, and losing weight, and was diagnosed with advanced adenocarcinoma of the right lung that had metastasized after a hospital examination. The company's main goal is to provide the best possible service to its customers.

After consultation, the doctor thought that Ms. Song's lung cancer was related to long-term exposure to kitchen fumes.

Smoking is one of the high-risk factors for lung cancer, and it is estimated that 90% of lung cancers are related to smoking, so how many out of 100 smokers will get lung cancer?

A 2004 study published in the British Journal of Cancer found that non-smokers had a 0.3% chance of dying from lung cancer at age 75, people who had been smoking had up to a 16% chance of dying at age 75, and people who smoked more than five cigarettes a day had a 25% chance of dying from lung cancer at age 75. That means that 1 in 6 smokers will die of lung cancer by age 75, and 1 in 4 people who smoke more than 5 cigarettes a day will die of lung cancer, which translates to 25 out of 100 smokers.

According to epidemiological data, about 53% of non-smoking women worldwide have lung cancer, and this percentage is as high as 86% among Chinese women with lung cancer. The data presented by Professor Guo Lanwei of Henan Cancer Hospital at the 2022 World Lung Cancer Congress showed that the proportion of non-smoking women with lung cancer in China is similar to that of smoking men.

So why are more and more nonsmokers getting lung cancer? It may also be related to the following reasons.

Passive smoking is considered passive smoking when you are in the same room as a smoker, and third-hand smoke can be left on clothing, carpets, and hair and enter the respiratory tract of nonsmokers, which may also increase the risk of lung cancer.

In addition to tobacco smoke, which is a high risk factor for lung cancer, formaldehyde, radon, benzene and other gases and radioactive substances from indoor decoration are also high risk factors for lung cancer.

When you are in the kitchen cooking food, you will produce fumes, and fumes may contain carcinogenic benzo(a)pyrene, and long-term inhalation of kitchen frying fumes may induce lung tissue cancer.

Once the lung tissue becomes cancerous, the body may show some abnormal distress signals, if there are these 4 abnormal changes in the head, lung cancer is coming.

1. Hoarseness

Lung cancer may be hoarse if it metastasizes to the mediastinal lymph nodes and invades or compresses the laryngeal retrol nerve that controls the vocal cords.

2. Coughing and coughing up blood

Coughing or coughing up blood may also be caused by lung cancer. The irritation of lung tumors to the bronchial tubes may induce coughing symptoms, mostly manifested as an irritating dry cough, so it is important to be alert to coughs that are not cured for a long time. In addition, there are blood vessels in the tumor, so if the blood vessels rupture when you cough hard, there may be blood in the sputum.

3. Facial swelling

After the lung tumor compresses the superior vena cava, it will cause superior vena cava syndrome, resulting in facial swelling, neck edema and upper limb edema.

4. Shortness of breath or wheezing

Symptoms such as dyspnea, shortness of breath and wheezing may be caused by the growth of the tumor into the bronchus leading to narrowing of the organ, especially if it is not cured for a long time must be seen as soon as possible.

Usually, the airway mucosa of the lungs secretes 50-100 ml of mucus every day to keep the mucosa moist. Once the human respiratory tract becomes infected with microorganisms or enters a foreign body, the secreted mucus increases, sticking to some of the harmful substances in the respiratory tract, sweeping them through the airway to the trachea and then coughing them out of the mouth, forming what we commonly call phlegm.

When there is a respiratory infection, the symptoms of coughing and coughing up phlegm may occur, and the different colors of phlegm that are coughed up represent different diseases.

1. White mucus sputum

Patients with acute or chronic bronchitis may cough up white mucus sputum or light white clear mucus in the early stages.

2. Red or brownish-red sputum

Red sputum may be due to the presence of blood or hemoglobin in the sputum, mostly due to tuberculosis, lung cancer, bronchiectasis, and other diseases. In addition, necrotic decomposition of lung tissue in patients with pulmonary schistosomiasis may result in brownish-red rotten peach-like sputum, patients with Klebsiella pneumoniae may have brick-red jelly sputum, and patients with acute pulmonary edema may have pink frothy sputum.

3. Yellow sputum

Yellow sputum is mostly purulent sputum, which is mostly suggestive of bronchopneumonia, tuberculosis, bronchiectasis, etc. Severe patients may also have yellow-green mucous sputum and should be alert to bronchiectasis, lung abscess, chronic bronchitis, etc.

4. Green sputum

Green sputum may be due to Pseudomonas aeruginosa infection or caseous pneumonia, atrophic rhinitis.

5. Rust-colored sputum

Rust-colored sputum may be a symptom of lobar pneumonia, usually triggered by S. pneumoniae, S. aureus, and Streptococcus pneumoniae, with diffuse fibrin exuding from the alveoli, and the patient may also have chest pain, high fever, and shortness of breath.

6. Black or gray-black sputum

Black or gray-black sputum may be due to pneumoconiosis, also known as pneumoconiosis. Black or gray-black sputum may be triggered by long-term inhalation of harmful dust induced lung tissue lesions in patients.

Different colors of sputum can reflect different diseases, and you can learn about them appropriately.
