How to stop coughing and wheezing in the late stage of lung cancer
Lung cancer is a relatively common type of malignant lung tumor clinically. Due to the different specific types of lung cancer in different populations, the symptoms experienced by patients also vary. In the early stages of lung cancer, symptoms are generally characterized by irritative dry cough, hemoptysis, breathlessness, and chest tightness. As the tumor grows and metastasizes, patients in the later stages may experience varying degrees of coughing, wheezing, and expectoration. For such patients, the first step is to provide appropriate anti-infection treatment and oral administration of antispasmodic drugs. Inhalation of medications that relieve bronchospasm can also be chosen, both of which can achieve a certain effect in relieving cough and easing breathing.
Causes of Lung Cancer
The most common cause of lung cancer is smoking, but many people who have never smoked also develop lung cancer. One possible reason could be related to kitchen fumes. Chinese cooking habits often involve high-temperature frying and stir-frying. After frying in hot oil, the higher the temperature, the more harmful substances are in the fumes, which over time could lead to lung cancer. Some patients develop lung cancer due to air pollution; secondhand smoke is also a significant cause. For example, if a husband smokes, the likelihood of his wife developing lung cancer is more than 200% higher than in the general population, indicating that smoking harms not only the smoker but also their nearest and dearest family members. Additionally, there are other potential causes including psychosomatic factors such as chronic insomnia, depression, decreased immunity, genetic factors, and more.
How to treat dry cough caused by lung cancer?
Dry cough is a very common symptom in clinical practice, caused by many factors which are also very complex. Some patients might clearly have lung cancer. Due to the presence of lung cancer lesions, patients can experience irritating dry cough as well as symptoms like hemoptysis, chest pain, and chest tightness. It is possible that some patients do not exhibit symptoms of dry cough, perhaps due to other causes. Therefore, for dry cough, we need to identify if it is caused by lung cancer, as it often requires surgical treatment to control the symptoms. Some patients with minor lung cancer who experience dry cough might be able to control it with appropriate medications. However, to effectively control symptoms of dry cough caused by lung cancer, surgical removal is generally necessary and is the ultimate treatment plan.
Is lung cancer contagious?
The occurrence of lung cancer is associated with smoking, air pollution, and working in environments such as coal mining. However, lung cancer is not contagious. Therefore, in clinical settings, family members of patients often ask doctors whether lung cancer can be transmitted through the respiratory tract. It can be assured that lung cancer is not contagious; only communicable diseases like tuberculosis can be spread this way.
Early stage lung cancer symptoms
The most common early symptom of lung cancer includes coughing, coughing up blood, difficulty breathing, and chest pain. However, when the tumor grows in the larger bronchi, it often causes an irritating cough, leading many people to mistake it for a cold. Therefore, if an irritating cough occurs, it should be taken very seriously. The second point is that as the tumor continues to grow and affects the drainage of the bronchi, there is often an increase in purulent sputum, and the amount of sputum may also increase from before. The third commonly seen symptom is bloody sputum, which might be spots of blood in the sputum, streaks of blood, or intermittent small amounts of coughed-up blood. Large amounts of blood in the sputum are very rare.
Dietary therapy for lung cancer
In the diet of lung cancer patients, Western medicine does not have the concept of "trigger foods" like Chinese medicine does. According to Western medicine, there are no specific dietary restrictions; the focus is on maintaining a balanced diet as usual, incorporating meat, proteins, vegetables, and fruits to ensure nutritional balance. Generally, lung cancer patients may experience coughing symptoms, so it is advisable to consume a light diet avoiding oily fried foods. Extremely spicy foods can provoke irritative coughing and worsen it, so they should be avoided, along with barbecued and pickled foods, and junk food. Other than that, the diet should be similar to a normal balanced diet. For patients undergoing chemotherapy, a high-protein diet is recommended, preferably consisting of steamed or stewed dishes. These can be combined with traditional Chinese medicinal herbs such as Astragalus, American ginseng, and Dong quai, which are known to boost energy and enhance resistance, thus aiding in dietary therapy to strengthen the patient's immunity.
How long can one live with lung cancer?
The survival period of malignant tumors is a topic of great concern to everyone. The question of how long one can live with lung cancer is very difficult to answer. It should be based on the patient's physical condition and the pathological staging. However, these judgments are only based on a predictive basis and do not determine how long the patient can live. If the patient does not relapse after surgery, is sensitive to radiotherapy and chemotherapy, and shows no signs of recurrence or resistance, then their five-year survival rate is naturally higher. If the patient experiences recurrence and metastasis after surgery, then the five-year survival rate is naturally lower. Therefore, the question of how long a person can live with a malignant tumor cannot be answered generically.
How to check for lung cancer?
How to check for lung cancer, firstly, for lung cancer screening, particularly in people over forty years old, especially smokers, it is recommended to regularly undergo low-dose spiral CT scans of the chest. Secondly, if a tumor is detected, it is suggested to proceed with enhanced CT scans, sputum cytology tests, or PET-CT. If it is confirmed that there is a tumor in the lungs, then a biopsy is needed. The biopsy can be performed under bronchoscopy, or transthoracic lung puncture and biopsy of living tissue can also be done, as well as biopsy of metastatic lesions or cytological examination of pleural effusion to diagnose whether it is lung cancer, the type of lung cancer, and certain immunohistochemical situations.
What tests are conducted for lung cancer?
Diagnosis of Lung Cancer: The first method can be through chest X-ray and CT scan; The second is sputum cytology examination; The third involves using a bronchoscopy; The fourth is mediastinoscopy, which allows direct observation of the enlargement of lymph nodes on both sides of the mediastinum; The fifth is to perform PET-CT, which is Positron Emission Tomography-Computed Tomography; The sixth requires a biopsy; it can be done through a transthoracic needle biopsy, or via a bronchoscopic biopsy; The seventh is the biopsy of metastatic lesions, such as subclavian lymph nodes, and lymph node metastases in the neck or axillary areas can be examined; The eighth can involve drawing cancerous pleural effusion; if there is pleural effusion, pleural fluid cytology examination can be performed; The ninth method is thoracotomy exploration; if lung nodules or lung tumors cannot be definitively diagnosed through various other methods, thoracotomy exploration can be performed.
Does lung cancer cause coughing?
The most common symptoms of lung cancer patients include coughing, followed by coughing up blood, difficulty breathing, and chest pain. When the tumor grows in larger bronchi, it often causes an irritable cough, which can easily be mistaken for a cold. As the tumor continues to grow and affects the drainage of the bronchi, secondary lung infections can occur, possibly producing purulent sputum and an increased amount of coughed-up sputum. At this time, coughing becomes quite severe. Another symptom that may appear is blood in the sputum, which could be blood-streaked sputum, or sporadic, small amounts of coughed-up blood.
