How many millimeters are normal lung nodes?
There was no standard for determining the size of lung nodes. Different literature and doctors gave different answers. According to the document [2], for lung nodes with a diameter of less than 5.0mm, it is recommended to perform a CT review every 6 months and once a year in the future. It was mentioned in document [4] that most of the lung nodes with a diameter of less than 6 mm were benign, while document [5] mentioned that the probability of malignant lung nodes with a diameter of less than 5 mm was within 1%. Therefore, it could be considered normal to have lung nodes with a diameter of less than 5 mm, but regular reexaminations were needed to observe changes.
Are there many people with lung nodes now?
Nowadays, there were many people with lung nodes. The discovery rate of lung nodes increased year by year, especially during physical examinations. Nearly 80% of lung nodes were benign, and only a few were malignant and required surgery. With the advancement of medical technology and the improvement of people's health awareness, more and more people began to pay attention to their physical health. The advanced examination technology used during physical examination could detect small diseases such as lung nodes earlier. Therefore, there were more people with lung nodes now.
How many millimeters or more does the lung node suggest surgery?
When the diameter of the lung node is more than 8mm, it is recommended to consider surgery. However, other factors needed to be considered, such as the nature of the tumor (solid or ground-glass), the patient's family history of lung cancer, long-term smoking and other high-risk factors, the malignant signs of the tumor, follow-up observation and chest CT reexamination results, etc. Sometimes, a lung autopsy was needed to determine the benign or malignant tumor before deciding whether surgery was needed. In addition, according to the size of the tumor and the probability of malignant tumor, regular follow-up examinations could also be performed without surgery. All in all, the surgical recommendations for lung nodes required comprehensive evaluation and decision-making based on individual conditions.
How are lung nodes formed?
Lung nodes were damage caused by lung tissue damage. According to the information provided, the causes of the formation of lung nodes included foreign body aspiration, inflammation, vascular disease, benign tumors, malignant tumors, and so on. Scars after infection, inhaling harmful substances, smoking, inflammation, vasular diseases, benign and malignant tumors can all lead to the formation of lung nodes. The risk of lung nodes depended on their nature. Benign nodes were usually caused by foreign body aspiration, inflammation, vasectomy, or benign tumors. However, the specific formation mechanism and cause may require further pathological testing to determine.
How to treat lung nodes
The treatment of lung nodes depends on the cause and nature of the nodes. Lung nodes can be divided into infectious and non-infectious. For infectious nodes, treatment methods include taking corresponding anti-infective treatments according to different pathogen, such as antibiotics, anti-inflammatory drugs, and antimycotic drugs. For non-infectious nodes, the treatment method was based on the pathological type to choose the corresponding chemotherapy, radiation therapy, targeted therapy, or immune suppression therapy. For benign tumors, conservative treatment was a common method, including observation and traditional Chinese medicine treatment. Surgery was a common treatment method, especially for malignant or enlarged nodes with increased solid components. However, the specific treatment plan should be judged and decided by the specialist according to the specific condition of the patient.
How to exercise lung nodes
Patients with lung nodes can exercise through some appropriate exercises. There were several ways to exercise. First of all, it was beneficial for the lungs to exercise. For example, jogging, hiking, biking, swimming, and so on. These exercises could increase lung capacity and promote oxygen intake and use in the lungs. Secondly, deep breathing and cough training could also improve lung function. Deep breathing exercises can be done through chest and abdominal breathing, 2-3 times a day, about 10-20 minutes each time. Cough training can strengthen the breathing muscles and help with phlegm production. In addition, walking was also a common form of exercise. It could exercise the whole body in an appropriate amount and improve one's mood. However, the specific exercise method should be determined according to the individual's situation and the doctor's guidance. When exercising, you should pay attention to moderation, avoid overexertion, and maintain normal breathing.
How to cure lung nodes
The treatment of lung nodes depends on the nature and cause of the nodes. The following conclusions: 1. For inflamed nodes, treatment methods included anti-infectious therapy, anti-inflammatory therapy, and antimycotic therapy. The specific treatment should be based on the selection of appropriate drugs for different pathologies. 2. For non-infectious nodes, such as nodes caused by immune system diseases or old diseases, treatment is usually not needed. 3. For the judgment of benign and malignant lung nodes, the diagnosis could be confirmed by morphological and molecular pathological tests. For malignant nodes, surgical removal was the first choice of treatment. For benign tumors, you can choose to have regular follow-up examinations to observe the changes in the tumor. 4. Traditional Chinese medicine also played a certain role in the prevention and treatment of lung nodes. It could make the nodes smaller or even disappear by clearing the lungs, nourishing the lungs, removing phlegm, relieving depression, softening hardness, and dispersing the masses. It could also comprehensively regulate the patient's physique, improve the internal environment of the human body, and prevent the reappearance of the nodes. In short, the treatment of lung lumps varied according to individual circumstances, and treatment decisions should be made according to the doctor's guidance and specific circumstances.
How many years can lung nodes generally live?
The survival time of lung nodes depends on the nature of the lung nodes and the treatment. Benign lung nodes generally did not affect one's lifespan, which was similar to that of a normal person. The survival rate of malignant lung nodes could range from several months to several years, depending on whether the patient actively cooperated with the doctor's treatment. The survival rate of patients with early stage lung nodes after surgery was generally above 90%, and they could live for many years. However, for late-stage patients, the five-year survival rate could reach 40% to 80% after surgery combined with postoperative chemotherapy. It should be noted that the survival time of lung nodes was also affected by other factors, such as the degree of malignant disease, whether there was metastasizing, and the patient's physical condition. Therefore, the specific survival time needed to be evaluated according to the individual's situation. It was impossible to give a definite number.
The causes of lung nodes
The causes of lung lumps include smoking or dust, infection, autoimmunity, benign lung tumors, malignant lung tumors, and so on. Smoking or dust can cause an immune inflammation reaction, forming a granuloma. Nodules can also be caused by infections such as malaria, aspergillosa, and cryptococci. Immune diseases such as rheumatism, necrotizing, and sarcoidosis can also lead to the formation of noduli. Benign tumors of the lung, such as tumors, hamartomas, and cavernous tumors, may also cause these tumors. Lung cancer, such as lung adenomas or metastasizing malignant tumors, can also cause lung nodes to appear.
Can lung nodes be cured?
The lung nodes could be cured. The treatment of lung nodes depends on the nature and cause of the nodes. Benign lung nodes can usually be treated with medication or surgery. For infected nodes, antibiotics can improve the absorption of the nodes. However, the treatment of malignant lung nodes is relatively difficult, and long-term treatment is needed to control the malignant tumor. Therefore, whether or not the lung nodes could be completely cured depended on the nature of the nodes and the individual's condition.
Is it contagious to get lung nodes?
Lungs are usually not contagious. Lung nodes did not refer to a specific disease, but the manifestation of the disease in chest imaging. Most of the lung nodes were benign diseases, such as infectious diseases, fungus infection, chronic inflammation, etc. Nodules caused by a person's infection were infectious diseases, but these were usually traces left behind by a person's infection, not an active infection. Other types of lung nodes, such as lung cancer and inflammation, are usually not contagious. Therefore, lung nodes were generally not transmitted to others.
