What causes pulmonary nodules and what are the dangers?

Pulmonary nodules are generally caused by improper diet, air pollution, long-term smoking, or infection with certain fungi; Lung nodules are very harmful, they can affect our respiratory tract, destroy lung cells in the body, cause breathing difficulties, and even failure, and can also lead to pulmonary fibrosis and even cancer.

It may be caused by regular smoking, second-hand smoke, fungal infection, or fungal infection. It will directly affect a person's lungs and breathing, and will feel difficult to breathe, sometimes it will feel particularly uncomfortable, and there will also be hypoxemia, and respiratory failure will occur.

The basic pathogenesis is the onset of phlegm stasis and obstruction of the lungs, which should be paid attention to the elimination of phlegm and the dispersion of stasis, which may cause infection, damage to physical health, cause lung discomfort, affect sleep, affect life, and affect appetite.

It is caused by regular smoking, which makes your body uncomfortable, affects your breathing, affects your lung function, and your physical strength will be very weak.

People who smoke regularly are prone to damage to their lungs, long-term inhalation of dust and foreign bodies, and their lungs are also more susceptible to damage, people who have had traumatic injuries to the chest, and patients with benign tumors in the lungs.

Extended Materials. In the early stage, the pulmonary nodule has no special symptoms and is just a simple nodule, but when these symptoms such as cough, shortness of breath, and coughing up blood appear in the later stage, it means that the condition has worsened, and the patient needs to consult a regular doctor for medical treatment.

So, what exactly causes pulmonary nodules, in fact, there are many causes of pulmonary nodules, the most important ones are tumors and inflammation. The most common in inflammation are specific infections of tuberculosis tumors and fungal balls. Other common infections, including inflammation of the lungs, inflammatory granulomas or scars left after healing by ** or autoimmune resistance.

Because of infection or damage to the lungs, some lymph nodes may also grow in the lungs or under the pleura, which is also a major cause of lung nodules.

Tumors that manifest as pulmonary nodules, both benign and malignant. Benign lung tumors, the most common are pulmonary hamartoma, pulmonary hemangioma, pulmonary fibroma, etc. And malignant lung tumors, the most important is lung cancer, as well as lung sarcoma and so on.

In addition, since the lungs are the organs that are most likely to metastasize from systemic tumors, malignant tumors in other parts of the body will also appear as pulmonary nodules in the lungs when metastasis.

Cigarettes contain a large number of particle-like harmful substances, which enter the lungs through the trachea, attach to the alveoli or the lung interstitium, and some charcoal deposition forms nodules, and the pollutants in the air are the same, if there are too many, they will also cause pulmonary nodules.

Pulmonary nodules are divided into benign and malignant, do not be too nervous when detecting pulmonary nodules, and first diagnose whether they are malignant, malignant pulmonary nodules are early manifestations of lung cancer, so if they are diagnosed as malignant pulmonary nodules, they must go to a regular hospital to cooperate with the doctor** to prevent lung cancer from becoming serious and causing more serious consequences.

Benign lung nodules don't need to be too worried, generally speaking, they will not cause harm to the body, but don't be too casual, try to smoke as little as possible, keep the indoor air fresh, and let the lungs breathe fresh air.

In short, for the sake of your own health, you must pay attention to your body in daily life, do not smoke, and pay attention to staying away from dust, it is best to wear a mask when working in a special environment, when the examination finds that there are pulmonary nodules, you don't need to panic too much, cooperate with Dr. Han's examination and **, you can get rid of the trouble of pulmonary nodules as soon as possible.

Bacterial and viral infections cause pulmonary nodules.

First, the basic**.

1.Malignant primary lung cancer: mainly lung adenocarcinoma, lung squamous cell carcinoma, lung large cell carcinoma, lung small cell carcinoma. Metastatic malignant tumors: such as head and neck malignant tumors, melanoma, colon cancer, etc.

2.Benign lesions and benign tumors: such as lung hamartoma, pulmonary fibroma, pulmonary lipoma, etc.

Infection: Mycobacterium tuberculosis infection, pulmonary fungal (such as Candida, Aspergillus, Mucormycetes) infection, etc. Inflammatory lesions:

Such as granulomatous disease, sarcoidosis, etc. Pulmonary vascular abnormalities: such as pulmonary arteriovenous malformations, pulmonary telangiectasia, etc.

Congenital diseases of the lungs: such as bronchial cysts, pulmonary sequestration, etc.

2. High-risk factors.

1.Smokers or have a history of smoking.

2.Presence of fungal or bacterial infection of the lungs.

3.Previous malignancy or family history of lung cancer.

4.History of environmental or high-risk occupational exposures, such as frequent exposure to asbestos, beryllium, uranium, radon, etc.

5.Combined with chronic obstructive pulmonary disease and diffuse pulmonary fibrosis.

Extended information] 1. Pulmonary nodules: It is a common clinical sign, which refers to the circular or irregularly shaped lesions with a diameter of less than or equal to 3cm (i.e., 30mm) in the lungs, which are manifested as shadows with increased density on imaging, which can be single or multiple, with clear or unclear borders. It is usually discovered incidentally during physical examination or diagnosis and treatment of other diseases, and most patients have no obvious symptoms, and those with symptoms mostly present with symptoms such as dyspnea, chest pain, cough, and hemoptysis.

There are many types of lung nodules, which can be divided into benign pulmonary nodules and malignant pulmonary nodules according to the benign and malignant nodules of the nodules. Among malignant lung nodules, the majority are primary lung cancers, with adenocarcinoma being the most common, followed by squamous cell carcinoma. There are many causes of benign nodules, which can be caused by benign tumors, infections, inflammatory, vascular or congenital lesions.

2. Infectious: Pulmonary nodules caused by certain infectious factors (such as Mycobacterium tuberculosis infection) are infectious.

3. Incidence: Screening studies of asymptomatic people at high risk of lung cancer found that the incidence of pulmonary nodules in North America, Europe and East Asia was % and %, respectively

Fourth, the crowd that is prone to disease.

1.High-risk occupational exposures, such as workers in chemical plants, dust factories, disinfection workers.

2.Those with a history of fungal or bacterial infection of the lungs and related medical conditions.

3.Those who smoke or have a history of smoking.
