What do you think are the more dangerous places for lung nodules?

A pulmonary nodule is a round or irregular mass in the lungs that is less than or equal to 3 cm in diameter. There are single or multiple nodules, solid nodules, partially solid nodules, and ground-glass density nodules. There are clear or blurred lines.

Ground-glass nodules in the lungs are ground-glass nodules that appear on CT scans. Among these nodules, some solid nodules have the highest probability of developing lung cancer, followed by ground-glass density nodules, and solid nodules have the lowest probability of developing lung cancer. In addition to chest X-rays, computed tomography and MRIs, the patient's history and signs are also reviewed.

Such as occupations, chemical plants, sterilizers, etc. History of smoking, history of chronic pulmonary disease, bacterial infection, etc.

High-risk nodules are usually 15 mm or more in diameter and 8 to 15 mm in diameter, but burrs and lobulation may occur. Moderate risk refers to people who are 5 to 15 mm in diameter and have no other high-risk characteristics. Solid nodules less than 5 mm in diameter are low-risk pulmonary nodules.

First, look at the size of your lung nodules. You should go to the hospital to prescribe some anti-inflammatory drugs, have regular check-ups, and keep in touch with your doctor. It's a great style of relaxation and recovery, especially for sedentary people.

Of course, it also includes long walks, such as shopping, traveling, hiking, etc. Lying on your back for 10 to 15 minutes in this way can immediately relieve a series of uncomfortable symptoms such as fatigue and swelling.

It should not be performed in patients with hypertension and cerebral infarction. Practice against the wall in groups, and the time against the wall should not exceed 3 minutes each time. 3.

Place a soft cushion under your head to avoid injury. 4.It is suggested that the two should alternate between protection and assistance.

When the center of gravity is on the two small arms, the force area is comparatively larger. If you put your palms on the ground, you can also use your hands to support you. Low level of difficulty.

Practicing handstand for a month can exercise the strength of the upper limb muscles, improve blood circulation, and relax tense and tired muscles. When practicing handstands, pay attention to concentration, maintain balance, and practice consistently for a while. Simple inflammatory nodules.

That is, nodules caused by inflammation, including nodules caused by bacterial, fungal infections, tuberculosis, silicosis and other infectious diseases. May be present frequently, but usually disappear after **.

Nodules are numerous in the right lung, and nodule density is not described, i.e., the nodules are solid, ground-glassy, or mixed. The number of nodules is not described. In general, 3 or more nodules are called multiple nodules.

Whether the border is clear or not, whether there is calcification, is not mentioned. The shape of the nodules is spherical and triangular and is not visible from the report; There is no way to know if the boundaries are clear. When a lung nodule is found, respiratory physicians, especially those involved in lung cancer, first assess the risk and then take appropriate measures.

For patients with a low risk of cancer, follow-up observation is often used, and the duration of follow-up observation depends on the likelihood of cancer risk for lung nodules and the presence of cancer risk factors.

The more dangerous places for pulmonary nodules are mainly in the following aspects:

Location: When the location of the pulmonary nodule is close to the trachea, bronchi or blood vessels, it may adhesion with the surrounding tissues, and it is difficult to separate during the operation, which can easily lead to massive bleeding, endangering the patient's life and high risk. In particular, when the pulmonary nodule is close to the hilum of the lungs, including pulmonary arteries, pulmonary veins, bronchi, nerves, etc., and when the pulmonary nodule enlarges, it may cause compression symptoms on the surrounding tissues or organs, and symptoms such as dyspnea, chest pain, cough, and hemoptysis may occur, and the degree of risk is also high.

Size: The size of the pulmonary nodule is also an important factor in determining its risk. Pulmonary nodules are more dangerous if they grow faster or if they are malignant.

Morphology and nature: The morphology and nature of pulmonary nodules can also reflect how dangerous they are. Pulmonary nodules with irregular morphology, undefined margins, or uneven density, or features such as lobulation and burrs may indicate malignant nodules and require further investigation.

In short, for pulmonary nodules, especially those close to the trachea, bronchi or blood vessels, as well as pulmonary nodules that grow rapidly and have abnormal morphology and nature, it is necessary to arouse a high degree of vigilance and seek medical attention in time for examination and **. At the same time, maintaining good living habits and environment, avoiding smoking and long-term exposure to harmful environments are also important measures to prevent lung nodules.

Pulmonary nodules that are close to the hilum or near the subpleural are dangerous if malignant and require an aggressive diagnosis and**. Because subpleural nodules, particularly those located in the middle lobes of the lungs, are more likely to metastasize to the intrapulmonary lymph nodes.

It should be in the location of the blood vessels, the location of the bronchi, these two locations are very dangerous, can cause some cancer, and can also lose their lives.

The main trachea and bronchi are very dangerous, because they affect our normal breathing, and there is a high probability of cancer.

If the pulmonary nodule grows away from the hilum of the lungs, it is relatively safe, and if the pulmonary nodule is benign, it is also relatively safe, and it can be completely eliminated by certain measures.

I also think it's very dangerous, because this disease is really contagious, it can also spread, it is very dangerous, and it is very easy to get some diseases.

We often detect small lung nodules during physical examinations, but lung nodules ≠ lung cancer, the vast majority of lung nodules are benign, and only a small number of dangerous lung nodules will develop into lung cancer.

Nowadays, with the increasing popularity of CT examination in health examinations, the detection rate of pulmonary nodules is also increasing. It has been reported that the proportion of small lung nodules detected on physical examination is as high as 20-30%, and the detection rate in smokers is nearly 50%.

What is a pulmonary nodule?

Pulmonary nodules are a concept in medical imaging, and those smaller than 3cm are called nodules. In layman's terms, for example, the long bag on our face, or the pimple on our body, and the nodule growing on the lungs is called a pulmonary nodule.

What should I do if a lung nodule is found during a physical examination?

First of all, don't be too nervous because of the physical examination found lung nodules, lung nodules do not equal lung cancer, most nodules are benign.

Secondly, regarding the treatment of pulmonary nodules, there are the following situations: one is a benign nodule, which should be closely observed and followed up for a long time; One is the nodule caused by inflammation, which should be anti-inflammatory** under the guidance of a doctor, and then perform chest CT examination; For an unqualified nodule, long-term chest CT follow-up should be carried out according to the doctor's instructions, and if there is a high suspicion of lung cancer, the nodule should be "vigilant and operated in time".

Even if cancer is detected very early, it can be done as long as it is done properly and in a timely manner. Therefore, it is the right choice to find a professional doctor when you get a report of pulmonary nodules, and follow the doctor's instructions.

From the perspective of traditional Chinese medicine, it is easier to get the two constitutions of lung nodules?

From the perspective of traditional Chinese medicine, qi stagnation and blood stasis, blood stasis and phlegm stasis are prone to lung nodules. According to my 40 years of clinical experience, people with the following two constitutions are more likely to get lung nodules.

First: people with yang deficiency constitution, especially those with yang deficiency in the lungs and spleen, do not dissolve fluid. The fluid turns into phlegm, and the phlegm condenses into a nodule.

Second: People with damp and hot constitution, who often have a bitter mouth, dry mouth, thick tongue coating, sticky stool and other damp and hot constitution, are also prone to damp heat stagnation in the body, affecting the flow of qi and blood to form a nodule.

What are the precautions?

Quit smoking, avoid exposure to secondhand smoke and thirdhand smoke; ventilation in the kitchen, use of range hoods when cooking, and wear masks with protective functions; Stay away from smog, establish a good lifestyle, and keep a good mood; Those over the age of 40 have regular health check-ups every year.

To improve the concept of health management, Dr. Guo Yuqin, director of the Department of Traditional Chinese Medicine and Respiratory Medicine of Beijing Sihui West District Hospital, said that having a healthy lifestyle, regular physical examination, and finding a professional doctor to solve lung nodules are the key to early detection, early diagnosis, and early diagnosis.

This disease is generally infected by viruses or bacteria, or it may be because long-term smoking occupations or some toxic substances will have a serious impact on their abdomen, resulting in the occurrence of this disease, if you want to prevent this from happening, first keep the atmosphere clean, but also keep the surrounding environment clean, let yourself breathe in a better state.

The causes of the disease are different: pulmonary sarcoidosis is an unspecified multi-system and multi-organ granulomatous disease, which often invades the lungs, bilateral hilar lymph nodes, eyes, ** and other organs, and its thoracic invasion rate is as high as 80% 90%. Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which can affect many organs, with pulmonary tuberculosis infection being the most common.

Pulmonary nodules are dangerous, and chest tightness, shortness of breath, and even cyanosis may occur when the lesions are extensive. It can be aggravated by co-infection, emphysema, bronchiectasis, cor pulmonale, etc. If sarcoidosis involves other organs at the same time, symptoms and signs may occur.

Although pulmonary nodules and tuberculosis are only one word apart, they are two very different diseases. Pulmonary nodules refer to the fact that there are some spots or nodules in the lungs found by the patient during X-ray or CT examination, which are not infectious, and if there is only one spot, it will not cause much harm to the human body, and the patient's body will not appear abnormal. Tuberculosis refers to a lung infection, which is contagious, and most of the causes are caused by patients infected with Mycobacterium tuberculosis, when patients suffer from tuberculosis, they will be accompanied by cough, night sweats, weight loss and other symptoms.

Pulmonary nodules are small, focal, round-like, and radiographically appear as dense opacities, which may be single or multiple, without atelectasis, hilar enlargement, and pleural effusion.

Solitary pulmonary nodules are usually atypical and often have a single well-defined, densely populated soft tissue less than 3 cm in diameter.

Pulmonary nodules can be divided into:

Benign nodules, such as inflammation, tuberculosis, mold, pulmonary hemorrhage, etc., among which benign ones can be inflammatory pseudotumors, hamartomas, tuberculous globules, fungal infections.

Malignant nodules, which can be primary lung cancer or metastatic cancer in the lungs, some benign lesions, may also transform into malignant after a long time.

For patients with pulmonary nodules, it is recommended to quit smoking, monitor the lungs regularly CT, and closely observe the changes in the size and morphology of the pulmonary nodules. If progression is found, patients should be referred to a specialist hospital for further diagnosis and treatment, and if necessary, direct tracheoscopic biopsy is performed.

A pulmonary nodule is a round or oval image of the lungs that appears less than 3 centimeters. Usually, it is found incidentally on an X-ray or CT scan, and most people with pulmonary nodules do not have symptoms.

1.Cough or bloody sputum.

2.Shortness of breath or wheezing.

3.Chest pain or back pain.

4.Fatigue or weight loss.

It is important to note that lung nodules do not necessarily represent lung cancer. In fact, about 95% of lung nodules are benign (non-cancerous). The main causes of these non-cancerous lung nodules include lung infection, tuberculosis, lung inflammation, lymphoid tissue proliferation in the lungs, etc.

However, about 5% of lung nodules are malignant, meaning they are lung cancers. Therefore, for people with pulmonary nodules, further examination and evaluation should be carried out in time to determine whether it is a malignant tumor and to bend as appropriate.

In short, if you find that you have lung nodules, please consult a medical professional in time and receive the examination and treatment recommended by the doctor. This will help identify potential health problems early and protect your physical health.

Many people find that they have been detected with a lung nodule during a physical examination, what exactly is this lung nodule? Will it be cancerous?

With the widespread application of AI-assisted thin-slice low-dose spiral CT in lung physical examination, the detection rate of pulmonary nodules is also increasing year by year. However, please rest assured that more than 90% of nodules detected are benign, which means that the detection of pulmonary nodules does not mean that they have an incurable disease.

Pulmonary nodules refer to round or irregular lesions with a diameter of less than or equal to 3 cm in the lungs, and the main causes of pulmonary nodules include many reasons, such as smoking, air pollution, bacterial and fungal infections, tuberculosis globules, sclerosing hemangiomas, etc.

In general, the nodule should be judged by its size, shape, and density.

If the physical examination is a small nodule of 2 4 mm, there is generally no need to worry too much;

4 Lung nodules between 7 mm have only a 1% chance of becoming cancerous;

If the diameter of the nodule is 8 mm 2 cm, the probability of malignancy is about 15%.

If the diameter is more than 2 cm, about 75% of it is lung cancer.

In addition to the diameter, it is also necessary to look at the density and margin of the pulmonary nodules, the edges are smooth and sharp for benign lesions, and the boundaries are unclear, irregularly contoured, lobulated, burr edges and other malignant nodules.

According to the internationally recognized guidelines for the follow-up of pulmonary nodules, solid nodules below 6 mm do not care, 6 8 mm CT is done every six months, if it cannot change in two years, it is not a big deal; CT is done every 3 months for those above 8 mm.

The follow-up of subsolid nodules should be done more frequently, and nodules below 6 mm should be followed up once every six months; Nodules over 6 mm should be followed up semi-annually for at least five years. For some solid nodules, it is recommended to check once every 3 months.
