Nowadays, there are more and more detection of lung nodules in the pulmonary examination. Many people talk about "knot" color changes. They believe that lung nodules are pre -cancer lesions or even lung cancer, which produces anxiety and fear.

What is going on with node nodes? How to determine the follow -up time for patients with lung nodules? Let ’s take a look at the possible development of the lung nodules and correctly understand the lung nodule correctly.

The physical examination found that the lung nodule is not all removed immediately

What exactly is lung nodule? In the CT examination of the lungs, the lung nodule refers to the spare, circular, and density grinding glass, sub -real or solid lung shadow that is ≤3cm in the lung diameter, and the lesion can be single or more.

According to the diameter of the lung nodule, the nodules are divided into: tiny nodules (diameter <5mm), small lung nodules (diameter 5 ~ 10mm), and lung nodule (diameter 11 ~ 30mm).

Based on the density of the lung nodule, the lung nodules are divided into: pure grinding glass nodules (PGGN), partial solid nodules (PSN), solid nodules, and calcified nodules.

When the medical examination is found in the lung nodule, don't be anxious, let alone surgical resection as soon as possible. Be sure to clarify the nature of the lung nodules under the professional judgment of the doctor. To.

How does a doctor make accurate judgment on the lung nodules?

For each nodule, observe the occurrence, diameter, form, density of the nodules, whether there are burrs, leaves and neighbors, or whether there are drainage bronchials, vascular gathering signs and air bubbles. According to the above observation comprehensive judgment The nature of the lung nodule, then formulate the next diagnosis and treatment plan, surgical treatment or closely follow -up of patients.

We must pay attention to the early detection of lung cancer, but also avoid excessive treatment of lung nodules.

Nakaurous nodule diameter> 1cm3 ~ 6 months follow -up once every time

How to determine the follow -up time? For the first discovery of the lungs, the diameter ≤1cm lung nodule, when the probability of malignancy is high, the patient's physical condition can tolerate surgery and choose surgical resection. After symptomatic treatment, follow -up observation is performed according to the diameter.

There are no high -risk factors in the lungs, and there is no follow -up. If there are high -risk factors, it is recommended that the annual chest low -dose CT review is recommended. Low -dose CT review of the chest in the lung nodule for 3 months, half a year, and 1 year.

Diameter> 1cm nodules, biopsy, enhanced CT and other clear lesions, malignant nodules performed surgical treatment; benign nodules, can be followed up for 3 to 6 months.

During the follow -up process, all nodules have rapidly increased nodules and increased density. Divide leaves, burrs, and pleural depression occur. Considering evil changes in nodules, and positive treatment methods are taken.

For high -risk people in lung cancer, such as elderly men, smoking, and family history of tumor family, you need to carry out low -dose CT screening of the chest of the year; avoid carcinogenic factors in the environment in daily life, no smoking, stay away from second -hand smoke, to indoor and outdoor air Pollution protection.

At the same time, we must maintain a good mentality and healthy living habits, carry out proper physical exercise, and enhance the body's immunity.
