While at the outpatient clinic, I met Mr. Lee. He held a CT report and asked me nervously, "Doctor, my lung nodule has blood vessels running through, is it dangerous?"Surgery must be performed quickly so that it does not spread to the whole body through blood vessels!Mr. Li's question is very common, and many people are very worried when they see the words "blood vessels penetrating".
What does it really mean for a pulmonary nodule to have blood vessels running through it?
Pulmonary nodules are small, round or oval lesions that appear in the lungs, usually less than 3 cm in diameter. Most lung nodules are benign, but it is also possible to be malignant, i.e., lung cancer. On the other hand, "vascular penetration" means that blood vessels can be seen passing through the pulmonary nodule during imaging tests such as CT or MRI.
First, it is important to be clear that vascular penetration does not necessarily mean that a pulmonary nodule is malignant. In benign pulmonary nodules, blood vessel penetration can also be seen. For example, in benign lesions such as granulomatous nodules or hamartomas, vascular permeation is a relatively common phenomenon. Therefore, the benign or malignant nature of pulmonary nodules cannot be judged solely by the sign of vascular penetration.
Secondly, vascular perforation is not the only criterion for judging benign and malignant pulmonary nodules. When diagnosing pulmonary nodules, doctors need to make a comprehensive judgment based on multiple factors such as the patient's clinical manifestations, size, shape, and density of the nodules.
For example, if a pulmonary nodule has a regular morphology, well-defined edges, uniform density, and the patient does not have symptoms such as cough or hemoptysis, it is likely to be a benign nodule.
Conversely, if the lung nodule is irregular in shape, indistinct at the edges, uneven in density, and the patient has symptoms such as cough and hemoptysis, then further tests are needed to rule out the possibility of lung cancer.
Pulmonary nodules have "blood vessels through", meaning that the tumor will metastasize with the blood
First of all, vascular perforation is only a sign and cannot determine the nature of the pulmonary nodule, which can also be seen in benign pulmonary nodules.
Secondly, there is no clinical evidence that vascular penetrating nodules can metastasize, and there are only a few cases of ground-glass nodules with distant metastasis, but this is also due to the high density of patients, and it is not clear that vascular penetration.
In conclusion, vascular perforation is not the only criterion for judging benign and malignant pulmonary nodules. When a pulmonary nodule is found, the patient should remain calm, seek medical attention promptly, and undergo relevant tests to confirm the diagnosis. At the same time, patients should also pay attention to maintaining good lifestyle Xi and mentality to reduce the risk of lung cancer.
