Are small lung nodules a sign of lung cancer? Not necessarily. There are many causes.

There are many reasons for the formation of pulmonary nodules. They may be benign diseases, but they are also a sign of lung cancer. Among all patients, malignant diseases occur in about 5%, and benign lesions occur in about 80% to 90%. After discovering pulmonary nodules, pay attention to further examination. Lung cancer usually occurs in people over 40 years old who smoke frequently.

Lung cancer is a relatively serious disease that can affect the patient's life. So when there are some problems with the lungs, people will worry that it is caused by lung cancer. So they will be afraid after getting sick, especially after small lung nodules appear. So are small lung nodules a sign of lung cancer?
Small lung nodules are nodules with a diameter of about 10mm found during lung CT scans. Nodules vary in size. Nodules smaller than 7mm are called micronodules, while nodules smaller than 3mm are called micronodules. Nodules generally have no symptoms, especially small nodules in the lungs, which may be distributed in various parts of the lungs. Small lung nodules are not necessarily caused by lung cancer, but lung cancer cannot be ruled out.
Many lung diseases can cause pulmonary nodules, such as inflammation, fungus, lymph, tuberculosis, bleeding, etc. Among all patients, only 5% have malignant diseases. When small nodules are found in the first lung CT, 80% to 90% of patients have benign lesions.
However, if the diameter of the nodule is too large, among the single nodules in the lung with a diameter greater than 25mm, more than half are malignant lesions, which needs attention. Therefore, if you find a small nodule in the lung, you must be careful not to take it lightly. It is generally recommended to receive further examination as soon as possible and receive timely treatment.
Lung cancer usually occurs in people over 40 who have smoked for more than 20 years. If you smoke more than 20 cigarettes a day or have chronic lung disease, you should pay attention to your waist. Also, if you have chest pain, cough, coughing up blood, or unexplained weight loss, you should pay attention.
The above is some explanation for the question of whether small lung nodules are a sign of lung cancer. Lung cancer is a very serious disease. Once discovered, you should pay attention to it in time and receive professional examinations. At the same time, you should also pay attention to quitting smoking. Most lung diseases are caused by smoking stimulation.
