8mm lung nodules are not necessarily nothing to worry about. Lung nodules do not rely solely on the size of the nodule to determine the severity of the disease, but also need to be judged based on a variety of factors. 8mm lung nodules should be judged comprehensively, which is conducive to the treatment as well as improvement of the disease, and the prognosis is usually better. For the relatively small size of the nodule, there is usually no obvious discomfort symptoms, if the patient has obvious cough, cough sputum, chest tightness, shortness of breath and other uncomfortable symptoms, we should promptly go to the hospital for examination and take appropriate treatment. Patients with lung nodules should avoid smoking and alcohol in their daily life, and avoid spicy and stimulating food in their diet to avoid aggravating their condition.
