Introduction
Whether multiple lung nodules smaller than 5 mm are concerning depends on the nature of the nodules and clinical symptoms. If the nodules have smooth margins, no discomfort is present, and they are diagnosed as benign, they are generally not a cause for concern; treatment may be deferred, but regular follow-up examinations are needed. However, if the nodules show spiculated margins and are accompanied by chest discomfort, and are diagnosed as malignant, they are usually serious, and without treatment, they may be life-threatening.
Multifocal lung nodules smaller than 5mm may or may not be concerning, depending on the nature of the lung nodules and associated clinical symptoms.
1. Not concerning: If imaging tests show that the nodules have a smooth surface, well-defined borders, and do not cause any discomfort or symptoms, and are confirmed to be benign, they are generally not a cause for concern. In such cases, special treatment may not be necessary, but regular follow-up visits at the hospital are recommended.
2. Concerning: If the nodules have an irregular surface or spiculated margins, and are accompanied by symptoms such as chest tightness, chest pain, or shortness of breath, there is a higher possibility of malignancy. Further diagnostic evaluations are required. If the nodules are confirmed to be malignant, they are indeed concerning, and failure to treat them promptly may endanger the patient's life.
When multiple lung nodules are detected, to prevent potential health risks, it is advisable to undergo comprehensive evaluation at a reputable hospital and receive appropriate treatment accordingly.
