Lung nodules growing in the posterior basal segment of the lower lobe of the left lung depend specifically on the shape, size, and number of nodules to determine whether they are dangerous.
The severity of lung nodules has little to do with the location, most of the lung nodules are benign, the probability of malignancy is elevated for lung nodules larger than 2 centimeters, usually at 50%.
If the lung nodules have clear boundaries and regular morphology, they are generally benign, if they are ill-defined and ground glass, the probability of malignancy increases.
If the number of lung nodules is large, without calcification, the probability of malignancy is higher.
Lung nodules can also be characterized by enhanced CT or puncture biopsy.
Therefore, whether a lung nodule growing in the posterior basal segment of the lower lobe of the left lung is dangerous or not needs to be decided by the doctor’s comprehensive evaluation.
