Lung nodular hyperdense images, i.e. lung nodules, need to be judged according to the examination and test results to determine their benign or malignant nature. Benign nodules can be followed and observed, while malignant nodules require surgical treatment, radiotherapy, chemotherapy, and so on. Lung nodules are masses that are higher than the density of the lung tissue found in the imaging examination of the lungs. According to the examination test results, especially the pathological biopsy to determine the benign and malignant, if the nodule is benign, no special treatment is needed, but should follow the doctor’s instructions for regular follow-up. If the pathological biopsy suggests a malignant nodule, or if the nodule is highly suspected to be malignant after evaluation by a professional physician, surgery should be performed as early as possible, and radiotherapy, chemotherapy, targeted therapy, immunotherapy, etc., may be performed according to the needs of the condition after the surgery. When lung nodules are found, it is recommended to seek timely medical treatment and standardize the treatment under the guidance of professional doctors.
