The CT images of lung cancer have typical features, including massive masses, irregular circles and unclear boundaries. It may also be accompanied by lobulation sign, burr sign, pleural indentation sign, vacuole sign, bronchiole inflation sign, cavity sign and vascular aggregation sign. When similar descriptions appear in CT reports, it is necessary to highly doubt the possibility of lung cancer and make further diagnosis and treatment in time.

However, there are relatively few cases of lung cancer found in the early stage, especially the small nodules below 1cm. For small nodules found in physical examination, if the edge is clear and it is a solid nodule, generally do not worry too much. However, if it is ground glass nodules or some solid nodules, it is recommended to go to a specialist for further examination and treatment in time.

According to the CT images of lung cancer, doctors can make comprehensive diagnosis and treatment by combining other examination methods and treatment schemes. For different types of lung cancer, the treatment methods are different, including surgery, radiotherapy, chemotherapy, targeted therapy and so on. Therefore, timely and accurate diagnosis is of great significance for the treatment and prognosis of lung cancer.
