The lung puncture needle biopsy did not find tumor cells but only necrotic tissue. What's the matter?

Lung cancer cannot be ruled out. It may be that the tissue sample of the wound puncture just did not puncture the cancer cell; it may also be a pathological section. The selected tissue does not include cancer cells. You can suggest that the pathology department perform pathological examination on all the tissues submitted for inspection. It is not found, and it is not recommended to puncture the tissue again for pathological biopsy; it can be seen that other inspection methods can be selected to clarify the nature of the tumor, such as thoracoscopy, bronchoscopy, and PET-CT. It may be a benign mass, such as tuberculosis, but the necrotic tissue of tuberculosis is caseous and characteristic, but the possibility of being benign is small.
