Can normal CT detect cancer?

Common CT can detect cancer, such as head CT can detect intracranial space occupying, such as glioma, astrocytoma, etc. The main signs are irregular edema around the tumor lesions, like crab claws, and the space occupying effect is obvious, suggesting that the possibility of tumor is large. In addition, chest CT can detect early lung cancer, and chest CT is used for early lung cancer screening at this stage. If a lump or ground-glass nodule is found on the lung, the shape of the lesion is irregular, and there are spicules, lobulation, bronchial truncation, and pleural depressions around it. It is highly suggestive of lung cancer. However, CT is only an imaging examination. If you want to confirm the type of lesion, you still need to rely on pathology. The final result still needs to rely on pathological section to judge.
