Is a high-density shadow on lung CT scan a precursor to lung cancer?
A high-density shadow in the lungs detected by CT scan may be a precursor to cancer, but it might not indicate cancer if caused by other conditions or inflammation. The actual situation varies from person to person. Specific analyses are as follows:
1. It may be a precursor to cancer
A high-density lung shadow is a radiological description. If the shadow appears as an irregular mass with spiculated or lobulated margins, the likelihood of cancer is higher. It is recommended to visit a hospital for further evaluation. If cancer is confirmed, treatments such as surgery, chemotherapy, or radiotherapy can be performed under medical supervision.
2. It may not be a precursor to cancer
If the high-density shadow appears patchy, it may result from tuberculosis or pneumonia, such as pulmonary tuberculosis or granuloma. With systematic anti-inflammatory or anti-tuberculosis treatment, the shadow typically resolves gradually. If a CT scan only reveals a high-density shadow without other specific abnormalities, it is mostly indicative of benign disease.
Many lung diseases are related to genetic factors or unhealthy lifestyle habits. It is advisable to pay attention to lung health in daily life and avoid smoking.
