Introduction

Ground-glass opacities in the lungs may gradually increase in size, and the presence of other discomfort symptoms could indicate cancer; otherwise, it may not be cancer. If repeated examinations reveal a progressive enlargement of lung ground-glass opacities accompanied by granulomas, cancer might be suspected. During treatment, patients should maintain a light diet and avoid spicy or irritating foods such as chili peppers, alcohol, and strong tea.

In general, ground-glass opacities in the lungs may gradually increase in size or be accompanied by other uncomfortable symptoms, which could indicate cancer; otherwise, they may not be cancerous. The specific details are as follows:

1. Yes (indicative of cancer)

If repeated examinations show that the ground-glass opacity in the lung is progressively increasing in size and is accompanied by granulomas, this may suggest the presence of cancer. A biopsy via needle aspiration is required to determine the precise pathological nature. Only through a comprehensive evaluation combining imaging studies, clinical manifestations, and imaging tests can a definitive diagnosis of cancer be made. As the disease progresses, symptoms such as persistent cough, shortness of breath, and chest or back pain may appear. Patients should seek medical care at a hospital where treatments such as surgery, chemotherapy, and radiotherapy may be provided.

2. No (not cancerous)

Typically, ground-glass opacities in the lungs alone cannot confirm cancer. These opacities may result from inflammation, edema, fibrosis, or other non-cancerous causes. Symptoms such as cough, shortness of breath, loss of appetite, fever, and restlessness may occur. In such cases, patients are advised to promptly visit a hospital for examination to identify the underlying cause and receive targeted treatment.

During treatment, patients should maintain a light diet and avoid spicy or irritating foods such as chili peppers, alcohol, and strong tea.

What does "ground-glass opacity in the lungs" mean, and is it serious?

Ground-glass opacity (GGO) in the lung is a radiological finding characterized by hazy, cloud-like areas of increased density in the lung parenchyma on chest CT scans; these opacities may be solitary or multiple. When GGOs are detected, their clinical significance and severity should be comprehensively evaluated by integrating various factors, including the patient's blood parameters, inflammatory markers (such as C-reactive protein and procalcitonin), tumor markers, sputum culture results, and clinical manifestations.

What is ground-glass opacity, and is it a serious condition?

Ground-glass opacity usually refers to ground-glass density shadows in the lung, which may be caused by conditions such as pneumonia, pulmonary tuberculosis, pulmonary edema, pulmonary fibrosis, or lung cancer. The severity depends on the specific circumstances. It may result from prolonged exposure to dust, with particles entering the lungs via the respiratory tract, causing pulmonary irritation and damage. It may also present as increased coarseness and disorganization of lung markings.
