What are the differential diagnoses between lung abscess and lung cancer

The differential diagnosis methods for lung abscess and lung cancer include physical examination, chest CT examination, pathological tissue biopsy, etc.

1. Physical examination: If you want to determine whether lung abscess or lung cancer occurs, you can undergo a physical examination. Patients with lung abscess usually experience symptoms such as chills, high fever, and lack of energy, while patients with lung cancer may experience symptoms such as coughing, sputum, coughing up blood, and difficulty breathing.

2. Chest CT examination: It can also be used for differentiation. When a lung abscess is examined by chest CT, a cavity may appear, but the inner wall is smooth and there may be inflammatory secretions exuding around it. When a lung cancer patient is examined by chest CT, the boundaries are unclear and there are shadows of masses or nodules.

3. Pathological tissue biopsy: In addition to this, you can also choose to perform a pathological tissue biopsy. The examination can be used to determine the malignant lesions. Generally, the pathological tissue biopsy of lung abscess is negative, while the pathological tissue biopsy of lung cancer is positive.

When diseases such as lung abscess or lung cancer occur clinically, you need to seek medical attention in time for appropriate examinations to make a clear diagnosis and then give appropriate treatment measures based on the doctor's advice.
