Bronchogenic carcinoma, commonly known as lung cancer, is the most common type of cancer worldwide. This malignant disease typically begins in the cells lining the bronchi or air passages in the lungs. There are several different types of bronchogenic carcinoma, including small cell lung cancer, non-small cell lung cancer, and mesothelioma. Synonyms for bronchogenic carcinoma include pulmonary carcinoma, lung neoplasm, lung tumor, and pulmonary malignancy. These terms are often used interchangeably to describe lung cancer and its various subtypes. Bronchogenic carcinoma can be caused by several risk factors, including smoking, exposure to carcinogens, and genetics. Early detection and treatment are critical for improving survival rates and outcomes for individuals with lung cancer.
