C34.02
Malignant neoplasm of left main bronchus
Clinical Classification Guidelines
Medical Intelligence & Overview
Malignant neoplasm of the left main bronchus, coded as C34.02 in the ICD-10 system, refers to a cancerous tumor that originates in the left main bronchus — one of the major airways in the lungs. This condition is a serious form of lung cancer that requires careful diagnosis and treatment. The bronchus plays a vital role in conducting air to and from the lungs, and when compromised by a malignant growth, it can significantly affect breathing and overall health.

Diagnostic & Treatment
Diagnosis Path: Medical history review and physical examination Imaging tests such as chest X-ray, CT scan, or PET scan to locate and assess tumors Bronchoscopy, allowing direct visualization and biopsy of the tumor Tissue biopsy to confirm malignancy and determine cancer type Laboratory tests including blood work and molecular testing to guide treatment options
Treatment Protocols: Surgery to remove tumor tissue, possibly including part of the bronchus or lung Radiation therapy to destroy cancer cells and reduce tumor size Chemotherapy to target cancer cells systemically Targeted therapy or immunotherapy for specific types of lung cancer Palliative care to manage symptoms and improve quality of life when curative treatment is not feasible
