Asbestos-related lung cancer
A free high-yield preview for the UKMLA Applied Knowledge Test, covering how to recognise this condition. The full SA Note notes add investigations, management and complications, with practice questions on this topic.
Key high-yield points
- Asbestos causes both primary lung carcinoma (any histological subtype) and mesothelioma - distinct entities
- Latent period: 20-45 years between first exposure and diagnosis
- Crocidolite (blue) asbestos is the most dangerous fibre type - amphibole, straight, needle-like, penetrates deeply and persists indefinitely
- Pleural plaques - benign, not premalignant; confirm prior asbestos exposure but do NOT increase risk of lung cancer or mesothelioma
- Severity of asbestosis correlates with duration and intensity of exposure
- Smoking + asbestos = multiplicative synergy for lung cancer risk (smoking impairs mucociliary clearance, increasing fibre dwell time)
Pleural plaques are benign and NOT premalignant - a common exam trap. Their presence confirms asbestos exposure but does not independently raise malignancy risk.
