What are the risk factors for laryngeal cancer?

Reviewed: 8 November 2026 By: Xiangpeng Liu, MD Topic: Laryngeal Cancer Answer length: short, citable
Quick answer

The main recognised risk factors for laryngeal cancer are cigarette, cigar, pipe or bidi smoking — the dominant and most preventable cause, heavy alcohol use, which acts synergistically with tobacco and combined tobacco and alcohol exposure (the highest cumulative risk). Risks differ by region: Caribbean & Cuba has a distinctive exposure pattern, so a patient's country of residence is part of the risk assessment. Having a risk factor does not mean a person will develop cancer.

In detail

Risk factors are probabilistic. Many patients have no obvious exposure, and most people with an exposure never develop a head and neck tumour. Tell your clinician about all tobacco, areca nut, alcohol, occupational and viral exposures, because this information changes follow-up planning.

  • Cigarette, cigar, pipe or bidi smoking — the dominant and most preventable cause
  • Heavy alcohol use, which acts synergistically with tobacco
  • Combined tobacco and alcohol exposure (the highest cumulative risk)
  • Occupational exposures: asbestos, sulfuric acid mist, diesel fumes, coal dust and machining fluids
  • Gastro-oesophageal reflux disease and diets low in fruit and vegetables (weaker associations)
  • Male sex and older age; most cases are diagnosed in the 60–70 age group
