Hypothesis
What are the risk factors for oesophageal, lung, oral, and laryngeal cancers in black South Africans?
Conclusion
Tobacco smoking is the major risk factor for oesophageal, lung, oral, and laryngeal cancers in black South Africans.
Supporting Evidence
- Tobacco smoking was found to be the major risk factor for all cancers studied.
- Long-term residence in the Transkei region is a significant risk factor for oesophageal cancer.
- Frequent alcohol consumption increases the risk of oesophageal cancer, especially in smokers.
