Age Quote by Richard Doll
“The risk of developing carcinoma of the lung increases steadily as the amount smoked increases. If the risk among non-smokers is taken as unity and the resulting ratios in the three age groups in which a large number of patients were interviewed (ages 45 to 74) are averaged, the relative risks become 6, 19, 26, 49, and 65 when the number of cigarettes smoked a day are 3, 10, 20, 35, and, say, 60-that is, the mid-points of each smoking group. In other words, on the admittedly speculative assumptions we have made, the risk seems to vary in approximately simple proportion with the amount smoked.”
About This Quote
Smoking quantity correlates linearly with lung cancer risk, showing a steep rise as daily cigarettes increase.
In simple terms: More cigarettes, higher lung cancer risk.
Key Takeaway
Risk escalates roughly proportionally to smoking dose.

Questions to Reflect On
- How does this dose‑response inform smoking cessation strategies?
- What are the limitations of assuming a linear relationship?
A Different Perspective
Other factors like genetics or environmental exposure also influence lung cancer risk, so smoking is not the sole cause.
