The Claim
Smoking was the leading contributor to the global cancer burden among modifiable risk factors, accounting for 15.1% of cases, followed by infections at 10.2% and alcohol consumption at 3.2%, based on population-attributable fraction estimates.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
This claim says that smoking causes more cancer worldwide than any other risk factor we can change, responsible for about 15 out of every 100 cancer cases. Infections come next at 10 cases, and alcohol at 3 cases.

What the research says
1 studyStudy: Global and regional cancer burden attributable to modifiable risk factors to inform prevention.
The study looked at the same things as the claim—smoking, infections, and alcohol—and found the exact same numbers, so it supports the claim fully.
