Reply #153: and then there's this: Lack Of Sunlight May Increase Lung Cancer Risk

[Hannah Bell]

but oops, these "international databases" show smoking's only responsible for 75-85% of lung cancers. I guess they must be using different *statistics*, eh?


Lack of sunlight may increase the risk of lung cancer, suggests a study of rates of the disease in over 100 countries.

International databases, including those of the World Health Organization, and national health statistics were used.

Smoking was most strongly associated with lung cancer rates, accounting for between 75% and 85% of the cases.

But exposure to sunlight, especially UVB light, the principal source of vitamin D for the body, also seemed to have an impact, the findings showed.

Fact is, they don't know. The methodology is to take a sample of cases, find out what % smoked, & then *assume* the smoking *caused* the cancer, & publish this as though it were some definitive finding.

But it's not.
