Most studies have found that more Vitamin D is associated with less lung cancer
Lung Cancer Meta-analyses
- Lung Cancer more likely if poor Vitamin D Receptor – meta-analysis June 2019
- Lung Cancer risk decreased 2.4 percent with every 100 IU Vitamin D extra intake – meta-analysis Sept 2018
- Lung Cancer patients were 2.4 times more likely to have a poor Vitamin D Receptor gene – July 2017
- Lung Cancer death 60 percent less likely if high level of vitamin D – 2 meta-analysis 2017
- Lung Cancer risk decreases 5 percent for every 2.5 nanogram increase in Vitamin D – meta-analysis Sept 2015
- Lung Cancer less likely if vitamin D (higher level or supplement) – meta-analysis May 2015
Wonder if some of their prospective studies had higher levels of vitamin A
Pages listed in BOTH the categories Lung Cancer and Vitamin A
- Lung cancer 24 percent less likely if high vitamin D (never-smoking senior women) – Sept 2017
- Lung Cancer reduced by combination of Vitamins D and A – March 2014
- Less Lung Cancer if take more than 800 IU of vitamin D and never smoke or low vitamin A – Oct 2013
- Vitamin A may hinder vitamin D benefits associated with Lung Cancer – July 2013
- Vitamin D protects against lung cancer unless there is excess vitamin A – July 2012

There is observational evidence suggesting that high vitamin D concentrations may protect against lung cancer. To investigate this hypothesis in detail, we measured circulating vitamin D concentrations in pre-diagnostic blood from 20 cohorts participating in the Lung Cancer Cohort Consortium (LC3).
PATIENTS AND METHODS:
The study included 5,313 lung cancer cases and 5,313 controls selected from. Blood samples for the cases were collected, on average, 5 years prior to lung cancer diagnosis. Controls were individually matched to the cases by cohort, sex, age, race/ethnicity, date of blood collection, and smoking status in 5 categories. Liquid chromatography coupled with tandem mass spectrometry was used to separately analyze 25-hydroxyvitamin D2 (25(OH)D2) and 25-hydroxyvitamin D3 (25(OH)D3) and their concentrations were combined to give an overall measure of 25(OH)D. We used conditional logistic regression to calculate odds ratios (OR) and 95% confidence intervals (CI) for 25(OH)D as both a continuous and categorical variable.
Overall, no apparent association between 25(OH)D and risk of lung cancer was observed (multivariable adjusted OR for a doubling in concentration: 0.98, 95% confidence interval: 0.91, 1.06). Similarly, we found no clear evidence of interaction by cohort, sex, age, smoking status, or histology.
This study did not support an association between vitamin D concentrations and lung cancer risk.
