 Researchers at the Chinese Academy of Medical Sciences in China found a similar association between excessive vitamin D intake and esophageal and gastric cancers in men. Male subjects with levels of 25-D in the range of 48.7 ng/ml (which once again suggests heavy supplementation) were much more likely to develop one of the two forms of cancer.(({{pubmed>long:17551495}})) A 2011 case control study found that those in the highest 25% of vitamin D intake compared to those in the lowest 25% were significantly more likely to develop oesophageal adenocarcinoma.(({{pubmed>long:21736847}})) Researchers at the Chinese Academy of Medical Sciences in China found a similar association between excessive vitamin D intake and esophageal and gastric cancers in men.

 <blockquote>Abstract Vitamin D has been hypothesized to protect against cancer. We followed 16,819 participants in NHANES III from 1988 through 2006, expanding upon an earlier NHANES III study (1988-2000). Using Cox proportional hazard regression models, we examined risk related to baseline serum 25-hydroxyvitamin D (25(OH)D) for total cancer mortality, in both sexes, and by racial/ethnic groups, as well as for site-specific cancers. Because serum was collected in the south in cooler months and the north in warmer months, we examined associations by collection season (“summer/higher latitude” and “winter/lower latitude”). We identified 884 cancer deaths during 225,212 person-years. Overall cancer mortality risks were unrelated to baseline 25(OH)D status in both season/latitude groups, and in non-Hispanic whites, non-Hispanic blacks, and Mexican-Americans. In men, risks were elevated at higher levels (e.g., for ≥100 nmol/L, RR= 1.85 (95% CI=1.02-3.35) compared to <37.5 nmol/L).</blockquote> <blockquote>Abstract Vitamin D has been hypothesized to protect against cancer.
