Vitamin D plays a significant role in our health, including cancer incidence and mortality.
Vitamin D receptor (VDR) single-nucleotide polymorphisms (SNPs) may affect its activity …

The association between vitamin D and cancer has long been studied, but the results have
been variable. Thus, there does not seem to be a consensus on whether vitamin D has a …

Higher serum 25-hydroxy vitamin D [25 (OH) D] levels are associated with decreased
colorectal cancer (CRC) incidence. In this retrospective study of Stage IV CRC patients, we …

Abstract Serum 25‐hydroxyvitamin D (25 (OH) D) has been demonstrated to be associated
with risk of colorectal cancer (CRC). However, it remains unclear whether this association …

Numerous studies have suggested that there was a significantly positive association
