Vitamin D and Colorectal Cancer

Those with higher vitamin D levels appear less likely to develop colorectal cancer in the first place;but if they do,they seem less likely to die from it,a recent study published in the Journal of Clinical Oncology found.The study set out to explore the influence of vitamin D on the outcome of patients with established colorectal cancer.It found that higher vitamin D levels were associated with a significant reduction in overall mortality,and a trend toward improved colorectal cancer mortality was also observed.
The study concluded that,among colorectal cancer patients,higher prediagnosis vitamin D levels were associated with a significant improvement in overall survival.Further study of the vitamin D pathway and its influence on colorectal cancer origins and progression is warranted,the authors felt.Corresponding author was Kimmie Ng,MD,MPH,of the Dana-Farber Cancer Institute in Boston.
Colorectal cancer is diagnosed in 112,000 Americans every year.Its incidence has also been associated with red meat and processed meat consumption.
