The key importance of vitamin D is highlighted in another study.

“Among patients with colorectal cancer, higher prediagnosis plasma 25(OH)D levels were associated with a significant improvement in overall survival.” concludes a new study published in the Journal of Clinical Oncology.

For the study, researchers analyzed data from the Nurses’ Health Study (NHS) and the Health Professionals Follow-Up Study (HPFS), two long-running epidemiologic studies whose participants gave blood samples and whose health has been monitored for many years.

Research has linked vitamin D about a 50 percent reduction in the risk of developing colon and rectal cancer. This research fuocused on the survival of cancer patients.

Researchers analyzed 300 people from the NHS and the HPFS studies diagnosed with colon cancer between 1991 and 2002. All the subjects had vitamin D levels measured in blood samples taken at least two years before being diagnosis with colon cancer.

The researchers followed the patients survival through death or until 2005.

The results showed that individuals with the highest levels of vitamin D in their blood were 39 percent less likely to die from colon cancer than folks with the lowest lowest vitamin D.

Based upon the results, further study should be done on the issue, say researchers
