Vitamin D: 77% of Cancer Patients Sub – Optimal or Deficient

A number of studies have associated vitamin D with cancer, but until recently studies

have not looked at whether vitamin D has any impact on the prognosis or development

of the disease. One recent US study sought to establish the vitamin D levels of patients

at a community Oncology practice. The study involved 160 patients with a median

age of 64 years and a 1:1 ratio of men to women. The five most common primary

 cancers were breast, prostate, lung, thyroid and colorectal cancer. 77% of patients had

either deficient vitamin D levels (lower than 20ng / mL) or sub-optimal levels

(20-30 ng / mL). Deficient patients were given replacement therapy increasing their

serum levels by an average of 14.9 ng / mL
