High Vitamin D Levels May Improve Breast Cancer Survival.
A new study suggests that breast cancer patients who have higher blood levels of vitamin D are twice as likely to survive the disease compared to patients with lower blood levels of vitamin D. Researchers found that breast cancer patients in the United States have an average blood level of vitamin D of 17 ng/ml. Based on their findings, patients with breast cancer may benefit from having vitamin D blood concentrations measured and adjusted to within a normal range of 30-80 ng/ml. Study co-author Dr. Heather Hofflich adds, “The study has implications for including vitamin D as an adjuvant to conventional breast cancer therapy.”
