Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Failure to lower skin cancer risk with vitamin D

    Researchers at Stanford University School of Medicine, in Redwood City, California, evaluated the effects of vitamin D combined with calcium supplementation on melanoma skin cancers.

    First, the details.

    • 36,282 postmenopausal women enrolled in the Women’s Health Initiative calcium/vitamin D study were randomly assigned to a treatment group for about 7 years.
      • 1,000 mg of elemental calcium + 400 IU of vitamin D3 daily
      • Placebo
    • Nonmelanoma and melanoma skin cancers were recorded.

    And, the results.

    • The rate of nonmelanoma and melanoma didn’t differed between treatments.
    • Women with a history of nonmelanoma skin cancer taking vitamin D + calcium had a significantly reduced risk of melanoma vs those taking placebo.
      • This was not observed in women without history of nonmelanoma skin cancer.

    The bottom line?

    The authors concluded, “Vitamin D supplementation at a relatively low dose plus calcium did not reduce the overall incidence of nonmelanoma skin cancer or melanoma.”

    But the suggestion of a potential role for calcium + vitamin D supplements in women at high risk of nonmelanoma skin cancer warrants more study.
