Vitamin D Toxicity Rare in People Who Take Supplements, Mayo Clinic Researchers Report



Over the past decade, numerous studies have shown that many Americans have low vitamin D levels and as a result, vitamin D supplement use has climbed in recent years. Vitamin D has been shown to boost bone health and it may play a role in preventing diabetes, cancer, cardiovascular disease and other illnesses. In light of the increased use of vitamin D supplements, Mayo Clinic researchers set out to learn more about the health of those with high vitamin D levels. They found that toxic levels are actually rare.
Their study appears in the May issue of Mayo Clinic Proceedings. For more information, see the Mayo Clinic News Network: http://newsnetwork.mayoclinic.org/

Immunotherapy and Triple Negative Breast Cancer – Mayo Clinic

A promising new study from Mayo Clinic, in conjunction with Caris Life Sciences, points to immunotherapy as a possible treatment option for patients with the difficult-to-treat triple negative breast cancer mutation. The study was presented this week at the 50th annual meeting of the American Society of Clinical Oncology in Chicago.

“This study may change our ability to treat triple negative breast cancer patients,” says Barbara Pockaj, M.D., lead investigator of the study and Mayo Clinic surgeon. “We may have signs that these patients can be treated with immunotherapy. We don’t have a lot of options for these patients and this would really expand our options.”
