Since the discovery of the DNA double helix in 1953, we have been told that gene tests for diagnosis and early detection of cancer were “just around the corner.” But the results of a major study in England testing that hypothesis using the Galleri Multi-Cancer Early Detection (MCED) test just failed miserably. 

In this study 142,000 healthy individuals age 50-77 conducted across the United Kingdom, patients underwent a Galleri blood test every year for 3 years. The intent was to detect early-stage (Stage I and II) cancer and provide earlier intervention before the cancers had spread.

The Midlife Women's Health Summit is three days on what the research actually says about menopause care when you add a longevity lens. What works, what doesn't, what's being oversold, and what to tell the patient sitting in front of you. Co-chaired by Lisa Larkin, MD, FACP, MSCP, IF, Jen Gunter, MD, FRCS(C), FACOG, DABPM, ABPMR, and Lauren Streicher, MD, FACOG, MSCP; three of the clearest voices in women's health on separating data from marketing.

Before Gerson: The Forgotten Medical History of Coffee Enemas

By Scott Wilson – In 1875, Dr. J.P. Thomas wrote about using coffee enemas for opium and belladonna poisoning. He referred to cases going back to 1858 and 1859 and described coffee enemas as one of the ordinary means of treatment. That word “ordinary” stopped me. He wasn’t describing an experiment. He was describing something physicians already knew.
