In this solo episode of Keeping Abreast, Dr. Jenn Simmons takes on one of the most accepted messages in women's health and dismantles it with decades of evidence. Routine yearly mammography screening does not hold up when you actually read the trials. Dr. Jenn walks through the WISDOM trial, the Cochrane Review, the Canadian Breast Cancer Screening Study, and the brand new 2026 American College of Physicians guidelines to make the case that one-size-fits-all screening is not just outdated, it is causing real harm.
She also takes on the estrogen myth that has left millions of women suffering through hot flashes, bone loss, brain fog, and lost quality of life for decades. A 1.8 million woman study and the Women's Health Initiative say estrogen is not the villain. The real culprit may be something millions of women are still being prescribed today.
If you have ever been told to just get your mammogram every year without a single conversation about the risks or what the data actually shows, this is the episode you have been waiting for.
