In this episode of Keeping Abreast, Dr. Jenn Simmons sits down with Ivy Harris, a homeschool mom of four, researcher, and soon-to-be certified homeopath behind the blog Done with Diligence, for part one of a two-part conversation on the hidden risks of mammograms and breast cancer screening. Ivy is not a doctor. She's a mom who decided she wasn't going to walk into her first mammogram without doing her own homework first, and what she found is the reason this episode exists.It started with one post, Ivy broke down what she'd learned about mammograms into five parts, shared it, and watched it split her audience in half, with some women thanking her and others telling her she was going to get people killed. Dr. Jenn picks up exactly where Ivy left off and does the math no one does at check-in: 40 million screening mammograms a year, and by the numbers in the study Ivy found, the radiation alone works out to tens of thousands of cancers and over a thousand deaths a year. This is the episode you'll want to send to every woman who's ever been told a mammogram is simply safe, simply necessary, and not worth questioning.What You'll LearnThe naming decision behind "mammogram" that Dr. Jenn says was never an accidentIonizing radiation is a classified carcinogen, and why radiologists won't apply that logic to their own testThe cross-country flight radiation comparison doctors use to reassure you, and why it doesn't hold upHow breast density and size can mean 10x more radiation for one woman than another in the same mammogramWhy younger breast tissue takes more damage from radiation as screening age keeps getting pushed lowerOverdiagnosis: the NIH's own number is as high as 1 in 2 women screenedWhy DCIS, diagnosed in 90,000 women a year, has no physical route to become life-threatening breast cancerHow standard DCIS treatment can raise heart failure and fracture risk higher than the diagnosis itselfFalse positives and the 80% benign biopsy rate hiding behind every mammogram callbackWhat a 2026 American College of Physicians paper found on mammograms and breast cancer mortality, at every ageWhy decades of mammography have increased mastectomies by 20%, the opposite of what screening promisedLead time bias: how a screening test can look life-saving on paper without changing when anyone actually diesThe UK surgeon forced to resign for telling women the truth about mammogram screeningEpisode Timeline:00:00 Introducing Ivy Harris and Done with Diligence02:27 Why Ivy researched mammogram safety before her first screening03:00 Going past the rumors to the actual breast cancer research04:13 Her viral mammogram post and the backlash that followed05:32 Standing firm on breast cancer screening controversy07:39 Radiation risks: why a mammogram is a breast x-ray09:12 The studies linking mammogram radiation to breast cancer11:14 How radiation damages younger breast tissue13:36 The math: 40 million mammograms and radiation-induced cancer deaths17:59 Overdiagnosis and unnecessary breast cancer treatment26:14 The train analogy for mammogram overdiagnosis28:12 How breast cancer actually progresses versus the screening myth32:29 The real harm of overdiagnosis and overtreatment34:54 Why mammograms don't reduce all-cause breast cancer mortality50:15 Lead time bias and misleading screening survival statistics52:04 Michael Baum, saving breasts, and a Part 2 previewResources Mentioned:American College of Physicians, Annals of Internal Medicine, April 2026: https://www.acpjournals.org/doi/10.7326/M22-3424Guest: Ivy HarrisWhere to find her: Done with Diligence & @donewithdiligenceTo talk to a member of Dr. Jenn's team and learn more about working privately with Dr. Jenn visit: https://calendly.com/stephanie-1031/clarity-callTo get your copy of Dr. Jenn's book, The Smart Woman's Guide to Breast Cancer, visit: https://tinyurl.com/SmartWomansBreastCancerGuideTo purchase the auria breast cancer screening test go here https://auria.care/ and use the code DRJENN20 for 20% Off.Connect with Dr. Jenn:Website: https://www.jennsimmonsmd.com/Facebook: https://www.facebook.com/DrJennSimmonsInstagram: https://www.instagram.com/drjennsimmons/YouTube: https://www.youtube.com/@dr.jennsimmons
