The Risk Nobody Mentions After You Ring the Bell
Why Your Oncologist Might Be Missing the Biggest Threat to Your Long-Term Health.
My medical team was focused on one thing: keeping me alive and preventing advanced cancer. I’m grateful for that. But in spite of surgical menopause at 38, nobody talked about a cardiac surveillance plan. Nobody mentioned that the estrogen I’d lost to surgical menopause could be quietly affecting my blood vessels, my cholesterol metabolism, and my entire cardiovascular future.
I found out almost 20 years later. Not from a cardiologist. Not from my oncologist. From a new gynecologist who specialized in survivorship care (see The Cancer Survivorship Gap: What Doctors Don’t Know About Life After Cancer with Dr. Mindy Goldman), who wanted to know whether my heart could handle HRT. The calcium score came back, and there were the calcifications. In someone who lifts weights three days a week, does cardio the other days, eats well, and has zero family history of early-onset heart disease.

The leading killer of cancer survivors is heart disease. A 2024 meta-analysis found that cancer survivors are approximately 55% more likely to die from cardiovascular disease than the general population.
Dr. Anju Nohria directs the Cardio-Oncology Program at Dana-Farber Brigham Cancer Center. She works at the intersection that barely exists in most hospitals: where cancer treatment meets long-term cardiac risk. In this episode, she was explicit: heart damage from cancer treatment is usually silent. No symptoms. No warning signs. By the time you feel shortness of breath or chest tightness, you’ve already missed the best window to intervene.
Two things from this conversation you can act on right now:
Know your treatment’s cardiac profile. Not every cancer drug damages the heart, but anthracyclines, Herceptin, and chest radiation all carry specific cardiac risks. Ask your oncologist: what are the long-term cardiac side effects of my treatment, and what screening should I be getting? The answer depends entirely on what you were treated with.
Check your blood pressure. Dr. Nohria was unequivocal: blood pressure is the single most important cardiac number to track. Under 130/80 is the target. If yours is elevated, monitor it daily for a week and bring that log to your doctor. It’s the one metric with the most impact on long-term heart outcomes.
My blood pressure was and is great…But I had other cardiac blood markers, and it’s easy to get comprehensive blood work and a CT calcium score if you want to be more aggressive in your cardiac health monitoring.
This week’s episode gives you the specific questions to bring to your next appointment and the information to understand the answers. For paid subscribers, I’m going deeper into the research on silent cardiotoxicity and the cardiac risk that comes with long-term estrogen deprivation after cancer treatment.
