A real patient story — and why I recommend patient never skip her mammogram.
A patient recently came to my office asking for an ultrasound only — she didn't want a mammogram. We did the ultrasound first. It was normal. But given her age, I explained that mammography can find things ultrasound alone will miss. She agreed to add it.
That mammogram found 5 centimeters of highly suspicious calcifications. We biopsied two separate groups and found high-grade ductal carcinoma in situ with microinvasion, HER2-positive — a fast-moving, aggressive process. Her mammogram the year before was normal. Her ultrasound this year was also completely normal. The mammogram was the only exam that caught it.
She has thanked me more than once for insisting on the data, not just her preference.
Here's the bottom line I want every woman reading this to know:
Mammography remains the only screening exam backed by randomized controlled trial data — 9 trials, over 600,000 women — showing roughly a 50% reduction in breast cancer deaths. No other imaging test (ultrasound, breast MRI, contrast-enhanced mammogram, QT ultrasound, thermography) has that level of evidence.
The radiation dose is only 0.4 millisieverts. Compression lasts about 4 seconds — often less pressure than everyday things like sleeping on your stomach or wearing a bra.
If you have dense breast tissue, add breast MRI, contrast-enhanced mammography, or ultrasound. If you're drawn to thermography or QT ultrasound, that's fine too — as an addition, per American College of Radiology guidelines, never a replacement for your annual mammogram.
Please don't let something you saw on social media talk you out of the one exam with the strongest evidence behind it. Early detection gave this patient her best chance. It can do the same for you.
Because every woman is precious. 💗
