In plain terms

What this procedure is, without the jargon.

This is our breast-specific version of freezing plus immunotherapy. In October 2025 cryoablation (the ProSense device) was cleared as a surgery alternative for one specific group — early, low-risk, hormone-receptor-positive tumors in women 70 and older. Our procedure both predates and extends beyond that.
Cryoablation destroys the tumor by freezing it through a needle, which can preserve the breast and avoid lumpectomy or mastectomy. Intratumoral immunotherapy is then injected into the frozen tumor through the same access. Freezing ruptures the cancer cells intact, releasing their full set of “fingerprints,” and the injected immunotherapy trains the immune system to recognize them — turning the tumor into a personalized in situ vaccine and aiming for the abscopal effect at untreated sites.
A 2024 peer-reviewed study showing breast cryoablation alone can trigger a body-wide immune response further supports the approach. It is considered for early-stage patients wanting a minimally invasive option, and for triple-negative, HER2-positive, recurrent or metastatic disease progressing on standard therapy.
Breast cryoablation: the tumor is destroyed while the breast itself is preserved.
The treated tumor teaches your immune system to recognize the cancer body-wide.
How it works

The two-part procedure.

Part 1

Cryoablation

Image-guided cryoprobes create a controlled ice ball around the tumor, destroying it while preserving the overlying tissue — which is why many patients can avoid lumpectomy or mastectomy. Multiple freeze-thaw cycles maximize cell death and antigen release.

Part 2

Intratumoral immunotherapy

Through the same procedural access, multi-agent immune cocktails tuned to your tumor’s biology — ER, PR, HER2, Ki-67, BRCA, PD-L1, TROP-2 — are injected directly into the ablation bed.

What makes it different

Beyond the cleared indication.

Standard approaches
Our approach
ProSense cleared indication: ER+/PR+/HER2−, ≤1.5cm, age ≥70, with adjuvant endocrine therapy.
Considered across hormone-receptor and HER2 status under clinician review.
Cryoablation alone.
Cryoablation plus multi-agent intratumoral immunotherapy through the same procedural access.
Local control as the goal.
Local control plus systemic immune activation — the abscopal goal.
One specific patient population.
Considered across early, locally advanced, recurrent and metastatic disease case by case.

Why cryoablation for breast.

Cosmetic preservation

The ice ball destroys the tumor while preserving overlying tissue — many patients can avoid lumpectomy or mastectomy entirely.

Broad antigen release

Frozen cells rupture intact, releasing the full protein antigen pool the immune system needs to recognize the cancer.

Two decades of practice

Breast cryoablation here since 2004 — twenty-one years before that device clearance, and combined with immunotherapy since 2014.

Track record

Pioneering breast cryoablation.

2003

Early RFA for breast cancer

Among the first office-based radiofrequency approaches.

2004

Early adopter of breast cryoablation

Consistent with the field’s adoption era (Sabel et al. 2004).

2024

Abscopal effect published

Sardela de Miranda et al. demonstrate cryoablation-induced systemic immune response in breast cancer.

Oct 2025

ProSense cleared for breast cryoablation

The first device-specific clearance — 21 years after our first case.
