Home-AMA: Healthcare 2026: [Interview] A New Way to Fix Lumpectomy Deformities

Among the emerging applications of 3D printing in healthcare, regenerative soft tissue reconstruction has seen the least clinical progress and carries some of the highest unmet patient need.

Every year, hundreds of thousands of women undergo lumpectomy, the surgical removal of a cancerous breast tumor, and the majority walk away cancer-free. What many also walk away with permanently is a contour deformity. For most of these patients, there is simply no good reconstructive option available.

GenesisTissue Inc., an early-stage biotechnology research company, is trying to change that. Their lead product, Regenerative Breast Tissue (RBT), is a bioprinted, personalized, biodegradable synthetic scaffold designed to fill a soft tissue void, support a fat graft, and ultimately make way for the body’s own tissue to take over.

I spoke with Katie Weimer, CEO and Co-Founder of GenesisTissue, about what makes their approach different, what remains unsolved, and what she sees as open questions the field has yet to fully reckon with.

The High Cost of Leaving Defects Uncorrected

Current reconstructive options for lumpectomy patients remain largely inadequate, and Weimer is frank about why. “Surgeons often have no choice but to leave defects uncorrected, resulting in contour deformities, asymmetry, and ultimately a diminished quality of life,” Weimer said.

Standard silicone implants were not designed for the irregular voids left by partial resection, particularly after radiation therapy, which hardens and damages surrounding tissue.

For full-breast reconstruction and cosmetic augmentation, they carry their own well-documented risks, among them infection, capsular contracture, rupture, and malposition. The gap has persisted for decades, and the patients who fall into it have not gone unnoticed. “We regularly get emails from patients asking when our solution will be available,” Weimer said.
