New evidence backs Hologic's ai-powered mammography technology for detecting challenging cancers. Results highlight AI's potential to aid radiologists in identifying diverse breast cancer subtypes, including invasive lobular cancer MARLBOROUGH, Mass., April 20, 2026 - New research on Hologic's AI-driven breast cancer detection technologies, including a study focused on invasive lobular cancer, was presented at the Society of Breast Imaging (SBI) Symposium over the weekend in Seattle, Washington. "Invasive lobular cancers are more challenging to detect on a mammogram because of their unique characteristics," said Mark Horvath, President of Breast & Skeletal Health Solutions at Hologic. "In the study, AI maintained high sensitivity for flagging these cancers, including some that had been interpreted as negative at a prior screening. These data add to a growing body of evidence that AI can act as a powerful supportive tool for radiologists as they review the full spectrum of breast cancers." In this retrospective, single-center study, researchers at Massachusetts General Hospital in Boston reviewed invasive lobular cancer cases diagnosed over a 10-year period and grouped them into two categories: those detected by a radiologist during a routine screening exam (195 total) and "false negatives" that were diagnosed within a year of a routine screening exam initially interpreted as negative (44 total). Researchers then used Hologic's Genius AI(R) Detection solution to retrospectively analyze all 239 cases. In this cohort, the technology identified and correctly localized close to 90% of the confirmed invasive lobular cancers.[1] New research suggests that, on average, 1 in 20 women worldwide will be diagnosed with breast cancer in their lifetime and, that if current rates continue, by 2050 there will be 3.2 million new breast cancer cases and 1.1 million breast cancer-related deaths per year.[2] About 10-15% of all breast cancers are invasive lobular cancers,[3] while ductal cancers that originate in the milk ducts of the breast - such as invasive ductal carcinoma and ductal carcinoma in situ - occur more commonly. Invasive lobular cancer arises in the milk-producing glands (lobules) of the breast and, because of its unique biology and tendency to grow in a linear pattern, it may be more challenging to see on mammography. This may lead to later detection and a more advanced stage at diagnosis. The AI algorithm also identified 43% of the invasive lobular cancer cases initially interpreted during routine screening as negative.[1] Of note, as a retrospective analysis at a single institution, the study did not evaluate how use of AI in real time clinical practice would affect recall rates, biopsy outcomes or patient management. Also at the Society of Breast Imaging Symposium, Hologic hosted a lunch and learn discussion with breast imaging experts focused on implementation of 3DQuorum(R) imaging technology, which uses AI to reduce the number of 3D imaging "slices" radiologists need to review without compromising image quality, sensitivity or accuracy.[4,5] Study Limitations The MGH study did not assess false-positive rates, recall rates or biopsy outcomes, and its single-center design may limit generalizability. AI performance was evaluated retrospectively and did not influence real-time radiologist decision-making; therefore, the observed gains represent a theoretical upper bound rather than a measured clinical impact. Additionally, the cohort included only patients with invasive lobular cancer, precluding comparison with other histologic subtypes.

GE HealthCare delivered the strongest fourth-quarter performance among medical devices and imaging stocks, whilst Hologic posted the weakest results against analyst estimates, according to a sector review. The four medical devices and imaging companies tracked reported slower fourth-quarter growth overall, though revenues collectively beat consensus estimates by 3.5%. Share prices have struggled since results, falling an average of 13.5%. Hologic, which develops diagnostic products and medical imaging systems focused on women's health, reported revenues of $1.05 billion, up 2.5% year on year but missing analysts' expectations by 2.1%. The company significantly missed both revenue and earnings estimates. Despite the disappointing results, Hologic shares have risen 1.4% since reporting and currently trade at $76.05. GE HealthCare, spun off from General Electric in 2023, outperformed peers in the quarter.
