In a nationally representative cross-sectional analysis of 6774 women aged 40 to 49 years, overall mammography prevalence was 60.3% with no significant change from 2019 to 2023, while Hispanic women showed a 6.5-percentage-point decline and insurance status remained the strongest enabling factor for uptake.

In 77 biopsy-proven cystic breast lesions, radiologists achieved significantly higher diagnostic accuracy than the KOIOS DS™ AI tool for malignant cystic lesions (92% vs 76% BI-RADS/suspicious classification).

Mayo Clinic oncologists weigh first-line ADC options in metastatic TNBC, tackling biomarker timing, sequencing, and real-world toxicity management from fatigue to ocular events.

A 2-phase U-Net trained on abnormality-focused patches achieved a mean Dice coefficient of 0.58 and detected 77.8% of mammographic lesions on a 55-image test set, with 100% detection of large lesions but resolution-dependent failures for small abnormalities.

GBD 2023 data analysis found India’s age-standardized breast cancer incidence at 28.7 per 100,000 women, with national mortality tripling from 33,151 to 101,621 between 1991 and 2023 and DALYs quadrupling, with the steepest increases in Jharkhand and the highest incidence in Delhi.

This TIP study aims to validate Artera’s MMAI prognostic model—which integrates digital pathology images with clinical data from H&E slides—in patients with early-stage HR+/HER2− breast cancer, with enrollment at UAB anticipated to complete by April 2026.

Using the DISCERN tool, LLMs (ChatGPT and OpenEvidence) scored significantly higher than Google on breast pathology health information quality and reliability, with mean total DISCERN scores of 62.2 and 64.8 vs 35.9, supporting integration of AI tools for patient education.

A prospective subsidized breast biopsy and navigation program at a Kenyan referral hospital achieved same-day CNB in 100% of 104 patients with invasive breast carcinoma, revealing high rates of aggressive subtypes and median 8-month prediagnostic delays, with 16.35% mortality during follow-up.

Intraoperative surgeon-performed PECs block during mastectomy resulted in only 16.6% of patients requiring postoperative opioids, supporting this technique as a fast and effective method of regional analgesia.

In 278 patients with a positive family history of breast cancer followed for a median 96 months, local recurrence, regional recurrence, and CBC risk were comparable to general population rates by SIR analysis, with recurrence risk driven more by biological subtype than family history.

In 52 patients with multifocal upper inner quadrant breast cancer, a modified Würinger central pedicle mastopexy enabled large-volume oncoplastic resections with 80.8% patient satisfaction and significant BREAST-Q quality-of-life improvement, with no major infectious complications.

Advanced oncoplastic breast surgery using multiple pedicles for complex defect reconstruction demonstrated oncologic safety and acceptable complication rates in selected patients undergoing breast-conserving surgery.

Targeted axillary dissection with sentinel lymph node biopsy successfully retrieved all preoperatively identified positive nodes in node-positive breast cancer patients treated with neoadjuvant chemotherapy, with no axillary recurrences observed.

In 21 patients with metaplastic breast cancer receiving neoadjuvant chemotherapy, 48% achieved pCR—higher than prior estimates—with all pCR patients alive and disease-free at follow-up, suggesting modern regimens including pembrolizumab may improve outcomes in this chemoresistant subtype.

In 391 Venezuelan breast cancer patients receiving NACT, normal BMI was associated with higher pCR (31.6% vs 15.8% overweight and 14.7% obese) and significantly better OS at 120 months, supporting BMI as a relevant prognostic and predictive factor.

In this institutional retrospective review, 14.4% of clinically node-negative patients meeting SOUND trial criteria had nodal metastases on SLNB, underscoring the need for careful multidisciplinary decision-making before integrating axillary staging de-escalation into practice.

A retrospective review found progressive adoption of Choosing Wisely guidelines for sentinel lymph node biopsy omission in elderly patients with early-stage breast cancer, with younger age and earlier year of diagnosis as the strongest predictors of biopsy performance.

Four experts discussed how new breast cancer ADC trial results guide treatment sequencing, as well as practical tips for managing Dato-DXd dry eye and other adverse effects.

In 58 patients undergoing excisional biopsy for discordant imaging and pathology, 16% had malignant pathology on excision; palpable lesions were the only factor independently associated with upstage to malignancy (adjusted OR 7.50).

Implementing in-office genetic testing at a diverse MedStar Georgetown breast oncology practice increased genetic counseling completion from 31.3% to 45.2% and lowered mean age at testing from 55.6 to 48.4 years, with gains across all racial groups.

In 167 patients with HR+/HER2− breast cancer after neoadjuvant chemotherapy, lymphovascular invasion, number of positive sentinel nodes, and >50% positive sentinel nodes were the strongest predictors of high axillary burden; a nomogram was developed to guide axillary management decisions.
