Key Points

The SLNB-omission analysis found that each 99mTc procedure generated about 0.54 kg of CO2-equivalent emissions and 92 grams of waste, while omitting the procedure reduced reimbursement by roughly €950 per case and freed an estimated 52.5 operating-room hours annually.

The SLNB study cautioned that combining sentinel-node omission with radiotherapy de-escalation is a potential next step, but remains unvalidated; patients in both the INSEMA and SOUND studies received whole-breast radiotherapy.

In the prospective FES-PET/CT trial, 45 women were recruited across 17 U.S. centers between January 2023 and May 2024; imaging changed management for 17 patients, or 37.8%. FES, marketed as Cerianna, was FDA-approved in 2020 as an adjunct to biopsy for detecting ER-positive lesions.

The mammography commentary cited the Cochrane review’s illustrative balance of benefits and harms: assuming a 15% mortality reduction, one woman per 2,000 screened would avoid breast-cancer death over 10 years, while 10 would be overdiagnosed and treated and 200 would experience false alarms. It also said the mortality benefit disappeared in the higher-quality, adequately randomized trials reviewed by Peter Gøtzsche.

The advocacy program’s 2026 opening session, “From Guidelines to Bedside: Decision-Making in Monotherapy and Combination Breast Cancer Treatment,” features breast oncologist Neil Iyengar and patient-advocacy leader Mary Jimenez, with registration offered for both live and virtual participation.
Breast cancer treatment is moving toward personalized decisions that weigh effectiveness, side effects, and quality of life OncoDaily. Recent evidence shows doctors can now safely skip lymph-node surgery for selected older patients with early hormone-positive tumors, freeing up operating rooms and reducing unnecessary procedures. Meanwhile, new imaging technology is changing second-line treatment plans for about 38% of patients with advanced disease, and experts are calling for individualized choices about chemotherapy for younger women.
These shifts reflect a broader push toward tailored care rather than one-size-fits-all protocols OncoDaily. Doctors and patients are weighing not just survival odds but also long-term harms, fertility concerns, and whether simpler treatments work just as well as aggressive combinations.
Skipping Lymph-Node Surgery for Older Patients with Early Tumors
For selected older women with early, hormone-positive breast cancer, omitting sentinel lymph-node biopsy is now supported by evidence OncoDaily. The procedure removed about 0.54 kilograms of carbon-equivalent emissions and 92 grams of waste per case. Skipping it also saved roughly €950 in reimbursement per patient and freed an estimated 52.5 operating-room hours annually OncoDaily.
Doctors and patients should focus on what truly matters: avoiding morbidity and preserving eligibility for future drug therapies OncoDaily. The environmental and cost benefits, while real, are secondary to patient safety. However, experts caution that combining this omission with radiation de-escalation remains unproven and needs validation before becoming routine OncoDaily.
New PET Scan Reshapes Metastatic Cancer Treatment Plans
A novel PET imaging agent called Cerianna changed treatment decisions for 17 out of 45 women (37.8%) with advanced, hormone-positive breast cancer OncoDaily. Researchers recruited patients across 17 U.S. centers between January 2023 and May 2024. The scan, which detects estrogen receptors, increased oncologists' confidence in choosing second-line therapies after first-line hormone drugs stopped working OncoDaily.
Cerianna was approved by the FDA in 2020 as a tool to detect estrogen-receptor-positive lesions OncoDaily. This real-world evidence shows the scan translates into clearer clinical choices when doctors face difficult decisions about what drug to try next.
Individualized Choices for Younger Women with Hormone-Positive Tumors
Premenopausal women with hormone-positive breast cancer need personalized treatment plans that account for chemotherapy, hormone therapy, adherence challenges, safety, and fertility OncoDaily. Treatment benefits and long-term harms vary widely across patients, and younger women remain underrepresented in many landmark trials OncoDaily. One-size-fits-all guidelines cannot address this diversity.
Clinicians and patients should jointly weigh whether single-drug therapy or combination treatment makes sense for each person OncoDaily. A new advocacy initiative launching in 2026 will feature expert oncologist Neil Iyengar and patient leader Mary Jimenez discussing bedside decision-making, with both in-person and virtual attendance options available OncoDaily.
Screening Benefits and Risks Require Candid Patient Conversations
Mammography screening offers both clear benefits and real harms that patients deserve to understand. Assuming a 15% mortality reduction, one woman per 2,000 screened avoids breast-cancer death over 10 years Alethonews, but 10 women are overdiagnosed and treated unnecessarily, and 200 experience false alarms Alethonews.
Controversy remains about older, lower-quality mammography trials Alethonews. When researcher Peter Gøtzsche reviewed only the higher-quality, adequately randomized trials for the Cochrane Collaboration, the mortality benefit disappeared Alethonews. This gap underscores why informed screening discussions—not pressure or paternalism—must accompany discussions of early detection benefits.
