- Data highlight how screening and diagnostics enable earlier detection, more precise treatment decisions, and improved patient outcomes from risk to remission
- New MRD data from the PARTNER study demonstrate enhanced sensitivity in early triple-negative breast cancer
- Early MCED prospective data show low anxiety and minimal psychological burden in real-world use
ABBOTT PARK, Ill., May 26, 2026 /PRNewswire/ -- Abbott (NYSE: ABT) will present 11 abstracts featuring new evidence across the cancer care continuum at the American Society of Clinical Oncology (ASCO) Annual Meeting, taking place May 29 – June 2, 2026, in Chicago. The presentations showcase the breadth of Abbott's integrated cancer diagnostics portfolio and demonstrate how its tests support critical decision points—from identifying risk and detecting disease earlier to guiding treatment and monitoring for recurrence.
The data indicate a shift in oncology toward more precise detection, improved personalized care, and clearer treatment decisions without adding patient burden or stress.
"Cancer care is at an inflection point, and diagnostics are playing an increasingly central role in how the disease is detected, treated and managed," said Jake Orville, senior vice president, Abbott's cancer diagnostics business. "By combining tools used for screening, early detection, treatment guidance and recurrence monitoring, we're helping clinicians make more informed decisions at every stage of cancer care, from risk through remission."
