Precision Oncology

Every patient’s cancer is different—and understanding those differences can change everything. By exploring its complexity, researchers are designing treatments that fit the person, not just the diagnosis.

Understanding Precision Oncology

MCW researchers are studying cancer in a whole new way—right down to its building blocks. Using genomics (DNA changes), epigenomics (chemical switches that turn genes on or off), and transcriptomics (patterns of gene activity), they are tracing the processes that drive tumor growth, treatment resistance, and progression. Even cancers that appear similar under a microscope can behave very differently, and this multi-omics approach helps explain why.

Supported by the Linda T. and John A. Mellowes Center for Genomic Sciences and Precision Medicine, investigators combine molecular understanding with large-scale datasets and computational analyses. This helps them detect subtle patterns that might otherwise go unnoticed, giving a detailed view of what's happening in each patient's cancer.

These discoveries are already guiding care in specialized settings such as the Rare Cancer and Precision Medicine Clinic, where detailed tumor analysis helps clinicians explore additional treatment options for cancers that are complex, rare, and not well understood. When standard therapies fall short, this approach allows clinicians to tailor care and offer alternatives that are informed by the latest scientific evidence.

By connecting these discoveries directly to patient care, precision oncology is making cancer care smarter, more targeted, and increasingly personalized—redefining how treatment decisions are made so patients receive care as unique as they are.
