What Is Comprehensive Genomic Profiling (CGP) and When Can It Be Helpful?

More and more people diagnosed with cancer hear about genomic testing or comprehensive genomic profiling (CGP). But what exactly does it mean, and how can it support cancer care?

Cancer treatment has evolved significantly over the past decade. While treatment decisions were traditionally based primarily on where the cancer originated—such as the lung, breast, or colon—modern oncology increasingly considers the unique molecular characteristics of each patient’s tumour.

This approach, often referred to as precision oncology, uses genomic information to help physicians better understand the biology of an individual’s cancer and identify treatment options that may be appropriate for that specific tumour.
