Cancer occurs when the DNA in a human cell becomes damaged or mutates in such a way that the body is unable to identify the problem or repair it. These abnormal cells can grow out of control and form tumours or masses that invade healthy tissue and organs.
Traditionally, cancer has been categorized according to its location in the body, such as lung cancer, breast cancer, etc., and most patients with a particular tumour type are treated based on its categorization by location in the body.
Cancer researchers have identified specific genes that are related to cancer growth. As a result, cancer can now also be categorized by the underlying changes in DNA, or genomic alterations that drive the tumour’s growth.1
Targeted therapy is a type of cancer treatment designed to be specific to tumours that harbour the appropriate genomic alteration. Targeted therapy is a growing part of many cancer treatment regimens.2
Genomic testing or profiling identifies the underlying DNA alterations that may be driving the tumour’s growth.3 This information may help physicians understand which potential next steps are available for a patient based on their tumour’s unique genomic profile.
Comprehensive genomic profiling with FMI also looks at complex genomic signatures that most standard tests can't assess. The latest science indicates that these new kinds of biomarkers can help a physician better understand the potential role immunotherapies may play for any given patient's disease.
