The role of genetic testing in cancer prevention and treatment

Cancer is a complex disease influenced by many factors, including genetics. At the Mays Cancer Center, home to UT Health San Antonio MD Anderson Cancer Center, we recognize the importance of understanding genetics’ impact on increasing cancer risk. By offering advanced genetic testing services, we empower our patients with knowledge that can guide prevention and treatment strategies.

“Genetic testing is important because it doesn’t just impact your individual care; it can affect family members and future generations to be better equipped in the battle against cancer,” says Lauren Mills, MS, CGC, a certified genetic counselor at Mays Cancer Center. 

Here’s how genetic testing plays a pivotal role in cancer care and how our dedicated genetic counselors support you every step of the way.  

Understanding genetic testing in cancer  

Genetic testing analyzes your DNA to identify mutations you may have been born with that may increase your risk of developing cancer. These mutations can be inherited. The process includes genetic analysis of a blood or saliva sample, interpretation of results by our genetic counselors, and a risk assessment to determine the likelihood of developing cancer.  

Based on the findings, personalized screening and prevention strategies are recommended. The results guide treatment decisions for those already diagnosed, including targeted therapies, appropriate surgical options, and future screening needs. The testing also has implications for family members, who may share the genetic risk. Monitoring and follow-up care is essential for individuals with identified risks, ensuring proactive management and care.
