Genetic Testing: Unraveling the Mysteries of Your DNA
Published: Apr 05, 2024
Genetic testing can reveal important information about your risk for certain cancers and help guide treatment decisions.
What is Genetic Testing?
Genetic testing involves analyzing your DNA to look for changes that might increase your risk for diseases like cancer. It can identify specific mutations in genes such as BRCA1 and BRCA2 that are linked to higher cancer risks. This information can be crucial in planning treatment and preventive strategies.
The Testing Process
The process usually involves a simple blood or saliva test. The results can take a few weeks and are reviewed by healthcare professionals to determine the best course of action. It's important to undergo genetic counseling before and after testing to fully understand the implications of the results.
Why Get Tested?
If you have a family history of certain cancers, genetic testing can provide valuable insights into your own risk. It can help you and your healthcare provider make informed decisions about your health. This might include increased surveillance or preventive measures to reduce your risk.
