Practical Applications
## What is Genetic Testing?
Genetic testing analyzes your DNA to look for changes that might affect your health.
## How is it Used?
- Detecting genetic disorders before symptoms show up.
- Predicting risks for diseases like cancer or heart disease.
- Guiding medical treatments based on your genetic makeup.
## Personalized Medicine
Doctors can now use your genetic information to choose the best medicine and dosage for you—making treatment safer and more effective.
### Ethical Considerations
As genetic testing becomes more common, it's important to think about privacy and how this information is used.
Examples
- A person learns they have a higher risk of breast cancer and takes preventive steps.
- Doctors use a patient’s genetic profile to select the most effective asthma medication.
