The Power of Genetic Tests
Genetic tests can identify specific changes in genes that increase cancer risk. This information can guide doctors in deciding the best treatment plans. For instance, certain drugs are more effective in patients with specific genetic mutations.
Choosing the Right Treatment
For those with a BRCA1 or BRCA2 variant, treatments like PARP inhibitors can be particularly effective. These drugs target cancer cells' ability to repair DNA, which is often compromised in these patients. This approach can extend disease-free survival in some cancer cases.

When to Consider Genetic Testing
Patients with a family history of cancer or personal history of certain cancers are prime candidates for genetic testing. Performing these tests can shed light on available treatment paths and preventive measures. It's crucial to work with a healthcare provider to determine the best course of action.
