Biomarkers are essential for personalized medicine, where treatment is tailored to the individual's specific cancer characteristics:
- Targeted Therapies: Some biomarkers can indicate whether a patient will respond to specific targeted therapies. For example, EGFR mutations in lung cancer can predict responsiveness to EGFR inhibitors.
- Immunotherapies: Biomarkers such as PD-L1 expression can help determine if a patient will benefit from immunotherapy.
