Abstract
Every patient's tumor requires personalized cancer therapy because it matches treatments to individual molecular profiles to reach optimal treatment effectiveness and reduce treatment side effects. The combination of genomic tools with bioinformatics allows doctors to perform extensive tumor analysis for identifying valid genetic alternations which then enable targeted therapy administration to deliver successful patient results. Results from this research demonstrate how genetic data established personalized cancer treatment leading to improved response rates and decreased adverse effects than standard therapies. The utilization of genetic data in diagnostics faces two primary obstacles which include the intricate nature of tumors along with resistance initiation and ethical complications stemming from collection and patient protection concerns. The necessary advancement of genomic sequencing combined with bioinformatics analysis and artificial intelligence applications will help to break through these barriers. Personalized treatment strategies become more effective for diagnosis accuracy and therapy selection through predictive modeling that employs machine learning algorithms. By integrating multiple biological data sets transcriptomics with proteomics and metabolomics researchers gain a deeper understanding which supports more efficient drug development. These developing technologies will make personalized oncology treatments more precise while spreading to more medical centers which will revolutionize one-size-fits-all cancer treatment into precise patient-specific interventions. Modern cancer treatment methods will transform due to this newly available information to improve both patient survival possibilities and their quality of life across the world.
