Cancer drug discovery is a dynamic and complex field focused on identifying and developing new therapeutic agents to combat cancer. This process involves understanding the molecular and genetic basis of cancer, identifying potential drug targets, and designing compounds that can specifically target cancer cells while minimizing harm to normal cells. Advances in genomics, biotechnology, and computational modeling have significantly accelerated the discovery and development of novel cancer drugs. Through rigorous preclinical and clinical testing, promising compounds are evaluated for their efficacy and safety, aiming to provide more effective and personalized treatment options for patients battling this diverse and challenging disease.
