Biotechnology has become an essential part of modern cancer research by helping scientists understand how cancer develops, spreads, and responds to treatment. Through advances in genetics, molecular biology, and laboratory technologies, researchers can identify disease-related changes with greater accuracy than ever before. Biotechnology also supports the development of targeted therapies, diagnostic tests, and personalized treatment approaches that aim to improve patient outcomes while reducing unwanted side effects. As scientific knowledge continues to expand, biotechnology remains a valuable tool in advancing cancer research, encouraging innovation, and contributing to better prevention, earlier detection, and more effective healthcare solutions around the world.
