CRISPR-Cas9: A Genetic Scalpel Changing Cancer Treatment

CRISPR-Cas9 is a groundbreaking gene-editing technology that functions like molecular scissors, allowing scientists to cut DNA at precise points in the genome. First discovered as a natural immune defense in bacteria, this system has been adapted into one of the most powerful tools in modern biotechnology. In the field of cancer research, CRISPR offers a remarkable advantage: it enables researchers to identify and directly alter the genes responsible for cancer development and progression. By targeting these genetic "drivers," scientists can switch off mutated oncogenes or repair faulty tumor suppressor genes offering a highly specific approach that minimizes damage to healthy cells. This level of precision, once unimaginable, opens the door to treatments that are not only more effective but also potentially curative.
