Gene therapy is an innovative area of medical research that aims to treat or prevent diseases by modifying, replacing, or repairing genes within a person's cells. Over the past few years, scientific advances have expanded the potential applications of gene therapy beyond rare inherited conditions. Researchers are exploring its use in cancer treatment, neurological disorders, cardiovascular diseases, and regenerative medicine. While challenges related to safety, accessibility, and long-term effectiveness remain, ongoing studies continue to improve understanding of this technology. Learning about emerging applications of gene therapy helps highlight how modern medicine is evolving to address complex health conditions.
