Gene therapy is a medical technique that involves the use of genetic material to treat or prevent diseases. This can include replacing a faulty gene with a healthy one, introducing a new gene into the body to help fight a disease, or modifying existing genes to improve their function. Gene therapy has the potential to treat a wide range of genetic disorders, as well as certain types of cancers and other diseases. Researchers continue to explore and develop new ways to utilize gene therapy in the treatment of various medical conditions.
