Gene therapy is a promising technique that aims to treat or prevent diseases by modifying an individual's genetic material. It involves introducing new genes into the body to replace or supplement faulty genes. While gene therapy holds great potential to treat genetic disorders like cystic fibrosis and provide targeted treatment, it also faces challenges. Gene therapy has safety concerns as the field is still evolving. It raises ethical issues regarding genetic manipulation. Gene therapy treatments can also be expensive due to their complex nature. Further research is needed to address these disadvantages before gene therapy can be widely adopted.
