Gene therapy is a revolutionary medical technique that aims to treat or prevent diseases by modifying or replacing faulty genes. This approach is particularly effective for genetic disorders and certain cancers. By introducing healthy genes into a patient’s cells, gene therapy can restore normal function and alleviate symptoms.

In contrast, supportive therapy focuses on enhancing the quality of life for patients without directly addressing the underlying disease. It includes pain management, psychological support, and nutritional assistance. While supportive therapy helps manage symptoms and improve overall well-being, it does not cure or treat the disease itself. Thus, the key difference lies in gene therapy’s active intervention at the genetic level, while supportive therapy provides care and comfort.
