Cellular repair is the process by which cells fix damage to their structures and functions. This damage can occur due to various factors, including UV radiation, toxins, or oxidative stress. Cells have specialized mechanisms, such as DNA repair pathways, that help identify and correct errors, ensuring proper functioning and maintaining overall health. When cells undergo repair, they can restore their ability to grow, divide, and perform essential tasks. Effective cellular repair is crucial for preventing diseases, including cancer, and for promoting longevity. Understanding these processes can lead to advancements in medical treatments and therapies aimed at enhancing cellular health.
