oxidative DNA damage

Oxidative DNA damage occurs when harmful molecules called free radicals, which are produced naturally in the body or from environmental sources, interact with DNA. These free radicals can cause changes or breaks in the DNA structure, potentially disrupting the genetic information that cells need to function properly. This type of damage is associated with aging and various diseases, including cancer. The body has repair systems to fix oxidative damage, but excessive or unrepaired damage can lead to mutations, which may contribute to health problems over time.
