The free-radical theory states that organisms age and cancers for because cells accumulate free radical damage over time. In the 21 st century with so many people getting cancer, researchers have stepped up their research in order to find a cause. Free radicals could be the explanation that they are looking for. Free radicals, like I said earlier are atoms with one or more unpaired electrons. They are not specific to any charge. They could be positive, negative, or neutral. Because they have unpaired electrons, free radicals are very reactive. They react with other atoms in the body and steal there electron to make itself stable, thus making that atom a free radical. Out of the many free radicals in existence, biologists are most concerned about are the oxygen radicals. It has two unpaired electrons making it a very aggressive radical.
