What are free radicals that cause cancer?

ANSWER

Free radicals are one of the by-products of oxygen use by every cell in our body. These substances damage the body's cells through oxidation, the same process that rusts metal and turns butter rancid. Oxidation has also been shown to contribute to heart disease, cataracts, aging, and infections.
