Once formed, these free radicals can have a genuinely destructive impact on a cell. Those radicals which do not cause death to the cell can stimulate the growth of cancer when they interact with and cause damage to the DNA within the cell. Scientific show suggests that these oxygen free radicals play important roles in the expansion of tumors and the acquisition of malignant properties.

The oxygen free radicals are atoms or groups of atoms with unpaired electrons formed between the interaction of oxygen and certain molecules. These radicals immediately attach themselves to other c ells in order to balance out the number of electrons and become stable. Once formed, these free radicals can have a very destructive impact on a cell. Those radicals which do not cause death to the cell can stimulate the growth of cancer when they interact with and cause damage to the DNA within the cell. Scientific evidence suggests that these oxygen free radicals play important roles in the expansion of tumors and the acquisition of malignant properties.

The antioxidant molecules interact with the oxygen free radicals and halt the spread of cancer causing cells with damaged DNA before other vital molecules are damaged. The main micronutrient antioxidants are vitamin E, beta-carotene, and vitamin C. Additionally, a trace metal known as selenium is required for the proper functioning of one of the bodys anti oxidant enzyme systems. Since the body cannot produce these micronutrients itself, they must be ingested through the diet.
