Antioxidants are chemicals that break down or neutralize the damaging effects of free radicals - chemicals produced as a byproduct of normal cellular metabolism.

A fundamental premise in cancer therapy is trying to identify how the metabolism of cancer cells differs from normal tissue. When differences are identified, it often paves the way for treatments that will disrupt the cancer's metabolism while sparing normal tissue.

Oppression

Now dreams

Will come back,
And the song
Break
Its jail.
