Definition

Cancell (Entelev or Cantron), is a liquid that has been produced in various forms, principally by two manufacturers, since the late 1930s. The exact composition of Cancell/Entelev is unknown, but the U.S. Food and Drug Administration (FDA) has listed the components as inositol, nitric acid, sodium sulfite, potassium hydroxide, sulfuric acid, and catechol. NCI studies determined that the mixture lacked substantial antitumor activity. (from CancerNet)
