  * An ADVANCED premalignant lesion defined as the presence of at least one of the following: moderate dysplasia or severe dysplasia (excluding CIS)
* The subj is \> 18 yrs of age
* The subj's life expectancy is \> 12 wks and Zubrod performance status is 0 or 1 (Appendix VIII).
* The subj meets the following lab eligibility criteria during a time not to exceed 4 wks prior to randomization.

  * Hemoglobin level above 10g/dL for women and above 12g/dL for men.

  * is willing to limit aspirin use to \< or = 120 mg po per d (typical cardioprotective dose in India) or \< or = 80 mg po per d (typical cardioprotective dose in the US) for the duration of the study, and is willing to abstain from chronic use of all NSAIDs and COX-2 inhibitors for duration of study. Chronic use of NSAIDs is defined as a frequency of \> or = 3 times/wk AND for more than a total of 14 ds a yr.
