VOICES: DR. JUDAH FOLKMAN

TITLE
Director, Surgical Research Laboratories, Children's Hospital of Boston. 65.

CONTRIBUTIONS
Folkman worked nearly 30 years to prove that blocking growth of tumor-nourishing blood vessels could fight cancer. Recently, he found natural inhibitors that wipe out tumors in mice--sparking a race for new treatments.

IN HIS WORDS
''As long as there is an unconquered disease, we have an obligation to pursue research... [For now], if you have cancer and you are a mouse, we can take good care of you.''
