Abstract
A study of international cancer risk differences provided an opportunity to evaluate the Greegor test on an outpatient basis. 1,539 Japanese-American men performed the test, which identifies blood in feces through the use of guaiac-impregnated slides. Subjects having occult blood were asked to repeat the procedure on a meat-free, high-bulk diet. Four asymptomatic cancers were among 25 gastrointestinal lesions subsequently identified in individuals with positive, restricted-diet guaiac tests. In three of the four cancer cases, only weakly positive guaiac reactions were found.
