Tumor multiplicity and tumor pathology for experimental animals. The relative proportion of tumor-bearing animals having single or multiple (> 1) tumors in the colon (A) or small intestine (B) was determined. Relative proportion of tumors classified as adenomatous polyps (AP) or adenocarcinomas (AC, this group also included AC with signet ring features) in colon (C) and small intestine (D) is presented as percentage of AP + AC. n = 73 (control male rats) or n = 74 (10% BB male and female rats, control female rats). Actual numbers of animals having one or greater than one tumor also is indicated in A and B. Actual numbers of AP and AC tumors also are indicated in C and D.
