neoplasm

increased mammary adenocarcinoma incidence ( J:70564 )

• mammary tumors occur after long latency of at least 13 months of age

• T₅₀ for tumor-free survival is approximately 17 months of age

• at the end of the 20 month observation period, 20 of 26 animals developed mammary tumors; control animals developed none

• tumor pathology corresponded to two characteristic types, solid carcinoma and adenoacanthoma, with a mixture of the two types frequently appearing in the same tumor mass
