We studied the effect of dietary fat levels on the induction of mammary cancer by 350 rads total-body x-radiation given to noninbred albino Sprague-Dawley rats at 50 days of age. Compared to rats on a low-fat (LF) diet (5% lard), rats on a high-fat (HF) diet (20% lard) from 30 days of age had more tumors, with a higher multiplicity of carcinomas per rat. LF-fed groups exhibited a longer median tumor latency period than did HF-fed groups. A similar trend toward more tumors with an earlier time of death was seen in rats given single iv doses of 50 mg 1-methyl-1-nitrosourea/kg and fed an HF diet as compared to an LF diet.
