Tumor induction in 7.12-dimethylbenz[a]antracene treated groups in relation to diet

Diet	Tumor incidence (%)1	Number of tumors in one rat	Maximum tumor weight in one rat in group (g)	First week at onset
1. Standard diet	9/9 (100)	1-5	12	15
2. Zinc 6.9 mg/mL (231 mg Zn/kg diet)	9/9 (100)	1-5	20	15
3. Zinc 6.9 mg/mL (231 mg Zn/kg diet) and resveratrol 0.1 mg/mL (0.2 mg/kg bw)	10/10 (100)	2-10	30	13
4. Zinc (6.9 mg/mL) (231 mg Zn/kg diet) and genistein 0.1 mg/mL (0.2 mg/kg bw)	10/11 (91)	1-6	15	15
5. Copper 1.3 mg/mL (42.6 mg Cu/kg diet)	9/9 (100)	1-5	7	14
6. Copper 1.3 mg/mL (42.6 mg Cu/kg diet) and resveratrol 0.1 mg/mL (0.2 mg/kg bw)	12/12 (100)	2-6	11	14

The date refer to tumors evaluated at 20 weeks of the animals' age (decapitation time).

¹ Tumor incidence is expressed as the number of tumor-bearing rats over total number of rats in the group.
