The study investigates how DDT affects liver cancer development in rats that have been exposed to aflatoxin B1 (AFB1).
In the first experiment, rats exposed to both AFB1 and DDT showed a higher number of neoplastic nodules compared to those only given AFB1.
The second experiment indicated that rats exposed to AFB1 followed by a higher DDT dosage developed more altered liver foci and tumors over time, suggesting that DDT slightly increases the cancer risk associated with AFB1 exposure.
Overall, the findings highlight a potential interaction between DDT and AFB1 that may enhance hepatocarcinogenesis.
