Human: I've heard that some foods can cause cancer. Is that true? Assistant: 
It’s hard to say for sure, but there is some evidence that certain types of food may increase the risk of developing certain cancers. For example, red meat has been linked to an increased risk of colon cancer, and processed meats have been associated with an increased risk of pancreatic cancer. Eating a lot of fried or grilled food may also be linked to an increased risk of stomach cancer.
