Basically there is no food that carries cancer cells, world cancer experts agree that it is healthy cells in the body that turn into cancer cells because of the effects of conditions in the body due to the influence of a number of things such as foods that have carcinogenic effects. Changes occur gradually, usually starting from the destruction of healthy cells which then progress to the regeneration of aberrant cells. So it is not correct to say that catfish carry cancer cells in the body. Even if catfish has the effect of increasing the risk of cancer, it is most likely because there is a carcinogenic effect carried by fish. Some suspicions come from how catfish live, both in the wild and in rearing ponds. Because catfish have excellent resistance to a dirty environment, even a polluted environment. They are sometimes reared with waste food which is feared to be a carrier of carcinogenic effects in fish meat. One source that later became viral was the news of America's rejection of catfish from China. Unfortunately the news that arrived in Indonesia did not present the actual news. While in Indonesia the news raised about the pattern of rearing by feeding pig manure, actually according to a source abcnews.go.com, the United States' refusal was based on field findings that catfish from China contained anti-fungal, anti-bacterial and types of chlorine compounds which were considered dangerous and natural. carcinogen. This actually indicates that fisheries in China are so modern that they put a number of chemical compounds in their ponds in inappropriate amounts. It also invalidates the information that catfish from China were rejected as a result of being fed pig dung.
