Normal use of microwave ovens produces radiation that generally does not increase the risk of cancer. Usually microwave oven radiation value belongs to the normal range of radiation, as long as the radiation level does not exceed 833 milligauss, generally will not cause harm to the human body as well as the impact. The general microwave oven radiation is about 278 milligauss, but also do the radiation protection measures, will not let the microwave oven radiation value leakage, so the reasonable use of microwave ovens generally will not increase the risk of cancer. The specific cause of cancer is still unclear, the main reasons may include alkylating agents, acylating agents, polycyclic aromatic hydrocarbons, ethylnaphthalene amine, aflatoxin and other chemical factors, ionizing radiation and other physical factors, cancer-causing viruses and other biological cancer-causing factors, as well as hereditary factors, generally has nothing to do with the use of microwave heating. In conclusion, the use of microwave oven-ready and safe containers is generally harmless to humans and does not increase the risk of cancer.
