Aluminum itself is not known to cause cancer, but in the list of carcinogens published by the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO), aluminum products are defined as a group of carcinogens with a certain risk of causing cancer. Aluminum is a metallic element with a wide range of uses, and can be used to make aluminum pots and pans, lunch boxes, and other everyday items. Normally, human organs and tissues contain trace amounts of aluminum, and if aluminum products are used in the right way, they are generally not carcinogenic. However, excessive intake of aluminum can lead to excess aluminum in the body, causing damage to endocrine, hematopoietic, respiratory and bone parts, leading to tissue cell lesions. Long-term development may increase the risk of cancer. At the same time, long-term intake of aluminum may also cause damage to the nervous system, leading to memory loss, and in severe cases, may even affect intelligence.
