Today's data selection: How high is the risk of cancer in laboratories; the number of people who have passed the national examination has doubled compared with 2021

How high is the risk of cancer in laboratories? Experts remind us to pay attention to laboratory safety management

Recently, Sun Yat-sen Memorial Hospital of Sun Yat-sen University said that three people who worked and studied in the laboratory of its breast tumor center were diagnosed with cancer, and these people were relatively young, which aroused strong public attention.

Is this relevant to the lab environment? The jury is still out. How high is the risk of laboratory cancer? This has also triggered widespread discussion among the outside world. Regarding this topic, the reporter interviewed many professionals.

There is much speculation about whether there is a connection between cancer patients and laboratory or reagent contact.

A person engaged in oncology drug research and development in Foshan, Guangdong, told China Business News that in scientific research, using chemical agents to induce cancer animal models is a very common modeling method. In the laboratory, commonly used chemical inducers include methylnitrosourea, methylnitrosoguanidine, etc. However, there is currently a lack of direct human test data on whether these chemical inducers can cause cancer in humans in a short period of time. Cancer takes a long time to occur, spanning from ten years to decades. Under the premise of non-standard use, carcinogens in the laboratory accidentally extend into the human food chain due to environmental pollution, which may promote the occurrence of human cancer earlier, but canceration also takes a long time. Therefore, it is actually difficult to draw a conclusion whether there is a strong connection between the cancer patient and the laboratory or reagent contact.
