The study cited is "Global trends in incidence, death, burden and risk factors of early-onset cancer from 1990 to 2019". BMJ Oncology. 2023. Important context lacking here is that a scientist called Jianhui Zhao, has been caught cheating previously in a 2018 article about cancer. Results didn't matched the experiments. https://pubmed.ncbi.nlm.nih.gov/33901310/ https://pubmed.ncbi.nlm.nih.gov/33901310/ "certain of the Transwell cell migration and invasion assay data shown in Fig. 3B were strikingly similar to data appearing in different form in a pair of other articles written by different authors at different research institutes, one of which had already been published elsewhere prior to the submission of this paper to International Journal of Molecular Medicine" --If-- this author from the Second Affiliated Hospital on Zhejiang (China) is the same person that worked previously on the Hospital of Jilin University (China), we should take the results claimed here with a healthy dose of caution.
