In the current study, scientists have investigated whether smartphone usage for a period of 20 years has any effect on the incidence and mortality related to malignant brain cancers in Taiwan. Similarly, the compound annual growth rates of smartphone users, brain cancer incidence, and brain cancer deaths were estimated to be 1.95, 1.07, and 2.30, respectively, during the study period. These observations indicate a positive growth rate for all estimated parameters.

Study significance The study finds an increasing trend in the number of smartphone users during 2000 – 2019 in Taiwan, which is accompanied by a slight increase in brain cancer incidence and mortality rates. In other words, the study finds a weak and non-significant association between smartphone usage and brain cancer incidence and mortality.

Furthermore, negative environmental influences and various lifestyle elements could also play a part. Consequently, for a precise, comprehensive analysis of MNB incidence and mortality root causes, all these factors warrant consideration. Also, our study did not delve into the age-related distribution facets of mobile users to determine their correlation with MNB, a pivotal omission as cancer incidence typically escalates significantly among middle-aged individuals and seniors.
