The use of digital technology has grown rapidly during the last couple of decades. During use, mobile phones and cordless phones emit radiofrequency (RF) radiation. No previous generation has been exposed during childhood and adolescence to this kind of radiation. The brain is the main target organ for RF emissions from the handheld wireless phone.

An evaluation of the scientific evidence on the brain tumor risk was made in May 2011 by the International Agency for Research on Cancer at the World Health Organisation. The scientific panel

reached the conclusion that RF radiation from devices that emit nonionising RF radiation in the frequency range 30 kHz-300 GHz is a Group 2B, that is, a “possible” human carcinogen.

 With respect to health implications of digital (wireless) technologies, it is of importance that neurological diseases, physiological addiction, cognition, sleep, and behavioral problems are considered in addition to cancer. Well-being needs to be carefully evaluated as an effect of changed behaviour in children and adolescents through their interactions with modern digital

technologies.

Furthermore, research conducted by Hardell (2018) about the impact of mobile phones on children and adolescent health discovered that brain development is very sensitive to poisons.

The urgency of using the mobile phone by adults near young children may increase their attraction to the experience of using it, as well as many adults allow them to hold it to play or fun, and this enhances the likelihood of the child continue using the mobile phone in the period of growth and development and until attaining the age of majority.

 Because the children use mobile for longer time when they grow older  various health problems such as neurological diseases, physiological

addiction, and cognition and sleep disturbances have also found to be associated with the constant use of mobile phones. Although diagnostic and statistical manual (DSM) 5 does not include any criteria for problematic use of technology, a study in 2016, based on the core symptoms of substance use disorders, gives the following as proposed diagnostic criteria for smartphone addiction.

Global health today is facing a major challenge in the form of addictions. Mobile phones, as a telecommunication device, are highly capable of increasing the diversity of information and entertainments available to individuals and organisations around the world. Nowadays, with the emergence of new technologies in the field of Information and Communications Technology (ICT), a myriad of problems related to communication and information have been resolved, the path to reaching the latest news and information in the shortest time is now available, and cyberspace has created new frontiers in social communication.

One of these technologies is mobile phones, which is a rapidly growing phenomenon in the world, so that the number of its subscribers in some countries has exceeded their populations. At the same time, more and more epidemiological studies indicate an increasing connection between mobile phone use and brain tumors in humans. The time length of cancer development after cellular damage may be many years depending on the animal and the type of cancer.

 Aim of this European multicenter case-control study was to assess the association between the incidence of seven types of rare cancers (small bowel carcinoid tumour, uveal melanoma, mycosis fungoides, thymoma, male breast cancer, gallbladder cancer) and occupational exposures. This article presents information about lawsuits against mobile phone industry. The class action lawsuits are starting to pile up against mobile phone industry.

 In August of 2001, a 41-year old Maryland neurologist, Christopher Newman, claimed that his brain tumor was caused by  frequent cell phone usage, and served an $800 million suit against the Cellular Telecommunications and Internet. The intensive use of Information and Communication Technologies (ICT) especially occurs in adolescents and youth population. This use can have negative consequences that should be considered.

The aim of this study was to explore the general and problematic uses of the most popular ICTs among adolescents from Alicante (Spain): Internet, mobile phone and video games. Since the International Agency for Research on Cancer recently classified radiofrequency electromagnetic fields, such as those emanating from mobile and cordless phones, as possibly carcinogenic to humans (group 2B), two additional reports relevant to the topic have been published.

 Both articles were new updates of a Danish cohort on mobile phone subscribers and concern the possible association. For years, radiofrequency (RF) and microwave (MW) radiations have been applied in the modern world. The rapidly increasing use of cellular phones called recent attention to the possible health risks of RF/MW exposures. In 2011, a group of international experts organised by IARC (International Agency for Research on Cancer in Lyon) concluded that

RF/MW radiations should be listed as a possible carcinogen. We live in a dense field of electromagnetic radiation today. It is estimated that this field is up to 200 times stronger than it was a 100 years ago. Power lines, radars, transmitters, electrical appliances, mobile phones, televisions, digital watches, CD/radio players, computers and wireless internet all produce electromagnetic fields, and the problem of electromagnetic “pollution” grows further.
