The two main factors cited by the US National Cancer Institute are the fact that cell phones generate radiation in the form of radio frequency radiation, or radio waves, and the fact that they are now widely used. This will be of major concern even if there is a slight increase in cancer incidence due to mobile phones.
Additional Details Regarding 5G Cell Phone Radiation
People generally believe that the brain and central nervous system, and tumors related to them, are the two areas of concern. Phone(s) are held close to the head, which is why it happens. Another rationale is the fact that certain brain tumors have been linked to exposure to ionizing radiation. Unlike cell phones, this type of radiation has a higher energy level. Naturally, a number of studies have been conducted to determine whether cell phones are harmful to human health.
Cell phones have been found to emit radiation in the radio frequency range of the electromagnetic spectrum. The frequency range between 0.7 and 2.7 GHz is used by phones that operate on second, third and fourth generation networks (2G, 3G and 4G). A frequency range up to 80GHz should be used by fifth generation (5G) mobile phones on the other hand.
Each of these frequency ranges is therefore in the non-ionizing region of the spectrum. This means it has low frequency and low energy. Insufficient to damage our DNA in any way. You can compare it to ionizing radiation, which is emitted by radon, cosmic rays, and X-rays, in addition. DNA damage is a possibility due to these high frequencies and energies. The reason certain genes can mutate is what can make cancer more likely.
Cohort studies and case-control studies are the two main types of epidemiological research that have been conducted, according to the National Cancer Institute. According to all available data, the use of a mobile phone does not increase the risk of developing brain cancer or any other type of cancer in men. In fact, the researchers found that there was no change in the frequency of brain tumors or other central nervous system tumors linked to cell phone use.
