Tumors arising in the brain can be malignant (cancerous) or non-malignant (benign), with life-threatening consequences where the affected person may develop severe symptoms such as seizures, paralysis or loss of memory, speech, vision and other tasks. In India, brain tumors are estimated to occur at a rate of 5–10 per 100,000 population, however, studies from a few years back have indicated a slight increase in the incidence of brain tumors in recent years, increasing the rate of detection. was believed to be due to the increase in Improved access to medical care and advances in clinical trials are key to a successful outcome since early diagnosis and early treatment of the tumor.
In an interview with HT Lifestyle, Dr. Suresh Sankhla, Neurosurgeon at Global Hospital in Parel Mumbai, shared, “The exact cause of tumor origin remains essentially unknown in most of the cases. However, there is now enough evidence to suggest this. that radiation exposure can cause brain tumors by directly damaging DNA. For the past few years, there has been a growing belief and concern among the general public that the radiation emitted by these devices from cell phone use or overuse results in brain tumors It has also been misreported that cell phones can adversely affect mental health, sleep and normal brain activity leading to the development of brain tumours.”
Although long-term studies are ongoing, to date there is no strong scientific evidence that cell phone use increases the risk of cancer. They revealed, “Cell phones emit radiation in the radiofrequency region of the electromagnetic spectrum. Second-, third- and fourth-generation (2G, 3G, 4G) cell phones emit radiofrequency in the frequency range of 0.7–2.7 GHz and Fifth generation phones (5G) are expected to use a frequency spectrum up to 80 GHz.. These frequencies are classified in the non-ionizing category of the spectrum, which is low frequency and low energy, to damage DNA On the other hand, ionizing radiation, which includes X-rays, radon, and cosmic rays, is high-frequency and high-energy radiation that can damage DNA more easily.
In a study a few years ago, no association or link was found between cell phone use and brain tumors in 420,000 users over a period of 20 years or more. Another interview-based case–control study in 5117 individuals who had brain tumors and a matched control study conducted in 13 countries using a common protocol found no increase in brain or central nervous system tumors related to high cell phone use. Suggested no increase. The Danish cohort study, conducted in 358,000 cell phone customers over 13 years, showed no association between cell phone use and the incidence of brain tumors.
Currently, there is limited evidence that cell phone radiation is a cancer-causing agent and the results of several other ongoing research studies are still awaited. As a result, the International Agency for Research on Cancer, which is part of the World Health Organization, has classified radiofrequency electromagnetic fields as potentially carcinogenic in humans. Dr Suresh Sankhla stressed, “If you are concerned about a possible link between mobile phones and brain tumors, consider limiting cell phone use, or using speakers or speakers to keep the phone away from your head. Use a hands-free device. The only consistent biological effect of radiofrequency recognized in humans is to warm the area of the body where a phone device is (ears and head). The heating is of a low degree and increases the core body temperature. is not enough.”
According to Dr Mazhar Abbas Turabi, Consultant Neurosurgeon at Masina Hospital, Mumbai, “Cell phones emit non-ionizing radiation which is low frequency and low energy. This energy is too low to damage DNA. In 2011, The WHO International Agency for Research on Cancer classified radiofrequency electromagnetic fields from mobile phones as Group 2B, a potential human carcinogen. Three large epidemiological studies have examined the possible association between cell phone use and cancer: The Interphone Study; The Danish Study and the Million Women Study.”
He said, “These studies have been reviewed and reported. These studies were not for heavy phone users. The findings of these studies are mixed, but overall, they do not show an association between cell phone use and cancer. Technologies are improving all the time, so that recent generations emit significantly less output power. Nevertheless, given the lack of evidence for heavy users, advising mobile phone users to reduce unnecessary exposure is a good precaution. way.”
