 Hi, I'm Dr. Praveen Ghanagi, consultant neurosurgeon working in Manipal Hospital Old Airport Road. Today I'm going to talk to you about the association between the mobile phones and the brain tumors. There has been a lot of speculation about whether the mobile phone usage for a long term can cause brain tumors or not. I'm going to tell you of the facts based on the research publication published in the journals. So there have been studies done in Australia and the US over a period of 10 to 15 years. They have observed the patients who have had a brain tumors. They have shown that there is not much of association between the mobile usage and the brain tumors. But however, there is another group of studies which have done in the Swedish and Interphone study done in 2010. They have shown that there has been slightly increased trend towards the development of primary brain tumors over a long term usage of the mobile phones. Mobile phones emit non-anising radiations. We all know that. So having said that there is a conflict of reports whether there is a some says there is no increase some says there is increased trend towards the development of primary brain tumors. So what we can take a precaution as a mobile phone usage is concerned. The main thing is like how can we take this thing is certain precautions we need to take it. That is use the mobile for only for short conversations. Suppose you have a long conversations use the wired headphones or and whenever there is no usage of the Wi-Fi switch it off and don't keep the mobile in your close to your body when you are not using it keep it away and especially when you are travelling when the special mobile will switch the signal from one tower to other tower don't keep close to your body especially like in your travelling in a car or a bus keep it away from your body. And there is a based on the various studies the International Agency for Research on Cancer has named the mobile phone radio frequency radiation as possibly human carcinogen. That means it can possibly cause primary brain tumors. So having said that that before the further results come out better to take a precaution better to safe and take preventive measures than suffer with this kind of radiation.
