Many people are dying everyday from cancer related sickness, it was not so before. In many country, every three deaths one is from cancer and it was not so three years ago. What could have been the cause? Could it have been the effect of fast foods that is available in every nook and cranny or is it that human being are so exposed to radiation and emissions from industries? please, profer solution.
