Amid rising numbers of tobacco smokers in the developing countries, like China and India which serves home to 40% of smokers in the whole world, the World Health Organization foresees cancer to overtake heart disease as the No. 1 killer.
Health experts also see development in the diagnosis of cancer and lower cases of communicable diseases that has troubled the human race ever since.
A survey expects diagnosis of cancer in 2009 to hit the scale of 12 million individuals. Deaths due to cancer are projected to be at 7 million.
By 2030 a conservative estimate forecasts cancer cases to blow up to 27 million on a yearly basis with 17 million deaths. All the projected figures also assume the growth of the world’s population.
