Cancer outbeats heart disease; is the leading cause of death in wealthy countries including India

Researchers suggest that cancer is the leading cause of death in wealthy countries, including India & could become the world's biggest killer within a few decades. As of now, heart disease is leading, accounting for 40% of all deaths. However, this is no longer the case in high-income countries where cancer kills twice as many as heart diseases according to the study findings, which are published in the Lancet Medical Journal.
