About 2.8 percent of lung cancer cases in the world is attributed to second-hand smoking, according to an official of the World Health Organization (WHO).

Dr. Jean Marc Olive, WHO country representative, said non-smokers are not exempted from acquiring lung cancer, one of the top causes of deaths in the Philippines and in the world.

“Breathing second-hand smoke or SHS is very dangerous to health. It causes cancer, as well as many serious respiratory and cardiovascular diseases in children and adults, often leading to death,” Olive said during the launching yesterday of the “World No Tobacco Day” on May 31.
