Banning the sale of tobacco to people born between 2006 and 2010 could prevent around 1.2 million deaths from lung cancer by the end of the century, according to a modeling. Smoking is responsible for roughly 85 percent of all cases of lung cancer, the deadliest cancer worldwide, according to the World Health Organization.

If current trends continue, there will be nearly three million lung cancer deaths among people born from 2006 to 2010, said the new study from the WHO's International Agency for Research on Cancer (IARC). But if tobacco sales were banned for these 650 million people, around 1.2 million deaths could be prevented by 2095, estimated the modeling research published in The Lancet Public Health journal.

The study, one of the first studies aiming to assess the impact of a tobacco-free generation, drew on data about cancer cases and deaths from 185 countries. More than 45 percent of lung cancer deaths among men around the world could be prevented, and nearly 31 percent among women, the research found. "This difference is linked to the tobacco industry's gender-targeted marketing over the past few decades," IARC researcher and study co-author Isabelle Soerjomataram said in a statement.

But in some regions -- North America and parts of Europe, Australia and New Zealand -- ending tobacco sales could prevent more deaths among women than men, the modeling suggested. The most lives -- 78 percent -- could be saved among women in western Europe, while the highest rate for .
