LONDON (AP) -- Experts say about 40 percent of cancers could be prevented if people made some lifestyle changes.
Officials at the International Union Against Cancer recommend that people stop smoking, limit their alcohol consumption, avoid too much sun, and maintain a healthy weight through diet and exercise.
They also suggest getting vaccines targeting cancer-causing infections, saying 21 percent of all cancers are due to infections.
The World Health Organization says cancer is responsible for one out of every eight deaths worldwide -- more than AIDS, tuberculosis and malaria combined.
It warns that without major changes, global cancer deaths will jump from about 7.6 million this year to 17 million in 20 years.
World Cancer Day is today.
