Nearly four out of every 10 cancer cases could be prevented if people avoided a range of risk factors, including smoking, drinking, air pollution and certain infections, the World Health Organisation said Tuesday. New research published on the eve of World Cancer Day estimated that 38% of all new cancer cases globally in 2022 — 7.1 million — were linked to preventable causes. The large team of researchers, which included the WHO’s International Agency for Research on Cancer, looked at 30 factors that increase the risk of getting cancer. Tobacco was the leading offender, responsible for 15% of all new cancer cases, followed by cancer-causing infections with 10% and drinking alcohol with 3%, according to the study published in the journal Nature Medicine.
