Coffee and Cancer

Drinking coffee does not change a person's risk of being diagnosed with or dying from cancer. The research findings have been published in the International Journal of Epidemiology. The QIMR Berghofer study used cancer data drawn from the UK Biobank cohort for more than 46,000 people who had been diagnosed with most invasive cancer types, including about 7,000 people who died from the disease. The genetic and preference information from the people with cancer was compared to data from more than 270,000 others who had never been diagnosed with cancer.
Senior author and head of QIMR Berghofer's Statistical Genetics Group, Associate Professor Stuart MacGregor, said the study looked at data from more than 300,000 people and showed drinking coffee every day neither reduced nor increased a person's risk of developing any cancer.
Associate Professor MacGregor said, "We also know that a preference for coffee is heritable. Our two-pronged research looked at whether cancer rates differed among people with different levels of self-reported coffee consumption, and whether the same trend was seen when we replaced self-reported consumption with genetic predisposition towards coffee consumption. We found there was no real relationship between how many cups of coffee a person had a day and if they developed any particular cancers."
"The study also ruled out a link between coffee intake and dying from the disease."

In an August 2018 statement, the US Food and Drug Administration said current science indicated that consuming coffee posed no significant risk of cancer.
