Alcohol and meat ‘strongly’ linked to stomach cancer

Drinking alcohol, eating processed meat and being overweight have been “strongly” linked to stomach cancer for the first time.

A new study from the World Cancer Research Fund (WCRF) found an increased risk of stomach cancer for people who drink three or more alcoholic drinks a day (equivalent to more than 45g of alcohol per day).

Eating the equivalent of 50g per day of processed meat - two pieces of bacon - was also linked to stomach cancer, while being overweight or obese also increased the risk.

However, eating citrus fruits may decrease the risk, experts said.

Just in excess of 7,000 people are diagnosed with stomach cancer every year in the UK and it leads to about 5,000 deaths.

Most people are diagnosed when their cancer has started to spread across the body.

According to Cancer Research UK, doctors generally think a patient is doing very well if they are still alive two years after being diagnosed with advanced stomach cancer.

Men are twice as likely as women to develop stomach cancer, and it is more common in older adults.

‘Strong evidence’

In the new report, WCRF scientists said there was “strong evidence” that drinking about three or more alcoholic drinks per day increased the risk of stomach cancer, as did being overweight or obese.

They also pointed to “strong evidence” that consuming foods preserved by salting increased the risk, and “strong evidence” that consuming processed meat increased the risk.

The report said: “Processed meat is meat that has been preserved by smoking, curing or salting, or by the addition of preservatives.

“Examples include ham, bacon, pastrami and salami, as well as hot dogs and some sausages.”

Processed meat is already linked to bowel cancer, while being overweight or obese is linked to 10 different cancers.

Dr Rachel Thompson, head of research interpretation at the WCRF, said: "This new evidence gives us a clearer picture.

“We can now say, for the first time, that drinking alcohol, eating processed meat and being overweight or obese can all increase the risk of developing stomach cancers.

“These findings will hopefully help people better understand what increases their risk of cancer so that they can make informed decisions about their lifestyles choices.”

In the UK, the lifetime risk of stomach cancer stands at one in 67 for men and one in 135 for women.

WCRF experts believe more than 1,200 cases of stomach cancer in the UK could be prevented each year if people did not drink three alcoholic drinks per day, cut out processed meat and were a healthy weight.
