Does coffee prevent head and neck cancer?

Meta-analysis of past studies suggests positive effect, calculating reduced risk of certain cancers for coffee and tea drinkers

2024-12-30
(Press-News.org) In a new analysis of data from more than a dozen studies, coffee and tea consumption was linked with lower risks of developing head and neck cancers, including cancers of the mouth and throat.

Cancers of the head and neck are the seventh most common forms of cancer worldwide, and rates are rising in low- and middle-income countries. Many studies have assessed whether drinking coffee or tea is associated with head and neck cancer, with inconsistent results.

To provide additional insight, investigators led by the University of Utah’s Huntsman Cancer Institute examined data from 14 studies by different scientists associated with the International Head and Neck Cancer Epidemiology (INHANCE) consortium, a collaboration of research groups around the globe. Study participants completed questionnaires about their prior consumption of caffeinated coffee, decaffeinated coffee, and tea in cups per day/week/month/year.

“While there has been prior research on coffee and tea consumption and reduced risk of cancer, this study highlighted their varying effects with different sub-sites of head and neck cancer, including the observation that even decaffeinated coffee had some positive impact,” said senior author Yuan-Chin Amy Lee, an adjunct associate professor for the Division of Public Health in the university’s Department of Family and Preventive Medicine. “Coffee and tea habits are fairly complex, and these findings support the need for more data and further studies around the impact that coffee and tea can have on reducing cancer risk.”

When investigators pooled information on 9,548 patients with head and neck cancer and 15,783 controls without cancer, they found that compared with non-coffee-drinkers, individuals who drank more than 4 cups of caffeinated coffee daily had 17% lower odds of having head and neck cancer overall, 30% lower odds of having cancer of the oral cavity, and 22% lower odds of having throat cancer. Drinking three to four cups of caffeinated coffee was linked with a 41% lower risk of having hypopharyngeal cancer (a type of cancer at the bottom of the throat).

Drinking decaffeinated coffee was associated with 25% lower odds of oral cavity cancer. Drinking tea was linked with 29% lower odds of hypopharyngeal cancer. Also, drinking one cup or less of tea daily was linked with a 9% lower risk of head and neck cancer overall and a 27% lower risk of hypopharyngeal cancer, but drinking more than one cup was associated with 38% higher odds of laryngeal cancer.

Titled, ““Coffee and Tea Consumption and the Risk of Head and Neck Cancer: An Updated Pooled Analysis in the International Head and Neck Cancer Epidemiology Consortium,” the findings were published by Wiley Dec. 23 online in CANCER, a peer-reviewed journal of the American Cancer Society. Funding came primarily from the National Cancer Institute.

A rising trend of 'murderous verbs' in movies over 50 years

2024-12-30
The amount of murdering and killing in movies has increased overall over the past 50 years, according to a new study that analyzed a massive database of film dialogue.   Researchers used machine learning to search a database of subtitles from more than 160,000 English-language movies produced from 1970 to 2000.  They calculated the amount of dialogue from characters using variations of the words “murder” or “kill” in each of the films.   While the total use of these “murderous verbs” varied widely from year to year, there was a clear increasing trend over the five-decade ...

Brain structure differences are associated with early use of substances among adolescents

2024-12-30
A study of nearly 10,000 adolescents funded by the National Institutes of Health (NIH) has identified distinct differences in the brain structures of those who used substances before age 15 compared to those who did not. Many of these structural brain differences appeared to exist in childhood before any substance use, suggesting they may play a role in the risk of substance use initiation later in life, in tandem with genetic, environmental, and other neurological factors. “This adds to some emerging evidence ...

Preclinical study finds surges in estrogen promote binge drinking in females

2024-12-30
The hormone estrogen regulates binge drinking in females, causing them to “pregame” – consume large quantities of alcohol in the first 30 minutes after it’s offered, according to a preclinical study led by scientists at Weill Cornell Medicine. The study establishes–for what is thought to be the first time–that circulating estrogen increases binge alcohol consumption in females and contributes to known sex differences in this behavior. The findings, published Dec. 30 in the journal Nature Communications, could lead to novel approaches for treating alcohol use disorder. “We know a lot less about what drives alcohol ...

Coming AI economy will sell your decisions before you take them, researchers warn

2024-12-30
The near future could see AI assistants that forecast and influence our decision-making at an early stage, and sell these developing “intentions” in real-time to companies that can meet the need – before we even realise we have made up our minds. This is according to AI ethicists from the University of Cambridge, who say we are at the dawn of a “lucrative yet troubling new marketplace for digital signals of intent”, from buying movie tickets to voting for candidates. They call this the "Intention Economy". Researchers from Cambridge’s Leverhulme Centre for the Future of Intelligence ...
