Patients with bile duct cancer might soon have an additional treatment available to them, thanks to a newly discovered tumor target.

Some bile duct cancers are driven by a mutated HER2 gene, which has also been implicated in cancers of the breast, esophagus and prostate, researchers report in a new study.

An experimental drug targeting HER2 mutations, zanidatamab, produced powerful ...

Microplastic pollution is altering the gut microbiomes of wild seabirds and that could be a warning sign for humans, researchers report.

Scientists from McGill University in Montreal, along with colleagues from around the world, found that tiny bits of plastic present in the gastrointestinal system of seabirds have modified the gut's microbiome. The plastics are also reducing levels of ad...

The U.S. Food and Drug Administration on Wednesday approved the first pill form of fecal microbiota -- similar to what's known as fecal transplant therapy -- to treat the bacterial infection Clostridioides difficile, one of the most common and deadly infections found in health care settings.

The drug, Vowst, is approved to prevent recurrence of C. difficile in people who...

People are often reminded that they are their own unique person -- and a new study says that's particularly true of the digestive tract.

Dissections of a few dozen deceased individuals revealed striking differences in gastrointestinal anatomy, even among a small group of people.
