An experimental therapy seems to have eradicated cancer in a patient with metastatic breast cancer who had failed every other treatment. The goal is to reliably repeat that success in more people.

Food and Drug Administration advisers found that celecoxib poses no greater risk for heart attacks and strokes than prescription doses of popular pain relievers ibuprofen and naproxen do.

A small study finds promise for using gene therapy to treat patients with beta-thalassemia, a blood condition that can cause severe anemia. The experimental treatment is in early development.

An analysis of mice in the Big Apple finds that many harbor bacteria that can make humans sick if exposed to the animals' droppings. Some of the bacterial strains were resistant to antibiotics.

People who experience a sharp drop in wealth face a much higher risk of dying over the next 20 years, according to a study of more than 8,000 adults in the U.S.

The Food and Drug Administration wants to reduce nicotine in cigarettes to levels so low that millions of smokers will be able to quit and millions more people will never take up the habit.

The FDA approved the first test that people can get without a doctor to see if they carry a genetic mutation that increases their risk for cancer. The test looks for three mutations.

Opioid overdoses increased 30 percent nationwide between 2016 and 2017, with some places showing even more dramatic spikes, according to the Centers for Disease Control and Prevention.

More than a third of patients with cancer of the esophagus responded to experimental treatment in China with the gene-editing technique CRISPR. Several CRISPR studies are underway there.

An advisory panel to the Food and Drug Administration recommends the agency accept Philip Morris' claims that its iQOS device, a cigarette alternative, reduces exposure to harmful chemicals.

A team of researchers has produced two macaque monkey clones using a technique called somatic cell nuclear transfer. It's a first for primates. The advance could hasten research into human diseases.

The flu season started early this year and is already widespread throughout the country and intense in dozens of states. But it's not too late to get that flu shot, officials say.

Fears that this winter would bring a nasty flu season appear to be coming true. Health officials say this year's season started early and it's hitting hard.

The opioid epidemic caused U.S. life expectancy to fall for the second year in a row, marking the first time that has happened since the early 1960s. Death rates also continued to rise.

Success with a new gene-editing technique in mice prone to deafness highlights the potential for using it to prevent a form of inherited hearing loss in humans. But it has many hurdles to overcome.

FDA says homeopathy has grown into a $3 billion industry with treatments being sold for conditions ranging from the common cold to cancer. The agency will prioritize action against unsafe products.

Many marketing claims about the potential benefits of probiotics have raced ahead of the science, say researchers who are now trying to catch up. One NIH study is investigating kids' gut microbes.

After decades of hope and disappointment, doctors have now been able to treat several different types of genetic conditions by giving each patient a healthy version of their defective gene.

An influential Harlem church is trying to help the National Institutes of Health overcome reluctance by some African-Americans to participate in a medical study of 1 million diverse Americans.

Scientists have used CRISPR, a new gene-editing technique, to create pigs that can keep their bodies warmer, burning more fat to produce leaner meat.
