Scientists say they may have solved a big medical mystery: why mammograms don't save more lives.

A study involving thousands of breast cancer cases, released Wednesday, concludes that a significant proportion of tumors detected through mammography are not small because they are found early.

Instead, the tumors are small because they are biologically prone to slow growth.

The overdose call comes in to Delray Beach Fire Rescue around 7:30 p.m. on a Friday.

Firefighter-paramedics — they’re trained to do both — jump into action and rush to a nearby hotel. But before they can treat this victim, another call comes in.

Diagnosing attention deficit hyperactivity disorder can be difficult. The symptoms of the disorder, as defined by the Diagnostic and Statistical Manual, or DSM, have changed multiple times.

Even if you know what to look for, many of the symptoms are pretty general, including things like trouble focusing and a tendency to interrupt people. Discerning the difference between people who have a problem and those who are just distracted requires real expertise.

Dr. Mark Sklansky, a self-described germaphobe, can't stop thinking about how quickly microbes can spread.

"If I am at a computer terminal or using a phone or opening a door, I know my hands are now contaminated, and I need to be careful and I need to wash my hands," says Sklansky, a professor of pediatrics at the David Geffen School of Medicine at UCLA.

One in eight Americans — 42 million people — still struggles to get enough to eat. And while that number has been going down recently, hunger appears to be getting worse in some economically distressed areas, especially in rural communities.

Food banks that serve these areas are also feeling the squeeze, as surplus food supplies dwindle but the lines of people seeking help remain long.

Last summer’s wave of local transmission of the Zika virus hasn’t yet bled into 2017 , but officials from Key West to West Palm Beach are gearing up for another round of mosquito control by creating new staff positions, adding more equipment and increasing outreach efforts.

If you have ever noticed an itchy or tingly sensation in your mouth after biting into a raw apple, carrot, banana or any of the fruits and veggies listed here, read on.

People who are allergic to pollen are accustomed to runny eyes and sniffles this time of year. But some seasonal allergy sufferers have it worse: They can develop allergic reactions to common fruits and vegetables.

Common blood tests for lead can give falsely-low results in certain cases, according to a new warning from the Food and Drug Administration.

The tests, manufactured by Magellan Diagnostics, are commonly used in doctors' offices and clinics, and on its website the company calls itself "the most trusted name in lead testing." But the FDA now says that its tests can give inaccurate results when used to test blood drawn from a vein.

When 18-year-old Hannah Vanderkooy feels extremely tired or anxious, she heads to a spacelike capsule for a nap — during school. Like many teens struggling to get good grades and maybe even a college scholarship, Vanderkooy doesn't get enough sleep.

And she's not alone. Various studies indicate that chronically sleepy and stressed-out teenagers might be the new normal among U.S. adolescents who are competing for grades, colleges and, eventually, jobs.

American Indian and Alaska Native families are much more likely to have an infant die suddenly and unexpectedly, and that risk has remained higher than in other ethnic groups since public health efforts were launched to prevent sudden infant death syndrome in the 1990s. African-American babies also face a higher risk, a study finds.

It's official: Coral Gables is the first city in Florida to enact a ban on plastic bags. Retailers are no longer allowed to supply them or they could be fined up to $500. This is just one of the new local government prohibitions on carrying containers.

#fakenews isn't just a U.S. thing. And it isn't just about politics. In India people are putting their health at risk by following spurious advice dispensed on forwards on Whatsapp, the phone-based messaging app.

Casey Raub can easily deadlift over 100 pounds — not thanks to the gym, but from his work as a bartender at ever-packed Brooklyn brunch hotspot Five Leaves. Raub, 35, regularly hoists heavy boxes of liquor and massive buckets of ice for an endless stream of gin gimlets and grapefruit margaritas. Two and a half years ago, he was injured in a cycling accident, and his work routine only compounded his back pain.

Why Taste Buds Dull As We Age

May 5, 2017

Sometimes people develop strange eating habits as they age. For example, Amy Hunt, a stay-at-home mom in Austin, Texas, says her grandfather cultivated some unusual taste preferences in his 80s.

"I remember teasing him because he literally put ketchup or Tabasco sauce on everything," says Hunt. "When we would tease him, he would shrug his shoulders and just say he liked it." But Hunt's father, a retired registered nurse, had a theory: Her grandfather liked strong flavors because of his old age and its effects on taste.

In July 2012, a science reporter for The Washington Post, Brian Vastag, was in Wisconsin visiting his family when a high fever hit. He became instantly bedridden with flu-like symptoms that never went away.

"It didn't feel like anything I'd ever had before. ... The things that distinguished it were the dizziness and the feeling of unreality in the head," Vastag says.
