It's not the first study that finds the lowly aspirin may protect against the deadliest kind of skin cancer, but it is one of the largest.

And it adds to a mounting pile of studies suggesting that cheap, common aspirin lowers the risk of many cancers — of the colon, breast, esophagus, stomach, prostate, bladder and ovary.

We don't know too much about a Nepalese man who's in medical isolation in Texas while being treated for extensively drug-resistant tuberculosis, or XDR-TB, the most difficult-to-treat kind. Health authorities are keen to protect his privacy.

But we do know that he traveled through 13 countries — from South Asia to somewhere in the Persian Gulf to Latin America — before he entered the U.S. illegally from Mexico in late November. He traveled by plane, bus, boat, car and on foot.

A child born with HIV has been cured of the virus, researchers say. Audie Cornish talks to Richard Knox about what was different about this child among the millions who've been treated in the past and what it means for the prospect of an HIV cure in adults.

Scientists believe a little girl born with HIV has been cured of the infection.

She's the first child and only the second person in the world known to have been cured since the virus touched off a global pandemic nearly 32 years ago.

Doctors aren't releasing the child's name, but we know she was born in Mississippi and is now 2 1/2 years old — and healthy. Scientists presented details of the case Sunday at a scientific conference in Atlanta.

There's great enthusiasm among some global health leaders about a bold – some say radical — strategy to prevent pregnant women from transmitting HIV to their newborns.

But skeptics worry that the approach, dubbed Option B+, will pit pregnant women with HIV against others infected with the virus, diverting resources from the broader struggle against the pandemic.

Researchers say more young American women are being diagnosed with advanced breast cancer.

It's a newly recognized trend. The numbers are small, but it's been going on for a generation. And the trend has accelerated in recent years.

Doctors do stuff — tests, procedures, drug regimens and operations. It's what they're trained to do, what they're paid to do and often what they fear not doing.

So it's pretty significant that a broad array of medical specialty groups is issuing an expanding list of don'ts for physicians.

Don Wright got diagnosed with multiple myeloma at what turned out to be the right time. It was 10 years ago, when he was 62.

That was at the beginning of a revolution in treating this once-fearsome blood cell cancer, which strikes around 20,000 Americans every year. The malignancy can literally eat holes in victims' bones, which can snap from the simple act of bending over to pick up a package.

A blue-ribbon panel is urging stronger regulation of pharmaceuticals around the world to combat the growing problem of fake and poor-quality medicines.

The quality problems and fake medicines have affected Americans. Fungal contamination of steroids made by a Massachusetts pharmacy, which sickened more than 700 people and killed 46, is one recent example. Other U.S. patients have received fake cancer drugs and medicines obtained over the Internet with little or no active ingredients.

The painkiller diclofenac isn't very popular in the U.S., but it's by far the most widely used non-steroidal anti-inflammatory drug, or NSAID, in the world.

A slew of studies, though, show diclofenac — sold under the brand names Voltaren, Cambia, Cataflam and Zipsor — is just as likely to cause a heart attack as the discredited painkiller Vioxx (rofecoxib), which was pulled from the U.S. market in 2004.
