If you're having chest pain, your doctor can test you for a heart attack. If you're having hip pain, your doctor could test for osteoarthritis.
But what if you're depressed? Or anxious? Currently there are no physical tests for most disorders that affect the mind. Lab tests like these could transform the field of mental illness. So far efforts to come up with biomarkers for common mental health disorders have proved largely fruitless.
People are often told to take low-dose aspirin to reduce the risk of heart attacks and stroke. But that preventive remedy doesn't work for a lot of people.
Researchers say they've found genetic variations that might be used to identify people who don't respond well to aspirin. If the results prove out, there could soon be a blood test to tell who benefits from aspirin, and who needs to look for other treatments to reduce cardiovascular risk.
That sunscreen you dutifully spray throughout the day could actually get you burned.
We're not talking sunburn. We're talking people bursting into flames because they're wearing sunscreen.
Last year, the Food and Drug Administration recorded five incidents in which people were burned after their sunscreen caught on fire. One person was hurt after lighting a cigarette. Another stood near a citronella candle.
Dr. Linda Smith walks into a room at Providence Alaska Medical Center, ready with a stethoscope and a huge grin. She teases her patient, Dawn Dillard, saying that her spiky hair recently resembled a "faux hawk."
Dillard found out she had uterine cancer a year ago. Her oncologist gave her a year to live. The 57-year-old has beaten those odds, but now her kidneys are failing. After the laughs are over, Smith sits down on the edge of Dillard's bed, leans in, and starts talking about a procedure Dillard will have.
