New guidelines aim to screen millions more for lung cancer
Lung cancer kills more Americans than any other malignancy. The latest American Cancer Society (ACS) updated guidelines aim to reduce deaths by considerably expanding the pool of people who seek annual, low-dose CT lung screening scans. Advocates hope the new advice will prompt more people at risk for lung cancer to schedule yearly screening, says […]
Plyometrics: Three explosive exercises even beginners can try
As a kid, I spent many Saturdays romping around my Florida neighborhood imitating Colonel Steve Austin, better known as The Six Million Dollar Man to avid TV watchers in the 1970s. The popular show featured a bionic man — half human and half machine — who could jump from three-story buildings, leap over six-foot-high walls, […]
Winter hiking: Magical or miserable?
By midwinter, our urge to hibernate can start to feel constricting instead of cozy. What better antidote to being cooped up indoors than a bracing hike in the crisp air outdoors? Winter backdrops are stark, serene, and often stunning. With fewer people on the trail, you may spot more creatures out and about. And it’s […]
Icy fingers and toes: Poor circulation or Raynaud’s phenomenon?
If your fingers or toes ever turn pale (or even ghostly white) and go numb when exposed to cold, you might assume you just have poor circulation. That’s what I used to think when I first started noticing this problem with my own hands many years ago. It usually happened near the end of a […]
Which migraine medications are most helpful?
If you suffer from the throbbing, intense pain set off by migraine headaches, you may well wonder which medicines are most likely to offer relief. A recent study suggests a class of drugs called triptans are the most helpful option, with one particular drug rising to the top. The study drew on real-world data gleaned […]
New research shows little risk of infection from prostate biopsies
Infections after a prostate biopsy are rare, but they do occur. Now research shows that fewer than 2% of men develop confirmed infections after prostate biopsy, regardless of the technique used. In the United States, doctors usually thread a biopsy needle through the rectum and then into the prostate gland while watching their progress on […]
Dialectical behavior therapy: What is it and who can it help?
Feeling sad, anxious, or angry at times is a normal part of the human experience. But do you — or someone you’re close to — seem to experience these and similar emotions more quickly, more frequently, and more intensely than most people? This problem, known as emotional dysregulation, is a hallmark of many mental health […]
What is a tongue-tie? What parents need to know
The tongue is secured to the front of the mouth partly by a band of tissue called the lingual frenulum. If the frenulum is short, it can restrict the movement of the tongue. This is commonly called a tongue-tie. Children with a tongue-tie can’t stick their tongue out past their lower lip, or touch their […]
Why do your prescription drugs cost so much?
I was in line at a pharmacy recently as the customer ahead of me was picking up her prescription. The pharmacist matter-of-factly said: “that’ll be $850.” All she could say was “really?” She left without her prescription, telling the pharmacist she’d have to call her doctor about a less costly alternative. Many of us routinely […]
Shining light on night blindness
Animals renowned for their outstanding night vision include owls, cats, tarsiers (a tiny primate in Southeast Asia) — and even the dung beetle. But humans? Not so much. Over time, many people suffer from night blindness, also known as nyctalopia. This condition makes seeing in dim or dark settings difficult because your eyes cannot adjust […]
