As annoying — and agonizing — as it can be, pain is a common and important signal from your body. It’s a sign that something needs attention, and, once you’ve given it that attention and the pain lessens, its absence is an indication that you’re healing.

An epidemic of chronic diseases continues to grow in the United States; half the population — an estimated 129 million Americans — have lifelong health conditions that need continuous medical attention and limit certain daily activities.

Whether your favorite summer activity is taking a long hike on a trail, catching waves at the beach or having fun at a backyard barbecue, the warmer temperatures generally mean more time spent outdoors in the sun. But because more exposure to sunlight means more exposure to the sun’s ultraviolet A and B rays, you need to take steps to protect yourself from cancer-causing ultraviolet radiation.

In a surgical suite at Barnes-Jewish Hospital, a robotic arm snakes an ultra-thin, ultra-flexible tube through a patient’s airway. Once the tube reaches the lungs, the surgeon operating the device remotely uses a tiny camera to search the area for an abnormal growth, or nodule, that might be cancerous. Once located, a needle pierces the nodule for biopsy.
