Lung Scans: Are You a Candidate?

Screening people at high risk for lung cancer saves lives, a large clinical trial published in the New England Journal of Medicine has confirmed. Yet another study found that few of the people in the U.S. for whom the screening is recommended are getting it. Here’s what to consider before you decide to get a scan—or…

What’s the Best Way to Clean Your CPAP Machine?

If you’ve seen ads for devices that use ultraviolet light or ozone gas to disinfect your CPAP (continuous positive airway pressure) machine and its accessories, you may be tempted to buy one. Before you do, consider the warning from the U.S. Food and Drug Administration (FDA) that these devices have not been authorized for this purpose…

Got Sleep Apnea? A Too-Fat Tongue May Be the Cause

Obesity is a major risk factor for obstructive sleep apnea (OSA). Besides loud snoring, OSA is associated with hypertension, heart disease, diabetes, depression, osteoporosis, and increased mortality. Weight loss is effective in reducing OSA symptoms, though how exactly has not been clear. A novel study in the American Journal of Respiratory and Critical Care Medicine has…

Lung CT Scans: Make Sure Screening Benefits Outweigh the Risks

Using computed tomography (CT) to screen for lung cancer saves lives. However, a 2019 study of complication rates, published in JAMA Internal Medicine, underscores the importance of identifying the patients most likely to benefit from screening.

Cardiorespiratory Fitness Linked to Lower Lung Cancer Risk

People with high cardiorespiratory fitness are at markedly reduced risk for developing lung cancer, and if they do develop it, they have a lower mortality rate than their counterparts who are not fit, according to an observational study published in Cancer. The study found that the same was true for colorectal cancer.

Testosterone Replacement May Raise Risk of Lung Blood Clots

Here’s another reason for men to be wary of taking testosterone, especially if it’s not medically indicated: It may increase the risk of rare but life-threatening blood clots, according to a study in JAMA Internal Medicine. The study found that this was true regardless of how the testosterone was administered—gel, patch, or intramuscular injection.

Eating More Fiber and Yogurt Tied to Lower Lung Cancer Risk

Including more fiber and yogurt in your diet may reduce the risk of lung cancer. So suggests an observational study published in October 2019 in JAMA Oncology. Some earlier research has linked dietary fiber to a lower risk of chronic obstructive pulmonary disease (COPD).

What to Do When Your Asthma Medication Is No Longer Covered by Your Insurer

Insurance providers sometimes change the list of drugs they cover. But switching to a new medication can be especially problematic with asthma when your treatment plan designates not only a particular medication, but also the delivery device itself. Here’s advice to help you get the medication that works for you.

Artificial Intelligence Improves CT Scan Accuracy

Although most suspicious masses that computed tomography (CT) scans detect turn out to be benign, all CT-detected masses must be investigated further, either with more imaging tests using radiation or potentially dangerous lung biopsies. A recent study offers hope that artificial intelligence (AI) can improve the accuracy of CT scans for lung cancer screening, reducing the…

Long Lasting, Progressive Lung Damage Seen in Light and Ex-Smokers

Smoking only a few cigarettes a day doesn’t mean you’re safe from declining lung function, according to a 2019 study in Lancet Respiratory Medicine. And while there’s no question that giving up smoking is good for your health, the study found that the respiratory effects of heavy smoking can linger for three decades or more after…
