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…

Air Pollution Triggers Respiratory Emergencies in All Age Groups

Older adults aren’t the only ones who need to worry about their lungs on smoggy days. Poor air quality can lead to emergency respiratory treatment among people of all ages, especially those with asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and acute respiratory infections, according to investigators from the Centers for Disease Control and Prevention (CDC).

Combo Nicotine-Replacement Therapy Boosts Odds of Quitting Successfully

One form of nicotine-replacement therapy (NRT) works about as well as another, but a recent study found that combining two of these treatments may give you the best chance of kicking the habit.

The Benefits of Home Oxygen Therapy for COPD

Some people with chronic obstructive pulmonary disease (COPD) benefit from home oxygen therapy, which typically enhances sleep and mood, increases mental alertness and stamina, and allows people to carry out their daily activities more efficiently. It may also prevent the development of cor pulmonale, a type of heart disease caused by high blood pressure in the…

7 Tips to Help You Breathe More Easily—and When to Call 911

Most often, chronic or recurrent shortness of breath (dyspnea) signals a problem with your lungs or heart. The American Thoracic Society offers advice to help you control breathlessness, once your doctor has diagnosed the underlying cause. If you experience dyspnea, it’s also important to know when to call 911.
