While cigarette smoking remains the biggest cause of lung cancer, between 15% and 25% of cases globally occur in people who have never smoked. Lung cancer claims more women's lives than breast and ovarian cancer combined. Risk factors among nonsmokers include age, family history, chronic lung conditions, and exposure to secondhand tobacco smoke, radon, diesel fumes, air pollution, and asbestos. People concerned about their risks should discuss it with their doctor, reduce exposure to lung cancer contributors, and get involved in advocacy efforts.

Metformin, a medicine prescribed to treat type 2 diabetes, also has cardiovascular benefits and is used off-label to treat other conditions.

With climate change, rising temperatures are making many regions dry within the US and beyond. The effects of droughts on the planet and our health are complex, and include water shortages, higher risk of disease, changes in habitability, and worse air quality.

New research suggests that people who are hospitalized in an intensive care unit are far less likely to develop pneumonia if their teeth are brushed twice daily. They also need ventilators for less time, are able to leave the ICU more quickly, and are less likely to die in the ICU.

Until recently, many people with asthma used a medicine called Flovent. It has been discontinued by its manufacturer, leaving users with questions about what to substitute and which medicines their insurance will cover.

Some products people use daily have been associated with increased cancer risks. Examples are aspartame, nonstick cookware, mattresses, cleaning products, and personal care products. While evidence is mixed, most consumer products confer low cancer risks, if any. People who are concerned about exposure to these common products should find alternatives. People can also reduce their overall cancer risks by stopping smoking, avoiding alcohol, exercising, and maintaining a healthy weight.
