Here’s one reason why past or current smoking may handicap you if you are battling breast cancer: New research suggests that nicotine promotes the spread of the disease to your lungs. Smoking is known to increase the risk that breast cancer will spread, which lowers the survival rate by one-third at diagnosis. But the role of nicotine in the spread of breast cancer to the lungs has been less clear. To learn more, researchers studied almost 1,100 breast cancer patients. They found that current smokers and former smokers had higher rates of breast cancer spread to the lungs than those who never smoked. In studies of mice, researchers found that nicotine fosters that spread. And this was true even after no exposure to nicotine for 30 days. That suggests there’s an ongoing risk for breast cancer patients who are former smokers, according to the team from Wake Forest School of Medicine in Winston-Salem, N.C. Their findings were published online Jan. 20 in the journal Nature Communications. “Our data shows that nicotine exposure creates an environment in the lungs that is ripe for metastatic growth,” said lead study author Kounosuke Watabe, a professor of cancer biology at Wake Forest. Long-term exposure to nicotine creates an “inflammatory microenvironment” in the lungs. That attracts immune cells called neutrophils, which release a protein that encourages the spread of cancer,… read on > read on >

The new year is the ideal time to focus on your health and one expert has some tips, especially for men, for doing that. According to Dr. Kevin McVary, director of Loyola Medicine Men’s Health Center, in Maywood, Ill., “Men don’t always focus on their health and, in fact, men are less likely to see a doctor or utilize health resources, and wait longer than women to seek care. Often, it’s a man’s spouse or partner who convinces him to see a doctor.” As the COVID-19 pandemic continues, “a focus on health is especially important this year,” McVary said in a Loyola news release. “We know that obesity, heart disease, diabetes and a lack of exercise can lead to poorer COVID-19 outcomes. In addition, some men may have stopped eating healthy during the past year, and/or may be consuming more alcohol due to stress. Others may have a condition or concern that they are not seeking treatment for due to the pandemic,” McVary explained. “And yet, lifestyle choices — exercising, eating healthy, not smoking, limiting alcohol consumption and managing stress — combined with preventive care can keep you healthy this year and throughout your lifetime,” McVary added. “And it’s never too late to start.” McVary offers the following tips: Boost your physical activity. Men should exercise 150 minutes each week. “That sounds like a lot… read on > read on >

The first monthly shots to treat adults with HIV were approved by the U.S. Food and Drug Administration on Thursday. “Currently, the standard of care for patients with HIV includes patients taking daily pills to adequately manage their condition. This approval will allow some patients the option of receiving once-monthly injections in lieu of a daily oral treatment regimen,” said Dr. John Farley, director of the Office of Infectious Diseases in the FDA’s Center for Drug Evaluation and Research. “Having this treatment available for some patients provides an alternative for managing this chronic condition,” he added in an agency news release. One expert said the shots will likely be welcomed by HIV patients. The shots “will enhance quality of life” to need treatment just once a month, Dr. Steven Deeks, an HIV specialist at the University of California, San Francisco, told CBS News. “People don’t want those daily reminders that they’re HIV-infected.” Another expert agreed. “Even people who are taking one pill once a day … reported improvement in their quality of life to switch to an injection,” Dr. Judith Currier, an HIV specialist at the University of California, Los Angeles, told CBS News. She consults for ViiV Healthcare, the company behind the long-acting treatment, and wrote a commentary accompanying one study of the drug published recently in the New England Journal of Medicine.

Not many people have had the opportunity to get the COVID-19 vaccine yet. But while you wait your turn, there are some steps you can take to give the vaccine — whichever brand you get — a boost when it’s available to you. An Ohio State University review of 49 vaccine studies dating back 30 years examined how stress, depression and healthy behaviors, such as exercise, can affect immune response to a vaccine. Although it’s not realistic to entirely transform your health and habits in a few weeks or months, there are some steps everyone can take — even last-minute ones — to make a difference. Those include getting good sleep as well as exercise in the days before and after you get your shot, said the review’s senior author, Janice Kiecolt-Glaser. She is director of Ohio State’s Institute for Behavioral Medicine Research, in Columbus. “There are several things that are really reasonable and relatively easy,” she said. Pandemic-related stress may have set people back when it comes to maintaining the behaviors that keep them healthier, the study authors noted. Recent data from around the world have revealed higher rates of depression and anxiety, more insomnia, increased alcohol sales and more overeating, according to the review. The studies in this review looked at the effects of psychological factors and behaviors on immune response to a… read on > read on >
