Your core muscles are your body’s foundation, and the plank pose is a great exercise to do to help build core strength—it’s challenging but not complicated. Here’s everything you need to know to plank correctly.

Memory problems and confusion are just the newest in a list of health problems that appear to disproportionately affect LGBT individuals.

Past research has shown that sexual and gender minority groups may be at higher risk for certain health conditions, including cardiovascular disease and mental health disorders such as anxiety and depression. A new study suggests that another condition — dementia — may also be on that list. Findings presented at the 2019 Alzheimer's Association International Conference showed that people who identified as a sexual or gender minority were more likely than other people to report worsening memory or increased confusion over the past year.

It's possible that some of the same underlying factors that affect risk of other diseases are playing a role in these reported cognitive changes as well, says Dr. Ole-Petter R. Hamnvik, an assistant professor of medicine at Harvard Medical School. "Almost any health outcome that you look at, you can find disparities in these groups. It's not just dementia," he says.

Screening symptom-free adults for pancreatic cancer doesn't appear to reduce deaths from the disease, according to a new analysis by the U.S. Preventive Services Task Force (USPSTF). The group advises against recommending screening in this group.

Pancreatic cancer is relatively uncommon, but the prognosis for people who get it is often poor, because it is frequently found at an advanced stage. This has made it the third most common cause of deaths from cancer in the United States. It was hoped that screening for the disease would enable doctors to spot cases earlier, when they might be easier to treat. However, the USPSTF reviewed findings on pancreatic cancer screening in people without symptoms and determined that there is no evidence that screening in this group — or treating cases of pancreatic cancer found on screening tests — reduces deaths from the disease. The task force concluded that the benefits of screening do not outweigh the potential harms.

Could a traumatic experience raise the risk of ovarian cancer? Researchers at the Harvard T.H. Chan School of Public Health and Moffitt Cancer Center found that women who remembered experiencing six or more symptoms of post-traumatic stress disorder (PTSD) had double the risk of later developing ovarian cancer, compared with women who had not reported PTSD symptoms. They were also more likely to develop a more aggressive form of the cancer. The researchers looked at data from more than 50,000 women who participated in the Nurses' Health Study II. Early in the study, women were asked to identify their most stressful life experience and any PTSD symptoms they had experienced following that event. Researchers then looked to see which of the women went on to develop ovarian cancer. The study, published Sept. 5 in Cancer Research, found higher cancer risk persisted even if a woman's PTSD symptoms had occurred decades in the past. Past animal research suggests that stress hormones may spur tumor growth.

For years, the conventional wisdom about dairy is that we should be eating less of it, and when we do have any it should be low-fat or fat-free. But more recent research suggests that some full-fat dairy in our diets could in fact be beneficial, though the type of dairy still matters.

PrEP (pre-exposure prophylaxis) is a daily medication taken to prevent HIV infection. While multiple studies show PrEP is effective, relatively few of those who might benefit are taking it. Will a 10-year initiative to reduce rates of HIV and a new formulation of PrEP help?

Mammograms look for signs of breast cancer. They can also provide information on whether a woman has high breast density, which slightly increases risk for developing breast cancer. Here’s what you need to know and do if you’re notified about this risk factor.

Dyspareunia is a common problem for many postmenopausal women.

Millions of women experience pain before, during, or after sexual intercourse—a condition called dyspareunia (from the Greek dyspareunos, meaning "badly mated"). This condition not only saps sexual desire and enjoyment, it can also strain relationships and erode quality of life in general. For postmenopausal women, dyspareunia may also raise concerns about aging and body image.

Many women suffer in silence and don't seek the help they need, or they have trouble finding a clinician who can diagnose and treat the causes of their pain. That is unfortunate, because treatments are available for many of the problems that underlie this vexing condition.

Q. I've had endometriosis since I was in my 30s. I'm now approaching menopause. Will my symptoms get better or even go away after menopause?

A. Possibly, but not always. Endometriosis is a condition in which tissue that resembles the tissue that lines the uterus, called endometrial tissue, grows in other locations inside the body. Typically, it grows on structures and organs in the pelvis, such as the ovaries, fallopian tubes, bladder, or bowels. When a woman menstruates, this tissue behaves like the lining of the uterus and bleeds. But because this blood has no way to exit the body, it pools inside. This leads to pain, inflammation, and scarring.

Whole grains contain fiber and nutrients that can help your health.

It's a low-carb world, and many people are pushing grains off their plate in an effort to control their waistline. But they may be doing their body a disservice. Whole grains have some unique properties that make them a valuable addition to the diet. Not only do they contain a host of nutrients, such as iron, B vitamins, copper, zinc, and magnesium, but studies have linked diets rich in whole grains to a lower risk of colon cancer, which is a growing health threat for many younger Americans.

"The main benefit of whole cereal grains, such as wheat, oats, and barley, is in the fiber," says Teresa Fung, adjunct professor in the Department of Nutrition at the Harvard T.H. Chan School of Public Health. "Cereal fiber is different from vegetable fiber or bean fiber."
