Advances in breast cancer research have led to more personalized treatments, based on subtyping and more sophisticated testing. A risk assessment test can predict that some women do not need chemotherapy but will benefit from hormone therapy, and who might benefit more from both treatments.

Research we're watching

Women who use marijuana may have more difficulty getting pregnant than women who don't, according to a study published online Jan. 11, 2021, by the journal Human Reproduction.

The study looked at 1,200 women who were trying to conceive after experiencing either one or two miscarriages. The researchers followed the women for six monthly cycles and tracked those who became pregnant for the duration of their pregnancy. Those who reported using marijuana or hashish in the past 12 months or whose urine samples showed evidence of cannabis were 40% less likely to get pregnant during each monthly cycle than those who didn't use cannabis. Only 42% of the cannabis users became pregnant during the study period, compared with 66% of non-users. There did not, however, appear to be any difference in miscarriage rate between users and non-users. The study authors said that further research is needed to confirm the results.

The best prevention for bone-thinning osteoporosis begins early — during the first two decades of life, when you can most influence your peak bone mass by getting enough calcium and vitamin D and doing bone-strengthening exercise. If you are over age 20, there's no need to be discouraged. It's never too late to adopt bone-preserving habits.

If you are a man younger than 65 or a premenopausal woman, these five strategies can help you shore up bone strength as a hedge against developing osteoporosis.

Cardiovascular problems can conspire to put a damper on sexual enjoyment. Talking to your doctor and your partner can help.

A physical connection with your romantic partner is often an important part of a fulfilling relationship. But when it comes to matters of the heart, the health of your heart matters.

"A satisfying sex life depends on physical health, psychological well-being, and the quality of the relationship," says Dr. Jan Shifren, who directs the Massachusetts General Hospital Midlife Women's Health Center. Heart disease and related conditions can influence all three of those factors in both men and women. Here's a look at the range of those effects and some possible solutions.

Whittle your waist for better health.

You've probably heard that extra pounds around your middle are bad for your heart. But a new study has found that excess weight in your belly — a body shape doctors refer to as central adiposity — may be even worse for women's heart health than men's.

The study, in the March 6 issue of the Journal of the American Heart Association, involved about 500,000 people (55% of them women), ages 40 to 69, in the United Kingdom. The researchers took body measurements of the participants and then kept track of who had heart attacks over the next seven years. During that period, the women who carried more weight around their middles (measured by waist circumference, waist-to-hip ratio, or waist-to-height ratio) had a 10% to 20% greater risk of heart attack than women who were just heavier over all (measured by body mass index, or BMI, a calculation of weight in relation to height).

Preterm birth joins other pregnancy-related conditions as potential heart risk factors.

Preterm birth has long been known to bring health risks for the baby, but it may also bring risks for the mother. A study in the June issue of Hypertension shows that women who gave birth to a baby before 37 weeks of pregnancy were more likely to experience rising blood pressures later on compared to women who delivered closer to term. If they had this pattern, they were also more likely to show signs of coronary artery disease, which is associated with an increased risk of heart attack and stroke.

Because of the unique demands that pregnancy places on a woman's body, it may serve as a stress test for the female heart, says Dr. JoAnn E. Manson, the Michael and Lee Bell Professor of Women's Health at Harvard Medical School. In the May issue, we talked about how other pregnancy-related conditions — gestational diabetes, pre-eclampsia (a type of pregnancy-induced high blood pressure), and other pregnancy-related hypertensive disorders — can raise a woman's risk of developing cardiovascular disease. Preterm birth should now join that list, says Dr. Manson.

While as many as one in 10 American women is affected by endometriosis, it can take years to get a correct diagnosis because the symptoms may mimic other common conditions. And myths about this condition may keep some women from seeking help.

Maybe you're feeling tired and having trouble concentrating — or perhaps you've noticed changes in your hair or weight, or just feel blah. You might easily attribute these issues to other health problems, or to simply getting older. But these symptoms can be signs of a sluggish thyroid.

The thyroid is a butterfly-shaped gland in the neck. It produces the hormones that regulate metabolism. Low levels of thyroid hormone can cause a range of symptoms, including fatigue, constipation, dry skin, brittle nails, hair changes, aches and pains, and feeling down. Untreated, an underactive thyroid (hypothyroidism) can increase the chances of developing high cholesterol, high blood pressure, and heart disease.
