Q. I've heard that walking could reduce my risk of breast cancer. Is this true?

A. Yes, it's true. Walking is not only a great form of exercise to help keep your heart healthy, it could potentially reduce your risk of breast cancer. One 2013 study, published in Cancer Epidemiology, Biomarkers & Prevention, found that women who walked seven hours a week — an hour a day on average — had a 14% lower chance of getting breast cancer when compared with women who walked three hours a week or less. The benefit was seen even in women who were at higher risk for breast cancer, including those who were overweight or who were taking hormone therapy. It's not clear how walking helps, but experts speculate that physical activity might help keep the body's levels of estrogen and insulin in check. Both of these hormones can fuel breast cancer, so regulating them more effectively could reduce your risk.

For women living with abusive partners, the COVID-19 pandemic has made an already difficult and dangerous situation even worse. And even if a woman had been thinking about leaving an abusive situation or planning to leave, with current restrictions she may not be able to.

Breast pain after menopause can come in many forms

Menopause has come and gone. Why do I still have breast pain?

In most cases, breast pain is a by-product of reproductive life: Like breast swelling, it waxes and wanes during the menstrual cycle, and it's one of the first symptoms of pregnancy. Many women expect breast pain to go away after menopause. When it doesn't, they may fear they have breast cancer. Fortunately, breast pain is rarely a symptom of cancer, regardless of age. Still, that possibility should be considered, along with a number of noncancerous conditions that affect the breasts.

Many women are living with uncomfortable pelvic organ prolapse. Here are your next steps if you're one of them.

One of the most uncomfortable—and awkward—conditions that afflicts women is pelvic organ prolapse. Normally, the pelvic organs—the bladder, uterus, vagina, and rectum—are supported and held in place by a group of muscles and tissues called the pelvic floor. When these muscles weaken over time, the pelvic organs can droop down and bulge out of the vagina.

In addition to the sensation of feeling an uncomfortable bulge in the vagina, you can experience symptoms such as

Research we're watching

Your diet may influence your breast cancer risk. An analysis of 20 studies by researchers from the Harvard T.H. Chan School of Public Health, which was published online April 6, 2020, by the journal Cancer, found that women who ate the most fiber were 8% less likely to go on to develop breast cancer compared with the women who ate the least.

The reduction in breast cancer risk was seen for both premenopausal and postmenopausal breast cancers, as well as different types of breast cancer, including those that were estrogen and progesterone receptor–positive and estrogen and progesterone receptor–negative. Researchers from the Harvard T.H. Chan School of Public Health said that that the reduction may be due to fiber's effect in reducing both blood sugar and estrogen levels in the body.

Stress can raise your risk of developing a substance use disorder. Here's how to get help when you need it.

In recent months, Americans' collective stress level has risen in response to the pandemic and economic fallout. Many people are looking for ways to help themselves feel better. Unfortunately, stress can trigger a number of unhealthy coping strategies — drinking alcohol to excess, bingeing on junk food, engaging in drug use, or other harmful behaviors. If you've ever had a substance use disorder, a bout of significant stress may even put your recovery at risk.

This is likely due to the shift the human brain makes in times of trauma. Instead of focusing on long-term goals, your brain zeroes in on short-term objectives.

There's no easy answer to this question. Rather, women should make the decision based on their individual needs.

Most women don't look forward to their routine mammogram, which can be uncomfortable and stressful. You may wonder: Is there an age when can you dispense with this regular chore? 75, 80, 85?

The truth is that experts haven't determined a magic age when women no longer need breast cancer screening — largely because scientific evidence in this area is lacking, says Dr. Kathryn Rexrode, associate professor of medicine at Harvard Medical School and chief of the Division of Women's Health at Brigham and Women's Hospital. But many experts also agree that continuing mammography might not be the right choice beyond age 75. The real question, they say, is what is the right age for you to stop based on your individual needs? To decide, you need to understand both the potential risks and benefits of breast cancer screening.

Exercise affects your muscles and bones in similar ways. When you work out regularly, your muscles get bigger and stronger. By contrast, if you sit around doing nothing, they get smaller and weaker. The same principle holds true for bones, although the changes are less noticeable.

Not only do muscles and bones both respond to exercise, but the changes in both of them happen in tandem. That’s because muscles and bones work together to make your body move—and for maximum efficiency, muscle and bone strength need to be bal­anced. Consider what would happen if this balance didn’t exist. At one extreme, a weak muscle wouldn’t be able to move a big, strong bone. At the opposite end of the spec­trum, if a muscle were much stron­ger than a bone, it would snap it.
