Habits Worth a Second Look

Many habits that affect your breast health are easy to overlook because they're part of everyday life. The bra you choose, the way you sit at work, and a glass of wine with dinner all play a part. Some deserve more of your attention than you might expect. Others come with worries you can let go of. 

Bras are one of the most common topics our patients ask about at New York Breast Health. Many women have heard that underwire bras cause breast cancer, but research has found no link. Sleeping in a bra doesn't cause cancer either. It also won't prevent sagging the way many believe, so there's no reason to keep one on if you sleep better without it. Fit is where your attention pays off. When a band rides up your back or straps dig into your shoulders, the strain can show up as neck pain and headaches by the end of the day. Since your size can shift after pregnancy, weight changes, and menopause, a fresh fitting every year or two is worth the trip.

Sleep position is another worry you can set aside. Whether you sleep on your side, back, or stomach, there's no evidence it affects your breast health. The one exception is recovery. After breast surgery, your care team may ask you to sleep on your back for a few weeks while your body heals. 

Posture ties back to bra fit more than most women realize. After a long day at the computer, your shoulders tend to round forward as your chin drifts toward the screen. A bra without enough support adds to the pull on your neck and upper back. Over time your chest muscles tighten while your upper back muscles weaken. Rows, doorway stretches, and a few shoulder rolls during the day can help reverse that pattern. If you've recently had surgery, wait until your care team gives you the go ahead before starting anything new.

Moving your body helps well beyond posture. Regular exercise lowers breast cancer risk because it helps balance your hormones and supports a healthy weight. The American Cancer Society recommends 150 to 300 minutes of moderate activity each week. That could look like a brisk 30 minute walk most days. Whatever you choose, the right sports bra matters. Without good support, breasts move in every direction during a run. That motion can cause soreness and strain the ligaments that help them keep their shape.

Changes in your weight often show up in your breasts, which are made partly of fatty tissue. You may notice a difference in their size and shape as you gain or lose weight. Even how dense they look on a mammogram can shift, which our radiologists keep in mind when reading your images. After menopause, weight takes on a new role. Fat tissue becomes one of the body's main sources of estrogen. That's why a higher weight later in life is linked to higher breast cancer risk.

Estrogen also explains the link between alcohol and breast health. Each daily drink slightly increases your risk by raising estrogen levels in the body. That doesn't mean a glass of wine at a celebration is a problem. What matters more is your weekly total. Trading a few weeknight drinks for sparkling water can make a real difference over time.

Smoking affects breast health in a different way. Nicotine narrows your blood vessels, which limits how much oxygen reaches your tissues. That's why surgeons often ask patients to quit weeks before breast surgery or reconstruction, since poor circulation can slow healing. Smoking is also linked to higher breast cancer risk, especially for women who started young. Quitting helps at any age, it only takes a few weeks for circulation to start to improve.

Sunscreen often stops at the face, but your chest needs it too. The skin there is thinner than on most of your body, which makes it more prone to sun damage than you might expect. Scoop necklines, beach days, and years of sunlight through the car window all add up. Extending your sunscreen down past your collarbone takes only a few extra seconds. On the morning of your mammogram, skip lotion, powder, and deodorant as these products can show up as tiny white specks on your images.

You don't need to change everything at once. Start with the habit that feels most doable. The rest can follow in time. If questions come up along the way, bring them to your next visit at New York Breast Health. We're always happy to answer the small ones.
