How to Lower Your Risks of Breast Cancer

How to Lower Your Risks of Breast Cancer

Most likely you’ve seen all the pink things that help bolster awareness of breast cancer, from ribbons to football gloves, t-shirts to socks. It’s impressive to see the outpouring of support for the fight against invasive breast cancer — a disease that will affect about one in eight American women during their lifetimes. About 246,000 new cases of invasive breast cancer will be diagnosed in the U.S. during the year.

One powerful cancer fighting tool for women is something that doesn’t have a color. That something is knowledge about how you can reduce your risks of breast cancer. Although understanding the risks for cancer and controlling them can’t ensure you won’t develop breast cancer, controlling your risks can reduce your chances of developing the disease.

The American Cancer Society lists these known lifestyle-related breast cancer risks:

  • Drinking alcohol. This lifestyle choice also increases the risk of other cancers. The more alcohol a person consumes, the greater the risk of breast cancer. One drink per day results in a very small increase in risk. However, if you have two to five drinks per day, the risk is about one and a half times more than a non-drinker. For health, you’re advised to limit drinking. A drink is considered 12 ounces of regular beer, 5 ounces of wine or 1.5 ounces of 80-proof distilled spirits. If someone in your life needs assistance reducing drinking, professional help is available.
  • Being overweight or obese. The risk of breast cancer is greatest after menopause. Before menopause, most of your body’s estrogen is made by the ovaries. After menopause it’s made by fatty tissue. If you have more fatty tissue, you have more estrogen, and that can increase your chances of getting breast cancer. Another factor that affects breast cancer risk is where your body fat collects. Fat around your waist may boost your risk more than fat around your hips and thighs. Your best plan is to maintain a healthy weight throughout your life.
  • Lack of physical activity. We’re continuing to learn more about the positive effects of exercise. If you’re a couch enthusiast, consider that 75 minutes of brisk walking each week can cut your breast cancer risk by 18 percent. Walk more and reduce your risk more. The American Cancer Society recommends adults get 150 minutes of moderate or 75 minutes of vigorous activity each week. It’s best to spread it throughout the week. Moderate activity makes you breathe like you would on a brisk walk. With vigorous activity, your breathing is faster. Activities such as yoga, stretching and weightlifting are also beneficial for your health. A range of options are available to help you get active.
  • Having no children or having a first child after age 30. If you don’t have children or have them later in life, your risk of breast cancer is slightly higher.
  • Using birth control. Use of oral contraceptives (birth control pills) slightly increases the risk of breast cancer. When the pill is no longer used, the risk returns to normal (or baseline) over time. Women who stopped using oral contraceptives more than 10 years ago appear to have no increased risk. Another form of birth control known as Depo-Provera (depot-medroxyprogesterone acetate or DMPA), a form of progesterone given once every three months, appears to increase risk in current users. However, if past users discontinued DMPA use more than five years ago, their risk for breast cancer returns to normal (or baseline) over that time.
  • Using hormone therapy after menopause. To relieve menopause symptoms (and help prevent osteoporosis – bone thinning), women are sometimes prescribed estrogen and progesterone. This is called combined hormone therapy. This therapy can increase the risk of breast cancer. If this therapy is suggested for you, visit with your health care professional to discuss potential risks and benefits.

The Following are NOT Breast Cancer Risks

Let’s dispel some falsehoods about cancer risks. We have no scientific evidence that links breast cancer risk to:

  • Antiperspirant use.
  • Bras.
  • Induced abortion or miscarriage.
  • Breast implants.

If you have questions about your breast cancer risks, visit with your health care professional.

We continue to learn more about breast cancer all the time. Fatalities from the disease have been dropping since 1989. The biggest drop is in women under age 50. We believe more women are finding breast cancer earlier, and we now have better treatments, thanks to ongoing advances in medical research.

We encourage all women to continue with the mammogram schedule your health care professional recommends.
