Seven Ways to Reduce Breast Cancer Risk
Each year you are asked to participate in runs, galas and many other fundraising efforts on national, provincial and local levels to help raise awareness about breast cancer. These are valuable and important efforts, but what can you do on a personal level to reduce your risk for breast cancer?
Risk factors, symptoms to look for, treatment options, statistics, organizations that can help - there is a lot of information out there and it may seem overwhelming. But, if you take it one step at a time, you will be better prepared to deal with any challenges that come your way. Ultimately, having the best information helps reduce your stress and anxiety levels.
Be aware of your health.
Having a family history of cancer increases your risk of breast cancer. But, even if your family doesn’t have a history of cancer or you don’t know their history, it’s important to be aware of your health. Know your body and watch for signs of cancer. Report any changes to your doctor. Discuss the risks of birth control pills and hormones with your doctor. Breast infections can also affect your cancer risk.
Being overweight or obese, besides being generally unhealthy for you, increases the risk of breast cancer. This is especially true if it occurs later in life, particularly after menopause. A healthy diet with lots of fruits and vegetables can help lower your risk and keep your weight at healthy levels.
Not smoking is one of the best things you can do for your overall health, since smoking lowers your quality of life and increases your risk of heart disease, stroke and at least 15 cancers – including breast cancer. The link between smoking and breast cancer risk is particularly important for premenopausal women.
While moderate drinking can be good for the heart in older adults, even low levels of intake can increase the risk of breast cancer. The more alcohol you drink, the greater your risk of developing breast cancer. Keep alcohol at moderate levels or lower (a drink a day or less).
Exercise is one of the best ways to maintain both your physical and mental health. Regular exercise decreases stress levels, helps maintain a healthy body weight, reduces the chances of heart disease and women who are physically active for at least 30 minutes a day have a lower risk of breast cancer.
Regular mammography exams are the best way to find breast cancer early, sometimes up to three years before it can be felt. Finding cancer earlier means broader treatment options. Women who are screened regularly are less likely to need invasive treatments, have less recurrence and are more likely to survive, if breast cancer is diagnosed. According to the Canadian Breast Cancer Foundation, regular mammography screening has been shown to reduce breast cancer deaths by at least 25 percent.

Some Important Risk Factors for Breast Cancer
There are some breast cancer risk factors that women have no control over, but knowing which ones apply to you can help you understand your risk and what you can do to lower it.

- Older age, especially 60 years or over
- Family history of breast cancer
- First menstrual period before age 12
- Menopause at age 55 or over
- First childbirth after age 35
- No children
- Tall height (5’8” or taller)
