Lifestyle Interventions

Maintain a Healthy Weight

Carrying an extra 10 pounds of body fat after age 30 increases the risk of breast cancer by 25%. Fat is metabolically active and the major source of estrone following menopause. Maintain a healthy body weight (BMI less than 24) and avoid eating excessive dietary animal fat (less than 20% of daily calories).

Exercise regularly

Regular exercise reduces insulin resistance and body fat and independently can reduce the risk of breast cancer. Data from the Nurses Health Study has shown that even after a diagnosis of breast cancer, women who exercise have better survival rates.

Avoid Alcohol

Excessive consumption of alcohol is one of the most important risk factors for breast cancer following family history. Drinking more than 3 glasses per week increased the risk of breast cancer by 5-fold in the Nurses Health Study.

Consume plenty of Fruits & Vegetables

Fruits and vegetables are rich in anti-oxidants (vitamin A, C, E and selenium). The more colourful -the better. Anti-oxidants reduce free radical damage to DNA. Cruciferous vegetables contain indole-3-carbinol, which increases the 2/16 ratio by aiding in estrogen metabolism. Consuming at least 3 servings daily of broccoli, nappa cabbage, cauliflower, brussel sprouts, and kale or using a dietary supplement like femMED Breast Health can correct the ratio.

Eat Organic

Industrial pesticides (DDT, lindane) and colorants (Red Dye#3) can bind to estrogen receptors and are linked with breast cancer. Consuming organically grown produce to avoid these pesticides and toxins is recommended. Furthermore, commercial livestock is often treated with hormones that can stimulate the breast. Selecting organic meat and dairy can help avoid these hormones.

Avoid industrial plastics/chemicals

Bisphenol-A (banned in Canada in 2010), polystyrene and other compounds present in plastic food packaging and bottles binds to estrogen receptors and are carcinogenic. Use glass cookware for microwave heating foods. Use hair dyes with caution as some of the chemicals used in hair dyes are known carcinogens. The scalp is more absorbent than the skin and chemicals in hair dyes can bind estrogen receptors. Several studies have shown an increased risk of breast cancer with regular use of hair dyes.

Manage your Stress

Mind-body balance is critical to wellbeing and good health. Constant stress contributes to prolonged high cortisol levels which in turn impairs the function of our immune system. We are dependent on our immune system to detect and eliminate cells damaged by free radicals. It is not uncommon that a woman is diagnosed with breast cancer following a stressful life event such as divorce or death of a loved one. Stress reduction techniques include meditation, moderate exercise, tai chi and yoga and pleasurable activities such as enjoying a massage or bath.

There are many other factors that are emerging as risk factors for breast cancer including exposure to synthetic hormones such as those used in oral contraceptives and in menopause hormone therapy, tobacco smoking, direct trauma or injury to the breast and radiation.

Regular screening for breast cancer enables early detection (not prevention) and has been shown to save lives. It is important to partake in regular screening programs involving mammograms performed every 1-2 years after menopause.

Research suggests that by time breast cancer can be visualized by mammogram it has been developing for over 7 years. For this reason, it is important to utilize additional tools in conjunction with mammography to identify women at increased risk include ultrasound, thermography, evaluation of estrogen metabolism, and ductal lavage or nipple aspirate fluid collection.

While our understanding of the factors that transform healthy breast cells to cancer remains in its infancy, it is clear that much of the risk is amenable to interventions under our control. For too long, the focus of intensive research has been on the detection of breast cancer and not its prevention. Dr. Pearlman believes it is time to shift the focus and welcomes the opportunity to discuss how these recommendations can be used to empower you and protect you.
