Breast Cancer awareness month is here and unless you are living in a bubble, you see pink everywhere. From foods to football, products show their support with pink ribbons plastered on them. I saw a pink oatmeal container at the market and now Monday night football. The entire half time show of the Dolphins-Patriots game honored breast cancer survivors with a huge pink ribbon spread across the football field. I say "great", but let's also concentrate on prevention and not just hope for "a cure".
This article, written by a guest blogger, originated in the NY Times Science section, and shows that living a healthy life style can actually decrease your cancer risk. Chinese Herbs have been used for decades to help with diet, digestion and weight loss. If you struggle with maintaining a normal body weight, consider adding digestive enzymes and Chinese herbs to your daily routine for proper digestion and restful sleep. Sleep rejuvenates your body and provides the vital energy that you may otherwise try to compensate for with extra food. (See this article on how restorative sleep can improve weight loss)

Obesity dramatically increases a woman's risk of developing breast cancer by 50-100%, the risk increasing "the older the woman gets and the longer she remains obese." (1) The reason being is that the abdominal fat cells convert steroid (fat soluble) hormones to estrogen. In the breasts, the additional estrogen created binds to the breast cells, promoting "cell division and potentially tumor growth." (2) Cancer cells are abnormal cell growth: the additional cell division cause the tumor growth. Adipose tissue (fat) contains an enzyme, aromatase, that converts steroid hormones into estrogen. After menopause, the ovaries and pituitary gland are no longer signaling for estrogen production through the monthly menstrual cycle. To compensate, the amount of aromatase in the adipose tissue increases to step up estrogen production. Obese women have higher levels of estrogen production taking place in the body fat of the hips and stomach, which increases during menopause, which raises the risk of tumors developing in the breast.
"Glucose [blood sugar] is the preferred substrate for cancer cells. . . [In a study] mice injected with aggressive mammary [breast] tumors were placed on 3 diets. After 70 days 95% of the mice on the low-sugar diet were alive. Of the mice on the moderate-sugar diet 67% were alive. And only 33% on a high-sugar diet were alive. Also 'moderate' alcohol consumption is associated with elevation in the risk for breast cancer from 50-100%." (3)
Phytoestrogens have a chemical structure similar to estrogen. They bind to the receptor sites on the breasts, preventing the body's estrogen from binding and causing tumor cell growth. The phytoestrogens that bind to the breast cell estrogen receptor sites have a weaker influence on breast cell production, so that it is less likely that tumors will form. Common food sources of phytoestrogens include: soy (tofu, tempeh, miso), flax and raw pumpkin seeds, clover and mung bean sprouts. Avoid powdered soy concentrate, these have caused some to develop Hashimoto's thyroid disease. (4)
Studies have shown that phytoestrogens increase the effectiveness of breast cancer treatments. Borage oil has shown to decrease the growth of breast cancer cells. (5)
Eating an organic diet, and limiting exposure to chemicals, including household cleaners, detergents, pesticides, food packaging (plastics leach into foods, especially when warm foods are put into plastic containers) is also important to reduce cancer risk. Chemicals and pesticides can change the DNA of cells, causing them to mutate into cancer cells. Studies have shown higher levels of pesticides and pollutants in fat and blood of women with breast cancer than in healthy women.
