Breast Cancer Treatment: Could Soy Cure The Disease?
Many US women are not sure if eating soy based food could help them prevent breast cancer. Earlier studies have shown that soy products could help prevent cancer. Soybean-based food are an excellent protein source that is low in calories and saturated fat. On the contrary doctors do not recommend the consumption of soy products for women who are prone to breast cancer called estrogen-receptor-positive breast cancer. Because soybean-based food contain compounds called isoflavones.
In some studies isoflavones are found to be able to mimic the hormone estrogen and develop tumor growth. In an animal study at the Georgetown Lombardi Comprehensive Cancer Center in Washington, D.C., have revealed the reason behind the capability of soy products to prevent and fuel its spread. By giving a set of rats soybean isoflavones throughout their lives, the rats had improved immunity against cancer. The particular one type of soybean isoflavone given to those rats was called genistein.
But for a set of rats that was not given the soybean isoflavone until after developing breast cancer did not have the same immune response to kill cancer cells. Instead, these rats became at a higher risk of developing breast cancer over again. Even after their tumor was removed.
The study may explain why Asian women have five times lower breast cancer risk than the women in the US. Asian women consume high amounts of soybean-based food in their entire life than women in the US. More than 200,000 US women are diagnosed with breast cancer. Most of them have estrogen-receptor-positive breast cancer, a data from the Centers for Disease Control and Prevention. Tamoxifen is one of the most common drug that acts to reduce estrogen's ability to promote cancer growth.
In the animal study, all of the sets of rats were given tamoxifen to kill the cancer. The researchers found that rats that were raised on genistein had seven percent of breast cancer recurrence after the tamoxifen treatment. However, for the rats that was given genistein after the breast cancer development had 33 percent recurrence rate.
It is not clear why genistein has this kind of effect. But it may be related to the body’s immune system being activated by the isoflavone. The immune system may be recognizing it as a nutrient from its longtime consumption, said study senior author Leena Hilakivi-Clarke. According to the Science Daily, researchers suggest that breast cancer patients should consume soybean products after diagnosis, but do not start them without previous consumption of genistein.
According to the Live Science, The research says that consuming soy products are good ways to prevent cancer, and not to cure it. Consuming soy products would be more helpful if women did not develop any form of cancer yet. However, consuming soy products, during breast cancer treatment would not cure the cancer, but rather encourage the development of tumor.
Breast Cancer Pill Could Reduce The Risk Of Disease
The breast cancer pill is known to reduce the risk of developing disease for women who are at high risk due to family history. However, General Practitioners are not confident in prescribing this drug because it is not licensed as a preventive drug.
Women with Thick Breasts Are More Prone To Having Breast Cancer
Women’s breasts are composed entirely of fat and glandular tissues, but it has now emerged that those with less fat and more tissues could be prone to breast cancer risks – even in the absence of other known risk factors such as family history, having babies after age 30, and genetic mutations among others.

Just because men don't have enlarged breasts doesn't mean they can't have breast cancer. A father becomes the youngest male to undergo double breast removal surgery after both his father and uncle died of the disease.
Breast Cancer Patients Are Not Getting Genetic Testing & Counselling, Doctors 'Never Recommend' It
United States Preventive Services Task Force has emphasized the importance of genetic testing, especially for women with a history of breast cancer in the family. However, a recent study shows only a few actually get their genes tested.
Cancer Rates In Women Set To Rise In The Next 20 Years
A new study predicts the that cancer rates in women will rise six times faster than men. Highlighted as reason for the increased risks are obesity, smoking, and drinking as more women practice unhealthy lifestyles.
Breast Cancer Could Degrade Patient's Healthy Bones
Once the breast cancer spreads throughout the body, it can degrade the patient’s healthy bones and cause more problem. Scientist in the University of Utah discovered that the bones can be destroyed by cancer. They also discovered a new drug that could prevent this from happening. Initial test given to patients show promising results.
