About 1 in every 8 women will develop invasive breast cancer at some point in time affect the people living in a total of about 12%. Although some people also suffer from the risk of breast cancer, the disease of about 100 times more women than men.
The estimated number of new cases of invasive breast cancer diagnosed in women, the United States in 2008 was 182,460. Breast cancer is the second largest women's cancer deaths, second only to lung cancer. About 3 percent of all women struggle with the disease will lose their lives. This means that about one-third of every 35 people who suffer from the risk of breast cancer.
A recent study by the U.S. National Cancer Institute found that Asian American women, including a large number of soybean diet during childhood may reduce the risk of breast cancer. Analysis, including women living in California and Hawaii, who is Chinese, Japanese, and Filipino descent. The report can be found in the journal Cancer Epidemiology, Biomarkers and Prevention.
At a news conference, Regina Ziegler, a senior investigator in the Cancer Epidemiology and Genetics Institute for Cancer Research Division, said, "Historically, the incidence of breast cancer have been times of 6:56 white women than in women in the United States or Japan. However, when Asian women emigrate to the United States, the risk of breast cancer has increased by several generations to reach the United States white women, which means that changes in the factors rather than genetics, is responsible for international differences. "Ziegler believes that accurate environmental and / or lifestyle factors remains elusive, said:" The purpose of our study is to identify them. "
In the study, researchers conducted interviews with 597 Asian-American women who have been diagnosed with breast cancer and 966 healthy women. These mothers were also asked about their own childhood, the daughter of soy consumption whenever possible. The results show that a large number of soy intake in childhood (once a week or more) is linked to 58 percent lower risk of breast cancer, and with a high soy consumption during adolescence and adulthood were found, with 20 to 25 percent risk reduction.
Principal investigator, Dr Larissa Korde, staff clinician in the Clinical Research Institute, said genetic disciplines, "as a result of the impact of soy intake of children can not explain the measures other than Asian living in the child or adult life, early soybean photo may be to protect itself. "
According to a recent study, breast cancer can provide the protection of the isoflavones, the estrogen-like compounds to prevent soybean role of estrogen, and promote the destruction of abnormal cells and reduce inflammation of the body. While the new research findings related to the previous study, Ziegler said, "This is the first study to assess the children's soy intake and subsequent risk of breast cancer, a result which is not enough public health recommendations. "She also added that he said:" The investigation needs to be to promote, through further research. "
It is estimated that 5 to 10 percent of breast cancer cases are due to inherited gene changes, called mutations, from the parent company. Family history is another important factor to be considered to be 20-30 percent of women with breast cancer have a family member who has been diagnosed with the disease. Other factors, increase the risk of the occurrence of breast cancer including the use of alcohol and tobacco, as well as obesity and lack of exercise. In addition, the risk of breast cancer increases with age of about 1 8 women developing invasive breast cancer below the age of 45, about 2 3 invasive breast cancer occurred in women over the age of 55 years of age.
Although there is no known means to ensure that the risk of breast cancer prevention can reduce the disease, to avoid the use of tobacco, restrictions on the use of alcohol, exercise regularly and maintain a healthy weight. Avoid the use of postmenopausal hormone therapy, there is no need to be in favor of women who choose to breast-feeding for several months and can also reduce the risk of breast cancer.
