Here is a review of the 10 risk factors for breast cancer that can not be controlled, namely:
1. Gender / S*x
Being a woman is the most significant risk factor for developing breast cancer.
Although men can get breast cancer too, but the cells of the breast in women are constantly changing and evolving due to the activity of hormones estrogen and progesterone.
Therefore, women have an increased risk of breast cancer greater than men.
2. age
Increasingly older age is the second biggest risk factor for developing breast cancer. Age 30-39 years, the risk is 1 in 233 people, or approximately 0.43%.
While at the time of a person aged 60 years, the risk shoots up to 1 in 27 people, or nearly 4%.
3. History of Breast Cancer in the Family
If someone has a close family (mother, child, brother, or sister) with breast cancer, or have relatives affected by breast cancer or ovarian cancer, especially when before they were 50 years old, so he has a pretty big risk of getting breast cancer.
4. Personal History of Breast Cancer Exposed
If someone is diagnosed with breast cancer, then the risk will increase.
Neither was affected by cancer in the same breast or the other breast cancer, the risk will be greater than if a person has never experienced it.
5. race
White women the risk is smaller than African American women. Race Asian, Hispanic, and Native Americans have a lower risk of developing breast cancer compared with blacks.
6. Radiation Therapy in Breast
Get radiation therapy in the chest when they were children or young adults as a treatment for other cancers will significantly increase the risk of breast cancer.
Increased risk higher when radiation is given while still in the developmental stage or during adolescence.
7. Changes in Breast Cells
Unusual changes in the breast cells are found in breast biopsy may be a risk factor for breast cancer.
These changes include an overgrowth of cells called hyperplasia or abnormal appearance of the so-called atypical.
8. exposure to Estrogen
The hormone estrogen is a female hormone that stimulates breast cell growth. Exposure to estrogen for a long time without a break can increase the risk of breast cancer.
Some risk factors that estrogen exposure can not be controlled, namely:
a. having periods / menstruation before the age of 12 years.
b. menopause at the advanced age or over 55 years of age.
c. exposure to estrogen from the environment such as hormones or pesticides (eg DDT) in the meat, which can produce substances that mimic estrogen when broken down in the body.
9. Pregnancy and Breastfeeding
Pregnancy and breast-feeding reduces the overall number of menstrual cycles in a woman's life, conditions that are thought to reduce the risk of breast cancer.
Women who have never experienced a full or experiencing pregnancy full term after more than 30 years old have an increased risk of breast cancer.
For women with children, breastfeeding can reduce the risk of breast cancer, especially if they continue to breastfeed within 1.5-2 years.
However, many women choose not to breastfeed for a long time because it was considered impractical.
10. Exposure to diethylstilbestrol (DES)
Women who took the drug diethylstilbestrol (DES), which is used to prevent miscarriage in the 1940s until the 1960s, had a slightly increased risk of breast cancer.
Women whose mothers take the drug diethylstilbestrol during pregnancy may have a higher risk of developing breast cancer.
