The possibility of breast cancer
There are many risk factors that could potentially lead to breast cancer in women, and the risk of breast cancer is 1: 8. This means for every 8 women you know who have had cancer in their lifetime. So what is the cause of breast cancer and what can we do to prevent it?
Explanation of breast cancer
Breast cancer occurs when certain cells in the breast tissue divide through uncontrolled growth and destroy the surrounding tissue. Cancer cells can then spread to the lymph glands and other organs where they grow. Are and spread in the same destructive way. This is not a normal development that is necessary for the body to function, in the case of breast tissue; Researchers continue to look for different factors that can affect breast cancer. They feel that things are primarily with DNA or genes that cause cellular factors that normally control growth. It could be a congenital genetic mutation. It can also be caused by age, radiation exposure at an early age, or other lifestyle issues.
Speculation about obesity
There are many causes of breast cancer, but one of the risk factors that has been developed and is even more controversial is obesity. According to the research center, breast cancer can be prevented by 25 to 30 percent. Epidemiologists have also noticed an increase in the number of cancers, but they have speculated that our genes have been essentially the same for decades.
Fat and estrogen hormones
So what does fat do to breast cancer? Later fat cells retain estrogen, so the more fat there is in the breast tissue, the more estrogen there is. It is known that estrogen was fuel for breast cancer, which may increase the risk of some research by 60%. The American Cancer Society recommends 30 minutes of exercise 5 days a week to reduce the risk of cancer. It is also recommended that women maintain or increase muscle mass to reduce the formation of fat cells. As mentioned above, the risk factor remains controversial and is not easy to prove. It should be noted that the risk of breast cancer appears when the weight is increased and then it is supported due to young age. This is most likely due to the fact that weight and menopause can produce nerve fat, which is more hormonally active than sub-fat.
What are the other risk factors for breast cancer?
X women mean increased amounts of estrogen.
* Age - 2/3 breast cancer occurs after the age of 55. About 1/8 of all breast cancers occur in people under 45 years of age.
Genetic factors - Many women believe that they have breast cancer if they have no family. She is unlikely to get it. But the facts show that only 5-10% of people with breast cancer have inherited genetic mutations such as BRCA1 and BRCA2.
· Family history - Having a first-degree relative (mother, sister, and daughter) with breast cancer doubles the risk of breast cancer. An estimated 20-30% of women with breast cancer have a positive family history.
A previous history of breast cancer - the risk of developing breast cancer in another breast and not being considered as developing breast cancer earlier.
Race and race - White women have a higher rate of breast cancer than African American women, but African American women are more likely to die from cancer because they have a more aggressive type of breast cancer. Asian, Hispanic, and Native American women have lower mortality and risk of breast cancer.
* Density of breast tissue - It becomes more difficult to screen, there are more tissue glands and less fat tissue.
Menstruation - The onset of menstruation before the age of 12 and menopause after the age of 55 increases the risk of exposure to breast tissue with a higher hormonal cycle. For this reason, having or not having a baby after the age of 30, and breastfeeding for less than a year can also mean that the breast tissue is exposed to more estrogen and progesterone, which increases the risk.
· Radiation - Breast radiation for other conditions such as lymphoma and certain cancers at an early age.
DES - Women who are given DES during pregnancy and whose daughter has a higher risk of developing breast cancer are more likely to have a gene change the next day.
Controversy over oral contraceptives
There are some lifestyle issues that affect the risk of breast cancer. There is a slightly increased risk for women who have been using oral contraceptives for many years, although this risk decreases when OCP is stopped and steadily decreases.
Controversy over shared HRT
Combined HRT has been shown in studies to slightly increase the risk of breast cancer.
