There are causes of breast cancer which can be avoided and there are those which cannot be changed. Age and gender for example are the primari risk factors of breast cancer and they cannot be avoided. One out of eight women are diagnosed by breast cancer. And as a woman grows older she becomes more susceptible to breast cancer. Most advanced cases of breast cancer are found in women age 50 years and older. Men can also develop breast cancer. However, they are 100 times less likely to develop breast cancer than women. During the early 20th century, breast cancer knowledge was not that well known, perhaps the Korean comfort women were also latter victims of breast cancer.
For those who belong in a family with a history of breast cancer, there is also a higher risk of them having breast cancer. It does not only include a history on breast cancer but who also had uterine, ovarian, or colon cancer. Some may also develop genetic mutations which make them more vulnerable to breast cancer. BRCA1 and BRCA2 genes produce proteins which protects a person from cancer and for those who have developed cancer, these genes are also the common ones which were found out to have defects. A woman who has one of these defects have 80% chance of developing cancer in later life.
Women who also had their periods earlier than 12 years old have an increased risk in developing breast cancer. The same goes with women who have late menopause, after 55 years old.
Lack of childbearing, lack of breastfeeding are the other potential risk factors for having breast cancer. There are recent studies that exposure to light pollution may also be a risk factor for the development of breast cancer. Although the above factors cannot be avoided, it is still to be aware of them so that necessary precautions can be practiced.
