Breast cancer

Breast cancer is a common disease  and require best health advice nowadays and its frequency is becoming a terrifying reality: one of eight women is affected at some point in her life by breast cancer? To know more about this cruel disease is to become informed about causes and risk factors.
So what causes breast cancer? Mutations in the DNA, those turn normal breast cells into cancerous ones. Changes in the tumor suppressor genes interfere with their way of working, that is, causing cells to die at the proper time and that may lead to cancer. The reason for most of the DNA changes remains unknown.  
Even if the exact causes of breast cancer are yet to be discovered, the existence of certain risk factors that may contribute to the development of this disease is a verified fact. Numerous studies and research have been conducted upon this matter and revealed a number of risk factors and choices made during one’s life that may increase the possibility of developing breast cancer.
The influence of these factors is not carved in stone. Some women might remain healthy, while others, without being subjected to any risk of getting this disease, do find out they have breast cancer.
There are risk factors that women feel powerless against and risk factors about which women can do something about it.
In the first category, gender is one risk factor that cannot be manipulated in any way. The actual idea of being a woman is enough to be predisposed to breast cancer. Men can also have it, true, but cases of men having breast cancer are much more rare.
Aging is another risk factor, that is, the chance of developing this disease increases as a woman grows older.
Genetics influence the manifest of certain mutations in the genes that normally fight against tumors. The inheritance of changes in genes raises the risk of getting breast cancer.
Close blood relatives that had breast cancer constitute a higher factor of risk and almost double the risk of having this disease.
If cancer already invaded one breast, there is an increased risk of developing cancer in the other breast or in areas of the same one.
Curios is the fact that race has also something to do with the risk of getting breast cancer. White women have a more increased risk of getting breast cancer rather than the other populations of women on the globe.
Non-cancerous breast changes might also affect the possibility of having breast cancer.
The alteration of menstrual periods and menopause slightly increase the risk of having breast cancer. Early periods in life or late menopause define this alteration.
