Breast cancer is still unknown disease until this day, despite the fact that cancer affects nearly ten percent of women over the age of forty years around the world. Cause this killer cancer is not known even after decades of research. So it is not known why some women have a higher chance to get Breast Cancer than the others.
Various risk factors for breast cancer are as follows:
1. Breast cancer family history
If the brother or sister who was near the mother has breast cancer, then there is a very high likelihood that the cancer will occur sometime in your life. This tendency is observed even if distant relatives, such as cousins and aunt had breast cancer, though likely lower. Even if a brother has cancer of the breast or prostate cancer, then there are chances of getting breast cancer. This clearly shows that breast cancer walks through the family line through inheritance. Of course the possibility is very high if more than one family member has breast cancer.
2. Personal history of breast cancer
If a woman has had breast cancer in the past, then there is a great possibility that breast cancer can occur again. This is true even if the cancer has been removed although in the stage of benign. Sometimes cancer cells spread to adjacent lymph. This makes it likely that the cancer will occur in the another breast. In fact, women who have had breast cancer have 50-75% more chances to develop breast cancer in the another breast.
3. Breast disease
Some breast disease can increase the likelihood of having breast cancer. Changes in breast cells can lead to atypical hyperplasia. This condition may cause a a three-four times the increase in the chances of getting breast cancer the following year. This risk also exists if the atypical hyperplasia has occurred in other women in your family. Other conditions such as benign tumours of the breast is a condition known as fibro adenoma. However, women with fibrocystic breasts generally do not have any vulnerabilities to breast cancer. However, such a condition could make a lump and hide the real of breast tumor (if any) during mammography.
In today's world, the lifestyle is the largest single contributing factor to the development of breast cancer among women. Some elements of lifestyle has been found to be the prevalence of breast cancer. Smoking and alcoholism in women is a major factor. Diet even pointed out as a risk factor that is important. Women who consume foods with higher cholesterol fats in it has a higher chance to hit by breast cancer. At the same time, lifestyle without engaging much in physical activity is also potentially dangerous.
It has been found that women who undergo radiation therapy in their chest area at a young age have an increased risk of developing breast cancer in their life later. Radiation therapy is commonly prescribed to women with conditions such as Hodgkin's disease or non-Hodgkin's lymphoma. So women who have undergone treatment as possible will get breast cancer in later years.
There are several factors which can alter the hormonal balance of the body. A few of them:
- Early menstrual cycle early, i.e. before the age of twelve,
- Because the first pregnancy after the age of thirty years,
- Has a pregnancy does not exist at all
- Have menopause end.
All of these conditions can increase the levels of estrogen in the body. This increases the risk for breast cancer to light levels. In addition to that women who use birth control pills, breast enhancement supplements, antidepressants and antihistamines and hormone supplements have a higher risk for getting breast cancer.
Above is a major risk factor for breast cancer is exposed. But because the studies on breast cancer is not yet complete, the list above is not a complete list. There is some indication of breast cancer, such as breast implant surgery; But this has not been confirmed. Implants used in previous days made of silicone gel. This is risky in terms of breast cancer. However, currently the silicone gel implant is replaced by a saline implants. This has reduced most of the risk.
Should also note also that women have a much higher chance to get breast cancer than men. In fact, most people think that breast cancer is a disease that only affects women. This is not true. Men can also be affected by breast cancer, but for a much lower rate than women. Also, the age is a very important factor. Your risk for getting breast cancer are much higher when the woman has crossed the age of 50 years.
