There are many types of risk factors which can increase the chance of developing breast cancer in women. There are certain factors, which can be controlled such as diet, exercise, alcohol consumption and there are other factors, which cannot be controlled such as age and family history. It is very important to identify the various risk factors to prevent the likelihood of developing breast cancer.
Some of the risk factors which cannot be controlled -
Age: Women who are in the age group of forty to fifty years at a high risk as compared to younger women or women above seventy years. Women who are in this age group should go, at least, one time in the year, for mammogram screening and after seventy year the chance reduces, so mammography can be done once in two years.
Hereditary: A woman who has somebody in blood relation who suffers from the disease has a greater chance of developing the cancer. The genes that cause the tumor are BRCA1 and BRCA2. Genes causing breast cancer is found in certain ethnic groups such as Ashkenazi Jewish group, who belong to the east European region.
History: Women who suffered from the tumor of any one of the breasts sometime in their life should have regular mammogram screening.
Other types of risk factors -
Dense tissues in mammogram test: In mammogram screening, women who have dense tissues should take treatment to reduce the density to reduce chances.
Biopsy: Women, who have abnormal growth of tissues also called atypical hyperplasia that is shown through biopsy, should understand the impact of excess growth of the abnormal cells and take treatment for it.
Radiation: The impact of certain radiation on women can be very dangerous, especially if the radiation therapy is taken on the chest.
Reproductive age: Women who are exposed to high level of estrogen hormone have a high chance of developing breast cancer. Estrogen hormone is found in women during the reproductive age and it can be present in some women after menopause. Women, who are exposed to estrogen at the age of eleven and have a late menopause, are exposed to estrogen for a long duration and it can increase the chance.
Pregnancy: Women who get pregnant after thirty years and women, who never gave birth, are at a greater risk.
Taking hormone therapy: Long term use of combined hormone therapy, which includes estrogen and progestin, can increase the risk.
Weight and height: Women who are obese produce more estrogen because the hormone is formed from the fat deposits. Women who are tall have a greater risk as compared to short women.
Consumption of alcohol: Excessive intake of alcohol can elevate the estrogen level, which is dangerous.
Risk of cancer spread from other parts of the body: If a woman is suffering from tumor in the other parts of the body, it may happen that the tumor spreads to breasts. Women who suffer from cancer of endometrium or ovary or colon are at a high risk.
