What causes breast cancer in women?
Although the exact what causes breast cancer in women is unclear, we know the major risk factors. However, most women considered at high risk of breast cancer do not understand, while many who have no known risk factors. Among the most important factors are advanced age and family history of breast cancer this is one of what causes breast cancer in women. Slight increase in the risk of a woman had a benign breast lump and increases significantly in women who previously suffered from breast cancer or ovarian cancer.
A woman whose mother, sister or daughter had breast cancer is 3.2 times more likely to develop the disease, particularly if more than one first degree relative is affected. Researchers have identified of what causes breast cancer in women two genes responsible for some cases of familial breast cancer – called BRCA1 and BRCA2. About one in 200 women carry it. Once the genes that predispose women to breast cancer, but it does not guarantee it.
In general, women over 50 are more likely to develop breast cancer than younger women. Black women were more likely than Caucasians to develop breast cancer before menopause. A link between breast cancer and hormones is gradually becoming clearer. The researchers believe that what causes breast cancer in women is exposure to an older female hormone estrogen, the more susceptible it is breast cancer. Estrogen tells cells to divide, most cells divide, the more likely that in some way abnormal, can be cancerous.
Exposure to a woman with estrogen and progesterone rise and fall during his lifetime, influenced by the age of menstruation starts and stops, the average length of menstrual cycle and age at first birth. A woman’s risk of breast cancer increases if you started menstruating before age 12, having a first child at 30, stops menstruating after 55, or have a menstrual cycle shorter or longer than the average 26-29 days. Recent information indicates that the hormones in birth control pills can increase risk that is what causes breast cancer in women. Several studies show that taking hormone replacement therapy after menopause may increase the risk, especially when taken for more than 5 years. Jury still out on this bit though. High dose radiation therapy can also be a factor, but low-dose mammograms pose almost no risk.
The interaction between diet and breast cancer is still under debate. Obesity is a major risk factor, and drinking alcohol regularly – more than two drinks per day – may promote breast cancer. Several studies have shown that women with diets high in fat are more prone to breast cancer. Researchers suspect that if a woman lowers the calories of fat per day – less than 20% -30% – a diet may help protect women from breast cancer.
This is an important factor to remember of what causes breast cancer in women. How we treat our bodies can play an important role in preventing breast cancer. Many things can cause breast cancer, including genetics. We can not prevent breast cancer (at least not yet) to occur, but to understand what may increase the chance of developing breast cancer can create a lifestyle that may reduce our chances of having breast cancer.
