Personal risk is also greater if an immediate family member (mother, sister, or daughter) has had breast cancer, particularly if it was at an early age. Also, women who have had a breast biopsy (removal of breast tissue) that shows certain types of benign disease, such as atypical hyperplasia, are more likely to get breast cancer.
Is breast cancer more common in older or younger women?
The older a woman is, the more likely she is to get breast cancer. Rates of breast cancer are low in women under 40. About 4 percent of women diagnosed with breast cancer in the U.S. are younger than 40 [ 4 ]. Rates begin to increase after age 40 and are highest in women over age 70 (see Figure 2.1 below).

Can breast cancer be passed on to multiple generations?
If you have multiple generations diagnosed with breast cancer on the same side of the family, or if there are several individuals who are first degree relatives to one another, or several family members diagnosed under age 50, the probability increases that there is a breast cancer gene contributing to the cause of this familia l history.

What are the most common mutations associated with breast cancer?
The most common mutations associated with breast cancer are BRCA1 and BRCA2 . If genetic testing indicates that a woman is a carrier of these mutated genes, she is at an increased risk for the development of breast cancer and will typically require more frequent monitoring than other women.

Does obesity cause breast cancer?
With that being said, we do know that obesity plays a significant role in the development of breast cancer and that obese women typically have larger breasts than the average woman 2 . So while this might suggest that big-breasted women are at risk, it appears that weight is more of a factor than actual breast size.
Is breast size a factor in breast cancer?
Breast Size and Body Weight in Relation to Breast Cancer. The simple truth is that there have been no large, peer-reviewed studies that support breast size as a factor in the development of breast cancer. While there has been some research suggesting a link 1 , there have been just as many which have drawn the opposite conclusion.
Does alcohol cause cancer?
As an independent risk factor, alcohol is known to increase the levels of estrogen and other hormones associated with the development of breast cancer. Heavy alcohol use can also directly damage DNA in the cells of breast tissue. 5 Damage like this can cause cells to multiply abnormally and at a heightened rate, giving rise to precancerous and cancerous tumors.
Why are older women more susceptible to breast cancer?
They found that as women age, the cells responsible for maintaining healthy breast tissue stop responding to their immediate surroundings, including mechanical cues that should prompt them to suppress nearby tumors.

What is the origin of breast cancer?
The scientists studied multipotent progenitors, a type of adult stem cell that is believed to be the origin of many breast cancers . Two years ago, LaBarge’s group found that as women age, multipotent progenitors accumulate in breast epithelial tissue. They didn’t know why these cells increase in numbers, but they believed their cellular …
Who led the study of breast cancer?
It was led by Mark LaBarge of Berkeley Lab’s Life Sciences Division, with help from first author Fanny Pelissier and other Berkeley Lab scientists, and researchers from UC Berkeley and Norway’s University of Bergen. The scientists studied multipotent progenitors, a type of adult stem cell that is believed to be the origin of many breast cancers. …
Do older women have more cancerous cells?
They also made more of themselves. That’s bad for a couple of reasons. The majority of cancers diagnosed in older women are luminal, and more multipotent progenitors means more cells that can become cancerous.
What is the most common genetic mutation that causes breast cancer?
The most widely known genetic factor that can lead to breast cancer is a mutation on the BRCA1 or BRCA2 gene , which can also cause ovarian cancer. Everyone has these genes, but only some people have a mutation that can predispose them to certain types of cancer. According to the Centers for Disease Control and Prevention, “about 1 in every 500 women in the United States has a mutation in either her BRCA1 or BRCA2 gene. If either your mother or your father has a BRCA1 or BRCA2 gene mutation, you have a 50 percent chance of having the same gene mutation.”
What percentage of Jews are Ashkenazi?
It’s been estimated that anywhere from 75 percent to 90 percent of American Jews are of Ashkenazi descent. Therefore, if you’re Jewish or of Jewish descent, you might want to consider getting genetic testing and counseling to find out what your risks are for breast and ovarian cancer and other hereditary diseases. Senter says she works with many families and individuals who want to know what their genetic make-up may hold for their future health, and they typically start by taking a three-generation family health history. If you’ve had several family members with breast, ovarian or hereditary colon cancer, it might be worth doing further testing to find out your actual risk.
Can you get cancer from a BRCA1 mutation?
Although having a gene mutation does not mean you‘ll definitely develop cancer during your lifetime, it does increase the chances that you might. The CDC reports that about 50 percent of women with a BRCA1 or BRCA2 gene mutation will develop breast cancer by the time they turn 70. Among the general population, the rate is about 8 percent, so it’s a significantly higher risk.
Do cancers run in families?
The American Cancer Society reports that “some types of cancer run in certain families, but most cancers are not clearly link ed to the genes we inher it from our parents.” And all cancers begin with a gene mutating, which results in abnormal cell growth that proliferates and becomes cancer.
Can BRCA mutations cause cancer?
Senter also points out that mutations on the BRCA genes are not the only ones that can cause cancer, but they are the most common. A full genetic workup would likely reveal any other risk factors you might have based on your ancestry.
