What are my chances of getting breast cancer if my sister has it?
What are my chances of getting breast cancer if my sister has it?
If you’ve had one first-degree female relative (sister, mother, daughter) diagnosed with breast cancer, your risk is doubled. If two first-degree relatives have been diagnosed, your risk is 5 times higher than average.
What is considered family history of breast cancer?
Most women diagnosed with breast cancer don’t have a family history of the disease. About 13-16 percent of women diagnosed have a first-degree female relative (mother, sister or daughter) with breast cancer [148].
Are you more likely to get breast cancer if it runs in your family?
It’s important to note that most women who get breast cancer do not have a family history of the disease. But women who have close blood relatives with breast cancer have a higher risk: Having a first-degree relative (mother, sister, or daughter) with breast cancer almost doubles a woman’s risk.
What is the average age a woman gets breast cancer?
The median age of diagnosis of breast cancer for women in the U.S. is 63 [653]. The median is the middle value of a group of numbers, so about half of women with breast cancer are diagnosed before age 63 and about half are diagnosed after age 63.
Which type of breast cancer is hereditary?
BRCA1 and BRCA2 genetic mutations. Most inherited cases of breast cancer are associated with mutations in two genes: BRCA1 (BReast CAncer gene one) and BRCA2 (BReast CAncer gene two). Everyone has BRCA1 and BRCA2 genes.
How fast does breast cancer spread?
According to the Robert W. Franz Cancer Research Center at Providence Portland Medical Center, breast cancer cells need to divide at least 30 times before they are detectable by physical exam. Each division takes about 1 to 2 months, so a detectable tumor has likely been growing in the body for 2 to 5 years.
How are sisters at risk for breast cancer?
Though sisters of women diagnosed with breast cancer have a lifetime increased risk of disease, the researchers found that the amount of increased risk changed over time. Between ages 20 and 40, sisters of women diagnosed with breast cancer have a nearly 6.5 times higher than average risk of breast cancer.
When to start screening for Sisters of diagnosed women?
Sisters of Diagnosed Women Have Higher Risk Forever. This might mean starting screening before the usual starting age of 40. The study reviewed here found that sisters had the highest risk when they were between ages 20 and 40. Your screening plan might include breast ultrasound and MRI, as well as mammograms.
Who is at higher risk for breast cancer?

Can a family history of breast cancer lead to breast cancer?
In some cases, a strong family history of breast cancer is linked to having an abnormal gene associated with a high risk of breast cancer, such as the BRCA1 or BRCA2 gene. In other cases, an abnormal CHEK2 gene may play a role in developing breast cancer. Steps you can take
