Many inherited cases of breast cancer have been associated with mutations in these three genes. Ad Get What Is Brca Testing.
We know about several gene faults that can increase breast cancer risk and there are tests for some of them.
Breast cancer genetic. Currently the most common genetic tests for this disease are the BRCA1 and BRCA2 gene mutations. Most breast cancers are found in women age 55 and older. Ad My Journey some cool poems and stuff and LEARNING and EARNING at HOME.
However the great majority of breast cancer cases are not related to a mutated gene of high penetrance but to genes. A possible genetic contribution to both breast and ovarian cancer risk is indicated by the increased incidence of these cancers among women with a family history refer to the Risk Factors for Breast Cancer Risk Factors for Ovarian Cancer and Risk Factors for Endometrial Cancer sections below for more information and by the observation of some families in which multiple family members are affected with breast andor ovarian cancer. Genes that increase the risk of breast cancer.

Normally the BRCA1 and BRCA2 genes protect you from getting certain cancers. Abnormal BRCA1 BRCA2 and PALB2 genes may account for up to 10 of all breast cancers. The breast cancer 1 BRCA1 and breast cancer 2 BRCA2 genes are the genes most commonly affected in hereditary breast and ovarian cancer.
This Breast Cancer Gene Is Less Well Known but Nearly as Dangerous PALB2 is not as well known as BRCA but mutations of the gene can. But as science introduces additional. In most cases of breast cancer these genetic changes are acquired during a persons lifetime and are present only in certain cells in the breast.
The genetic factors known to be involved in breast cancer risk comprise about 30 genes. The function of the BRCA and PALB2 genes is to keep breast cells growing normally and prevent any cancer cell growth. But when these genes contain the mutations that are passed from generation to generation they do not function normally and breast cancer risk increases.
Inheriting certain gene changes About 5 to 10 of breast cancer cases are thought to be hereditary meaning that they result directly from gene. If you have a very strong family history of certain cancers there might be a faulty gene in your family that increases your risk of breast cancer.
