Breast cancer genetic testing benefits women by giving them the information they need to adjust medical and lifestyle choices to best fit their situation. Genetic testing also helps put the mind at ease rather than wondering what their genetic background is.

How is genetic testing for breast cancer done?
Genetic testing for the breast cancer genes is doing via blood testing. Previous counseling is a normal requirement.
Is breast cancer inherited?
Breast cancer can be inherited in some cases, but the majority of breast cancers are not directly inherited from a parent. Instead, they are the result of a combination of genetic, environmental, and lifestyle factors. About 5-10% of breast cancers are thought to be hereditary, meaning they are caused by mutations in certain genes that are passed down through families. The most well-known genes associated with hereditary breast cancer are BRCA1 and BRCA2 (short for breast cancer susceptibility gene 1 and 2). Mutations in these genes significantly increase the risk of developing breast cancer and ovarian cancer in both women and men. Inheriting a mutation in one of these genes does not guarantee that a person will develop breast cancer, but it does increase the risk significantly compared to the general population. It's important to note that not everyone with a BRCA1 or BRCA2 mutation will develop cancer, and not all breast cancers are caused by these mutations. Other genes, such as PALB2, PTEN, TP53, and CHEK2, have also been linked to an increased risk of breast cancer when mutated. It's essential for individuals with a family history of breast cancer or other risk factors to discuss genetic testing and personalized risk assessment with a healthcare provider or genetic counselor. They can help determine if genetic testing is appropriate and provide guidance on screening, risk reduction strategies, and treatment options based on individual risk factors. Additionally, regular breast cancer screening, including mammograms and clinical breast exams, is recommended for all individuals, regardless of family history or genetic risk.
What is the method used to perform breast examination?
The testing method used to perform a breast exam is a mammogram.
What is the benefit of using a bra?
It keeps your breast in position.
When someone punches your breast can you get breast cancer?
No.
What is the genetic basis of cancer?
Some cancers show a genetic predisposition - for example BRCA Mutation a form of breast CA.
Is breast cancer genetic or caused by the environment?
In most cases it is genetic, but there are some people who have a perfectly healthy family but they still get it.
Why is medical screening important for the presence of cancer causing genes?
It is important to get DNA screening for certain types of cancer, because you can determine your risk of getting those cancers, and you can take preventative measure and/or get check-ups more often. Especially for situations such as breast, ovarian, cervical, and colon cancers, you can get genetic testing for those proto-oncogenes at any time for a fairly small fee, now that bioinformatics and genetic testing is more common.
What percentage of breast cancer is down to a genetic fault?
5% of breast cancer is down due to a genetic fault. These genes are passed down through abnormal genes passed from parent to child. An example of this is the BRCA genes.
What is the genetic correlation for breast cancer?
breast cancer is more prevalent in females who had a close relative (mother, sister, maternal aunt, or maternal grandmother) with previous breast cancer.
What causes breast tissue to expand without limits?
Breast tissue is mostly made up of fat cells. Breast size is partly genetic, partly hormonal and partly diet.
What is the benefit of breast reconstruction?
Breast reconstruction, especially if it is begun at the same time as the simple mastectomy, can minimize the sense of loss that women feel when having a breast removed.
