When it comes to breast cancer, awareness, prevention and early detection save lives and provide the best possible outcome. Therefore, it is important to understand a central issue related to breast cancer: hereditary risk.

Genetic mutations and when to consider genetic testing. Also, explore possible breast reconstruction options available to high-risk individuals considering prophylactic mastectomy surgery.
Genetic Predisposition To Breast Cancer: Moving From “why Me?” To “what’s Next?”
Breast cancer is associated with genetic mutations, inherited mutations, or mutations that occur throughout a person’s life. About 5% to 10% of breast cancers in women are thought to be due to hereditary or inherited genetic mutations. Inherited mutations are abnormal genes that are passed down from one parent.
Genes, which are supposed to maintain healthy cell growth and repair cell damage. These names represent breast cancer gene one and breast cancer gene two. Hereditary cases of breast cancer are commonly linked to mutations in these two genes.
Genetic mutations pass from one generation to another, genes do not always perform their normal functions. This means that as a woman who carries these abnormal genes, the estimated lifetime risk of developing breast cancer at age 80 can increase from an average of 12% to 72% for
Women with one or both of these mutations are also at increased risk of developing other types of cancer, such as ovarian cancer. Although having these gene mutations does not necessarily mean that you will be diagnosed with breast cancer, it is important to discuss surveillance and risk reduction with an experienced genetic counselor
Hereditary Breast Cancer Risk And Genetic Testing
Genetic mutations are not the only genetic mutations that can lead to an increased risk of breast cancer. Identifying these other genes can also save lives.
Genetic tests give you valuable information about cancer risk. A consultation with a genetic counselor will best guide your decision to go ahead with testing. However, some of the factors that may indicate a risk assessment is appropriate for your situation include:
The genetic mutation can potentially reduce the risk of developing breast cancer by 90 to 95 percent through prophylactic or preventative mastectomy. However, the appropriateness of this approach and the degree of risk reduction depend on the situation.
When considering a prophylactic mastectomy, it is important to work with a team of medical specialists, including a genetic counselor, plastic surgeon, and general breast surgeon, among others, to come up with a comprehensive treatment plan that is best for you. needs.

Dr. Orringer will work with you and her team to discuss a variety of options for post-mastectomy reconstruction if that is the route you choose to take. These options may include expander and implant reconstruction and autologous tissue reconstruction procedures, such as DIEP and GAP flaps. As a double-board certified plastic surgeon, microsurgery-trained fellow, with 30 years of experience in reconstruction, Dr. Orringer considers it a privilege to work with you during this time.
If you are considering a prophylactic mastectomy and breast reconstruction, Dr. Orringer will discuss your individual situation and help you explore possible options for breast reconstruction. Call 310-273-1663 today to schedule your personalized and attentive consultation. We welcome patients in Beverly Hills, Los Angeles, Santa Monica, Hollywood, and Newport Beach in Northern California, as well as nationally and internationally.

Thank you for giving me peace of mind and helping me transform… According to a new study, testing for genetic mutations strongly associated with increased breast risk has increased dramatically among women under the age of 40 who have been diagnosed with breast cancer. .
Breast Cancer Risk In Daughters Of Women With Breast Cancer
Overall, within a year of diagnosis, 87% of women in the Young Women’s Breast Study were tested for mutations
Genes. Mutations in one of these genes increase a woman’s lifetime risk of breasts, a woman’s risk of developing breasts at a young age, and her lifetime ovarian risk.
The percentage of women tested increased gradually over the 7-year study period, from approximately 77% of those diagnosed in 2006 to almost all women in 2013.
The genetic mutation may not only influence a patient’s treatment decisions, but also have implications for members of the patient’s family. That’s why doctors often encourage young women who have been diagnosed with breasts to get tested.
How Hereditary Genetic Testing Results Impact
Mutation testing was low in younger women who had been diagnosed with breasts, between 20% and 25%, Dr. Rosenberg and her colleagues noted. However, the visibility of
The genetic tests themselves and also the revelation of actress Angelina Jolie in May 2013, who underwent a preventive double mastectomy after learning that she had damage
The current study included nearly 900 women diagnosed with breasts aged 40 or younger between August 2006 and December 2013 who were treated at 11 community or academic medical centers.
In the first 2 years of the study, 70-80% of participants were evaluated within a year of diagnosis. That percentage increased dramatically in subsequent years, with all but a few women diagnosed in 2012 and 2013 being tested (96.6% and 95.3%, respectively). About 80% said they received test results within 3 months of diagnosis.
Brca Gene And Prostate Cancer
“Increased public awareness may have made women more likely to raise the issue of genetic risk with their doctors, possibly resulting in more testing,” Dr. Rosenberg said in a news release.
About 30% of women who were tested and had a positive or negative result (some women had an indeterminate result) reported that this affected their treatment. In this group, 86 percent of those with a
The mutation surgically removed both the affected breast and the healthy breast (bilateral mastectomy), instead of removing only the affected breast; 53% also had their ovaries and fallopian tubes removed (salpingo-oophorectomy).
Just over half of the women in this group who did not have a mutation also had a bilateral mastectomy, although only a few had a salpingo-oophorectomy.

Mutation tests, nearly half said it was because they didn’t think they had a mutation or because their doctor thought it unlikely they had a mutation.
Trial among younger women treated in the community setting. For example, nearly all of the study participants had health insurance and all were “treated at centers where comprehensive testing and genetic counseling services are widely available,” they wrote.
The tests would probably be lower, if so. said Lyndsay Harris, M.D., of NCI’s Division of Treatment and Diagnosis. There may also be less awareness of recommendations for
Jeffrey Weitzel, M.D., of the City of Hope Center in Duarte, Calif., and his colleagues noted that they were “encouraged” to see more young women diagnosed with breasts undergo the recommended genetic risk assessment. But the results were not all positive, they continued.
Breast Cancer Signs Run In The Family
“It is disconcerting that 48% of those who did not take the test indicated that they and/or their doctor did not think about
Carriers of the mutation,” she said. So it begs the question of whether there is any bias in the way women are informed about their options.”
Mutations undergoing bilateral mastectomy “may also suggest a need for better communication about the relatively low risk of contralateral breast among women who are not carriers…and that bilateral mastectomy is not associated with better survival” .
Women diagnosed with breasts are also expanding the use of other genetic tests, Dr. Weitzel and his colleagues wrote. Next-generation sequencing “ushered in a new era” of genetic alteration testing aside

Some of the women in this study may have had a genetic alteration identified by one of these multigene tests, such as a mutation in the
But “many of the low- and moderate-penetrating genes currently included in multigene panels do not reach a level of risk that justifies” the procedure, they cautioned.

Many of us have heard of the BRCA1 and BRCA2 genes (short for breast cancer genes 1 and 2), as they are the most well-known genetic links to breast cancer. But did you know that men also have a BRCA gene? In recent years, researchers have been working to better understand the BRCA gene, how a mutation in the BRCA gene might play a role in cancer diagnosis, the similarities between breast cancer and prostate cancer, and how a mutation in the BRCA gene could affect the treatment of prostate cancer.
Understanding genetics, family history, and other risk factors can be helpful in navigating a cancer diagnosis, particularly in breast cancer, ovarian cancer, and prostate cancer.
