BRCA Mutations Explained

BRCA1 and BRCA2 gene mutations are specific inherited genetic changes that significantly increase an individual's lifetime risk of developing certain cancers. Dr. Esteban Burchard, MD, clarifies that while these mutations were once thought to be extremely rare, they are now understood to be present in approximately 1% to 2% of the general population. These mutations are considered relatively recent in human evolutionary history and represent a powerful example of how a single genetic variant can have a major impact on health.

Angelina Jolie's Impact on Public Health

The public decision by actress Angelina Jolie to undergo risk-reducing surgeries after learning she carried a BRCA mutation had a monumental impact on public awareness. Dr. Esteban Burchard, MD, praises this as a "very bold statement" that was ultimately good for both her personal health and public health perspective. Dr. Esteban Burchard, MD, notes that people with cancer often feel embarrassed and tend to hide their diagnosis, but Jolie's openness helped destigmatize genetic testing and proactive cancer risk management, encouraging countless others to consider their own family history.

Cancer Risks Beyond Breast Cancer

A critical point emphasized by Dr. Burchard is that BRCA mutations confer a high risk for multiple cancer types, not just breast cancer. Carriers face an elevated risk for ovarian cancer, colon cancer, and uterine cancer. Importantly, Dr. Esteban Burchard, MD, stresses that this is not just a female concern; BRCA mutations are also a very strong risk factor for prostate cancer in men. He advises all his patients, including those with a family history of prostate or colon cancer, to consider BRCA genetic testing due to this wide spectrum of associated risks that affect all relatives and descendants of a carrier.

Overcoming Genetic Testing Barriers

Access to BRCA testing was historically limited because the gene was patented by a single company, Myriad Genetics. Dr. Esteban Burchard, MD, highlights the crucial work of researchers like Dr. Harry Oster in New York and Dr. Bob Nussbaum at UCSF, who contributed to a lawsuit that went to the Supreme Court of the United States. The court's decision to overthrow the patent now means that everyone can get a BRCA genetic test affordably and from multiple providers, removing a significant financial and accessibility barrier for patients seeking this vital information.

DNA Ancestry in Genetic Testing Importance

Dr. Burchard provides a powerful personal anecdote to illustrate why genetic testing must not be limited by outdated notions of race or ethnicity. When his Asian sister-in-law was diagnosed with breast cancer, her insurance initially refused to cover BRCA testing, incorrectly claiming it was "only a European disease." Dr. Esteban Burchard, MD, used his expertise in DNA ancestry to argue that as a Filipina, she likely had European genetic ancestry, and the test was therefore medically necessary. This successful appeal underscores a critical rule: disease-causing mutations can be found in any population, and assumptions based on appearance can lead to missed diagnoses.

The Power of Proactive Health Management

The story of Angelina Jolie is the ultimate example of proactive health management based on genetic knowledge. After her mother died from ovarian cancer and another relative died from breast cancer, she pursued genetic testing. Upon confirming a BRCA mutation, she chose to undergo a bilateral mastectomy and later removed her ovaries and fallopian tubes to drastically reduce her high cancer risk. Dr. Anton Titov, MD, and Dr. Esteban Burchard, MD, discuss how this level of proactive decision-making, supported by a medical second opinion, empowers individuals to take control of their health destiny with personalized, precision medicine strategies.

The Future of Widespread Genetic Testing

Individual cancer risk DNA testing is rapidly becoming common practice in mainstream medicine. As Dr. Esteban Burchard, MD, explains, the falling cost and increased availability of tests like BRCA are paving the way for a new era of preventive healthcare. This shift allows for earlier interventions, more personalized screening schedules, and informed family planning. The conversation between Dr. Anton Titov, MD, and Dr. Esteban Burchard, MD, concludes that understanding one's genetic blueprint is a powerful tool, and as more people have access, we will continue to move away from reactive medicine towards a future of proactive, personalized health management.

Individual cancer risk DNA testing becomes common. Cancer genetic tests are moving into mainstream medicine. Rare cancer mutations are not so rare.

Do rare mutations affect you? Angelina Jolie cancer risks. BRCA gene mutations increase risk for breast cancer, colon cancer, prostate cancer, ovarian cancer, and uterine cancer. BRCA1 gene testing is required if any relative has these cancers.

Dr. Anton Titov, MD: Active management of personal genetic risks by actress Angelina Jolie. Top Genetics and Precision Medicine expert explains why it's important to be aware of genetic risks for cancer. Everyone can carry individual genetic mutations that increase risk of cancer and autoimmune disease.

Video interview with top expert in medical genetics and genetic DNA ancestry. Medical second opinion confirms that ovarian cancer diagnosis is correct and complete. Medical second opinion ensures that genetic DNA ancestry information is included in diagnosis of ovarian cancer.

Dr. Anton Titov, MD: Medical second opinion also helps to choose the best personalized treatment strategy for ovarian cancer. Seek medical second opinion on ovarian cancer and be confident that your precision medicine treatment is the best.

Individual cancer risk genetic testing. Medical second opinion. It was reported around the world. Angelina Jolie underwent radical bilateral mastectomy. She removed her ovaries and fallopian tubes. She learned that she inherited a certain BRCA cancer gene mutation. She had family history of breast and ovarian cancers.

Dr. Anton Titov, MD: Her mother died at a young age from ovarian cancer. One of her relatives died from breast cancer at a relatively young age. Such cancer risk mutations occur in 1% to 2% of the population. Cancer risk mutations are relatively recent mutations. Some of your work indicates this.

Dr. Anton Titov, MD: Please talk about clinically relevant cancer mutations in the genome. Why genetic DNA ancestry tests are important for personalized medicine?

Dr. Esteban Burchard, MD: Angelina Jolie is a perfect example of being proactive. Unfortunately, her mother died from ovarian cancer. Angelina Jolie got some insights into the genetic nature of her cancer risks. She actually made a very bold statement for the world.

Normally, when people get cancer they tend to be embarrassed about it. They hide it. She did something really good for medicine and herself. It was good for public health from the public perspective.

Angelina Jolie knew she was at risk for colon cancer, breast cancer, uterine cancer. But also everyone of her descendants, all her relatives were at risk for prostate cancer too. So I tell all patients that I see. You may have someone who has colon cancer or prostate cancer. Then get BRCA tested.

Even in prostate cancer I tell them to get tested. This is a male only disease. I tell them to get tested as well. Because BRCA mutation is a risk factor for prostate cancer. It is not just a risk factor, it is a very strong risk factor for prostate cancer.

Several points were important about Angelina Jolie BRCA testing. Dr. Harry Oster in New York and Dr. Bob Nussbaum here at UCSF did the research work on BRCA mutations. But BRCA gene was patented by Myriad Genetics.

So Dr. Oster and Dr. Nussbaum won the lawsuit in the Supreme Court of the United States. The court overthrew the BRCA patent. So now everybody can get BRCA genetic test for free. BRCA test is now cheap.

My sister-in-law had breast cancer. She happens to be Asian. I demanded that they test her for BRCA gene. The first response was negative. No, because it's only a European disease. We won't pay for it.

I said this. No, I understand genetics. I understand DNA ancestry. She happens to be Filipina. They have European DNA ancestry in them. Using that argument we were able to get her BRCA mutation tested under the insurance.

Dr. Anton Titov, MD: That's again the implications of DNA ancestry at each individual gene. It includes the genes that carry mutations with specific cancer or other diseases.

Dr. Esteban Burchard, MD: Yes, yes. Individual cancer risk genetic testing. Actor Angelina Jolie as example of how to act when serious genetic health risks are found. BRCA mutations and cancer.
