The Biological Fact: What is happening in my cells?

• The Truth: BRCA1 and BRCA2 are not “cancer genes”; they are repair genes. Their job is to fix breaks in your DNA.
• The Mutation: A mutation means the “instruction manual” for these repairs has a typo. Because the repair isn’t perfect, errors in your cells can accumulate over time.
• The Result: This accumulation is what increases the statistical likelihood of a tumor developing, particularly in breast and ovarian tissue.

The Risk Fact: What are the actual percentages?

• Breast Cancer Risk: For the general population, the lifetime risk is about 12%. For BRCA1 carriers, it is up to 72%. For BRCA2 carriers, it is up to 69%.
• Ovarian Cancer Risk: The risk is up to 44% for BRCA1 and 17% for BRCA2, compared to less than 2% in the general population.
• The Context: These numbers are not a diagnosis. They are “risk windows” that allow you to choose a specialized prevention plan that the general population doesn’t typically access.

The Inheritance Fact: Who else needs to know?

• The 50/50 Rule: You have a 50% chance of passing the mutation to each of your children, regardless of their gender.
• The Paternal Line: A common myth is that these mutations only come from the mother’s side. In reality, you are just as likely to inherit a BRCA mutation from your father as from your mother.
• Gender Neutrality: Men who carry the mutation can pass it to their daughters and sons, and they also face increased risks for certain cancers, such as prostate and male breast cancer.

The Prevention Fact: What can I actually do?

• High-Intensity Screening: This involves a specialized rotation of Breast MRIs and mammograms. The goal is “Early Detection,” ensuring that if something is found, it is at its most treatable stage.
• Risk-Reducing Surgery: A bilateral mastectomy can reduce the risk of breast cancer by over 90-95%. Removing the ovaries and fallopian tubes can reduce ovarian cancer risk by nearly 96%.
• Chemoprevention: In some cases, specific medications can be used to lower the risk of hormone-sensitive cancers.

The Lifestyle Fact: Does my daily routine matter?

• The Foundation: While lifestyle doesn’t “fix” the gene, it strengthens the body. Maintaining a healthy weight, limiting alcohol, and staying physically active are proven to support overall cancer prevention.
• The Breastfeeding Factor: For some carriers, breastfeeding for a cumulative year or more has been shown to provide an additional layer of protection against breast cancer.

The Testing Fact: What about my “Negative” result?

• The “True Negative”: If you test negative for a known mutation that runs in your family, your risk drops back to that of the general population (approx. 12%).

The Baseline: A negative result doesn’t mean “zero risk”, it means you have the same risk as any other woman. Regular screening remains a vital part of health for everyone.
