Breast cancer risk factors Dr Negin Sedaghat

Breast Cancer Risk Factors – Dr. Negin Sedaghat Speaker: Dr. Negin Sedaghat (Breast & Endocrine Surgeon Macquarie University Health. Biography click here).Overview: Explores individualized breast cancer risk assessment beyond general population averages, distinguishing between absolute risk (e.g., 1 in 7 lifetime risk in New South Wales) and relative risk.Key Takeaways:Validated Risk Calculators: Recommends tools like iPrevent (validated for Australian cohorts, incorporating broad family history and lifestyle) and IBIS / Tyrer-Cuzick (international cohort, focusing on menopausal hormone therapy and density) to stratify patients into average, moderate, or high-risk categories.Family History Criteria: Clarifies that a single relative with breast cancer does not automatically place a patient in a high-risk category; high risk generally requires three or more close blood relatives or specific high-risk features like diagnosis before age 40 or male breast cancer.Menopausal Hormone Therapy (MHT): Highlights that estrogen-only MHT in women post-hysterectomy carries minimal to no increased breast cancer risk, whereas combined MHT carries a slight increased risk (~3 additional cases per 1,000 women over 5 years) that varies by progesterone type (e.g., micronized progesterone).Dynamic Risk Profile: Reminds clinicians that risk changes across a woman's lifespan as modifiable lifestyle factors evolve, requiring review every 3 to 5 years.
