SALT LAKE CITY [SEPT. 28, 2023] – A new national survey from Myriad Genetics Inc., (NASDAQ:MYGN), a leader in genetic testing and precision medicine, revealed that breast density and family health history are two misunderstood breast cancer risk factors.

Of the women surveyed:

  • 48% do not know what breast density is and 50% are unsure if it has anything to do with breast cancer risk
  • Few women feel like they have all the medical information they need from their mother’s side (19%) and father’s side (15%) to better understand their breast cancer risk
  • Nearly a quarter of women reported they don’t talk about health issues in their families as the primary reason they don’t know anything about their mother’s and father’s family medical history

Women with dense breast tissue are up to four times more likely to develop breast cancer compared to women without dense breasts.1 Higher-density tissue can make it more difficult to detect breast masses or cancer during a screening and may require additional imaging tests. The Federal Drug Administration recently updated mammography regulations requiring mammography facilities to notify patients about the density of their breasts by September 2024.
