The chances of knowing someone who has had or currently has breast cancer are unfortunately high. In fact, in the U.S., the average risk of developing breast cancer is about 13 percent, translating to a 1 in 8 chance, according to the American Cancer Society. Just last week, at 43 years old, actress Olivia Munn shared that she is one of those statistics after using a breast cancer risk calculator. Despite having a “normal” mammogram and testing negative for BRCA gene mutations, she was diagnosed with Luminal B cancer in both breasts and underwent a double mastectomy. In her Instagram post, Munn credits her OB/GYN, Thaïs Aliabadi, MD, for saving her life through early detection using a Breast Cancer Risk Assessment Score.
While the assessment played a crucial role in Munn’s diagnosis, it may not be accurate for everyone. The most commonly used tool in the U.S. is the National Cancer Institute’s Breast Cancer Risk Assessment Tool, which considers various factors like age, family history, and reproductive history. A score greater than 20 percent is considered high, with the average score being 12 percent.
Furthermore, the assessment may not be as accurate for women of color or those with a history of breast cancer or mutated BRCA genes. Inaccuracies may also arise if the tool does not incorporate family history information. Despite a high-risk score, it does not guarantee that one will develop breast cancer, so further evaluation by a healthcare professional is necessary.
It’s important to start screenings early and have regular check-ups, especially if there is a family history of breast cancer. While at-home assessment tools provide valuable information, they should not replace professional medical advice. Early detection and proper care are crucial in overcoming breast cancer, so don’t hesitate to seek medical attention if you have any concerns.
