Olivia Munn, known for her roles in movies like “X-Men: Apocalypse,” recently opened up about her breast cancer diagnosis and how a risk assessment tool played a crucial role in her discovery. In an Instagram post, Munn revealed that her physician, Dr. Thaïs Aliabadi, calculated her breast cancer risk score using an online assessment tool. This assessment revealed that Munn had a lifetime risk of 37% for breast cancer, leading to further evaluations and her eventual diagnosis.
Breast cancer risk assessment tools are statistical models that estimate a woman’s risk of developing breast cancer over a certain period. They typically involve questions about medical history, reproductive history, and family history. While these tools are often used by health professionals, patients can also complete the assessment online.
The two commonly used breast cancer risk assessment models are the Gail Model and the Tyrer-Cuzick Risk Assessment Calculator. The Gail Model is available online and provides estimated five-year and lifetime risks of developing breast cancer compared to the average risk for women of the same age and race in the United States.
Dr. Jennifer Plichta, director of the Breast Risk Assessment Clinic at the Duke Cancer Institute, emphasizes the importance of every woman knowing their risk of breast cancer. She suggests that conversations about breast cancer risk should start around the age of 25. Physicians often conduct informal risk assessments during routine appointments, and if necessary, a formal risk assessment using a mathematical model can be performed.
While online risk assessment tools can initiate discussions about breast cancer risk, it is essential to follow up with a healthcare provider to ensure accurate understanding and interpretation of the results. Dr. Plichta advises discussing the results with a doctor or genetic counselor to address any concerns or misunderstandings.
Dr. Otis Brawley, a professor of oncology and epidemiology at Johns Hopkins University, explains that breast cancer risk assessment tools help identify individuals who may be at higher risk, but they have certain limitations. Factors like race and previous biopsies can affect the accuracy of these tools. Therefore, it is crucial to use them under the guidance of a healthcare professional who can provide nuanced interpretations and address any drawbacks.
Individuals who score high on a breast cancer risk assessment may be recommended for additional evaluations beyond regular mammograms. In Olivia Munn’s case, her risk assessment led to an MRI, ultrasound, and biopsy, which ultimately led to her diagnosis. MRIs are often used in high-risk individuals as they can identify abnormalities in blood vessels associated with cancer.
It’s important to note that breast cancer risk assessment tools may not be as accurate or appropriate for everyone. Individuals with a history of breast cancer or mutations in breast cancer susceptibility genes may require tailored tools specific to their circumstances.
The article also discusses when to screen for breast cancer. The US Preventive Services Task Force suggests that average-risk women should start mammogram screenings at age 40 to reduce the risk of dying from the disease. The American Cancer Society recommends annual breast MRIs and mammograms for women at high risk, starting at age 30.
Having access to a breast cancer risk assessment tool empowers patients by providing them with valuable information about their health risks. Dr. Ruth Oratz, a breast medical oncologist, stresses the importance of being aware of personal health risks, family history, and lifestyle factors that contribute to breast cancer risk. Maintaining a healthy weight, following a balanced diet, limiting alcohol consumption, not smoking, and engaging in regular exercise can help lower the risk of developing breast cancer.
Olivia Munn’s story highlights the significance of breast cancer risk assessment tools in early detection and diagnosis. By utilizing these tools and engaging in conversations with healthcare providers, individuals can take proactive steps towards understanding and managing their breast cancer risk.
