Breast cancer diagnoses have been increasing, especially in younger women under the age of 50. This rise in early-onset breast cancer is concerning because it often leads to more aggressive forms of the disease, such as triple-negative breast cancer or estrogen receptor-negative breast cancer. These subtypes are challenging to treat, and the outcomes can be worse for younger patients. Additionally, surviving a breast cancer diagnosis at a young age means living with a higher risk of developing new cancer or experiencing a recurrence in the future.
Dr. Jasmine McDonald, an assistant professor of epidemiology at Columbia University, specializes in studying breast cancer and its development across a woman’s life course. She focuses on understanding how exposures during critical periods, such as in utero, puberty, and postpartum, can influence the risk of developing breast cancer.
The rising rates of breast cancer diagnoses are seen globally, with Black women and women of African ancestry facing a higher burden. These women are diagnosed at younger ages, more likely to have aggressive cancer subtypes, and have worse outcomes compared to white women. The disparities in breast cancer outcomes highlight the importance of addressing systemic issues that contribute to these inequalities.
Studying cancer risk is complex because cancer is a disease that develops over time and is influenced by various factors. Dr. McDonald’s research focuses on identifying intermediate markers and risk factors associated with breast cancer, such as environmental exposures to pesticides and personal care products. Understanding these associations can help identify ways to reduce the risk of developing breast cancer.
To address systemic issues related to cancer risk, Dr. McDonald emphasizes the need for federal regulations to reduce exposure to toxic chemicals in everyday products. She recommends choosing less toxic personal care products and household items, especially for children who are more vulnerable to harmful exposures. Making small changes over time, such as avoiding plastic containers for hot foods and selecting cleaner beauty products, can have long-term health benefits.
By raising awareness about the impact of beauty standards and environmental exposures on breast cancer risk, Dr. McDonald aims to empower individuals to make informed choices about their health. It’s essential to prioritize health and well-being by selecting products that are less toxic and taking steps to reduce exposure to harmful chemicals in everyday life. Making small changes can add up to significant improvements in overall health and reduce the risk of developing cancer in the future.
