Surviving breast cancer is an important milestone, but for many women it is only the beginning of a long journey toward protecting their overall health.
As survival rates continue to improve, doctors are discovering that heart disease has become one of the greatest threats facing breast cancer survivors. A new study from Cedars-Sinai has found that social and racial differences may play an important role in determining who is most at risk. The research was published in npj Breast Cancer.
Scientists examined health records from more than 200,000 people diagnosed with early-stage breast cancer through a National Cancer Institute database. Their goal was to learn whether certain patient groups experienced different long-term health outcomes after diagnosis.
One of the clearest findings was that Black breast cancer survivors had a greater chance of developing heart failure than white survivors, even after accounting for differences in treatment and existing illnesses. The study also found that women living in lower-income communities faced a higher risk of heart failure than those living in more affluent areas.
The researchers discovered additional health differences. Black, Hispanic, and American Indian or Alaska Native patients were more likely to have aggressive breast cancers when they were diagnosed. Similar patterns were seen among women living in neighborhoods with lower incomes or lower educational levels.
The findings suggest that medical care after breast cancer should not focus only on preventing the cancer from returning.
Doctors may also need to pay closer attention to heart health, especially for patients who appear to have a greater risk. Regular blood pressure checks, healthy lifestyle advice, and heart imaging or other tests may help detect problems before symptoms appear.
The Cedars-Sinai Cardio-Oncology Research Program was created to better understand how cancer and heart disease affect each other. Researchers hope that studies like this one will eventually lead to better screening guidelines and more personalized follow-up care.
Earlier monitoring may allow doctors to reduce complications, improve quality of life, and help more breast cancer survivors live longer and healthier lives.
This study is important because it included information from more than 200,000 women with early-stage breast cancer, making it much larger than many previous studies. Using a large national database allowed researchers to identify patterns that may not be obvious in smaller studies.
However, because it was an observational study, it cannot prove that race or income directly caused the higher risk of heart failure. Other factors, such as access to healthcare, lifestyle, environmental influences, and differences in treatment over time, may also contribute.
Even so, the findings suggest that healthcare providers should pay closer attention to patients who may face higher risks and consider earlier heart monitoring and preventive care after a breast cancer diagnosis.
