Dr. Opal Lee, known as the Grandmother of Juneteenth, is supporting a new cause. As North Texas prepares for Juneteenth celebrations, she is lending her voice to a landmark study.

The study is focused on Black women's health, an area where Dr. Lee has personal experience as a breast cancer survivor.

Further details about the study and Dr. Lee's involvement are available from local news sources, including NBC 5 Dallas-Fort Worth, as she approaches her 100th birthday and continues her advocacy work.
