Progressing Our Breast Cancer Research

December 10, 2019


 cancer diagnosis carries a heavy burden, both physically and emotionally, no matter who is on the receiving end. For some women, a cancer diagnosis can carry additional and unique challenges, such as self-image issues, an increased feeling of stigma and questions around the feasibility and safety of fertility. These uniquely arduous factors can be as true of any cancer diagnosed in women as they are of the cancer most commonly diagnosed in women: breast cancer.


An estimated 2.1 million new cases of breast cancer are diagnosed globally each year, making it the most common cancer among women and the second most common cancer in the world. While it’s estimated that 1 in 8 women will develop some type of breast cancer in her lifetime, it can also occur much more rarely in men.

Breast cancer can be almost as diverse as it is prevalent, which means prognoses and survival expectations can vary widely based on type, stage and tumor characteristics, such as hormone receptor (HR) status and HER2 status.

The sheer prevalence of breast cancer can — and should — feel staggering, but the treatment paradigm has come a long way in the last thirty years, and so has our ability to detect breast cancer earlier, when it can be more manageable to treat, or prevent it altogether.

Much of this progress can be attributed to the fact that breast cancer treatment is becoming more personalized as we learn more about the disease. For example, detection of the BRCA1 or BRCA2 gene, the most common breast cancer gene mutations, can indicate a woman’s likelihood to develop breast cancer later in life, flagging the need for early and regular cancer screenings.

These improvements in the ability to detect, prevent and classify breast cancer for a more targeted treatment approach have made an impact on the landscape. In fact, breast cancer incidence rates began decreasing around the year 2000 after increasing for the previous two decades.

While all advances, big and small, should be celebrated when it comes to a disease as pervasive as breast cancer, there is always more to do. Thankfully, there is a seemingly great amount within reach as the field evaluates more personalized approaches to care.

Every one of us can think of someone we know who has been touched by breast cancer in some capacity, so the drive to expand our research in the landscape is very personal. — Dr. Dana Walker

“We are leaders in advancing research and identifying precision treatment options in oncology,” said Dr. Dana Walker MD, MSCE, Oncology Development Team Lead, Bristol Myers Squibb. “As we immerse ourselves in the breast cancer space, we look forward to the prospect of continuing to contribute to innovations and potential treatment options that could positively impact such a large population.”

“BMS has been a pioneer in researching new potential treatment options for breast cancer, including bringing some of the earlier treatments on the market, pre-dating a more recent wave of immunotherapy research in the space. Today, we are eager to build upon that history and to expand our vision of advancing science for patients within the breast cancer landscape,” Dr. Walker added.

“Our team is wholly committed to patients and this is just the beginning for us.”
