Oncology
BMS is a pioneer in advancing innovative cancer therapies, dedicated to improving patient outcomes and enhancing their quality of life.
Stronger together for cancer patients
Cancer is a disease caused by the uncontrolled division of cells in the body. These cells multiply, invade surrounding tissues, and sometimes spread to other parts of the body. Cancer can develop in almost any organ or tissue, with over 100 different types. Despite their differences, all cancers share the common feature of uncontrolled cell growth. The rate at which this happens varies, which is why some cancers cause symptoms more quickly than others.
Cancer prevalence in Belgium
In 2022, a total of 474,411 individuals were living with cancer in Belgium, having been diagnosed between 2013 and 2022. This corresponds to approximately 4% of the country's population1. Among men, prostate cancer was the most prevalent, with 77,930 cases (1.4% of the male population), while among women, breast cancer was the most common, with 89,039 cases (1.5% of the female population). For both sexes, lung and colorectal cancers were the second and third most common.
While cancer prevalence reflects the number of people living with a previous diagnosis, it is influenced both by the number of new cases (incidence) per year and by patient survival over time. In 2022 alone, 76,220 Belgians received a new cancer diagnosis2. Beyond the incidence figures, improvements in cancer survival have played a major role in the growing number of people living with cancer. For patients diagnosed between 2016 and 2020, five-year relative survival rates in Belgium reached 98.4% for prostate cancer, 92.4% for breast cancer, 71.1% for colorectal cancer, 68.8% for cervical cancer, and 25.9% for lung cancer3. These outcomes reflect significant advances in early detection, innovative treatments, and patient care.
What are we doing in the field of oncology?
For over fifty years, Bristol Myers Squibb has been committed to discovering, developing, and delivering innovative cancer treatments to improve patient care and help people live longer and better lives.
We collaborate closely with scientists, healthcare professionals, governments, and patient organizations, continuously exchanging insights and experiences to foster innovation in cancer care and improve patient outcomes.
We empower our employees to explore, refine, and realize their ideas with partners who share our determination to beat cancer.
In support of the broader oncology community, we also sponsor symposia, congresses, and events organized by organizations such as the Belgian Society of Medical Oncology (BSMO), which covers multiple cancer types, including skin, lung, renal, urothelial, head and neck, and gastrointestinal cancers.
In oncology, we focus on three pillars
Melanoma: More than a decade of progress in treatment options
Among the various cancer types, melanoma stands out as the most severe form of skin cancer and the fifth most common cancer in Belgium. Its incidence has been rising steadily, particularly among individuals aged 45 and older, making it an increasing public health concern4. By 2040, the number of melanoma cases in Belgium is projected to rise by over 11%, underscoring the urgent need for continued awareness, prevention, and innovation5.
As the first cancer to be successfully treated with immunotherapy, melanoma has seen major improvements in patient outcomes over the past decade. These advances, including the introduction of immunotherapy and targeted therapies, have dramatically improved survival rates for patients with advanced melanoma. Before the availability of these treatments, only a small percentage of patients survived three years after diagnosis. Today, the 10-year survival rate has risen significantly, offering new hope where previously there was little6.

The role of immunotherapy and the need for continued innovation
Immunotherapy, a revolutionary approach to cancer treatment, is a key driver of this progress. Unlike chemotherapy, which directly targets cancer cells, immunotherapy activates the body's immune system. Our immune system is naturally equipped to defend against harmful intruders, such as bacteria, viruses, and cancer cells. Immunotherapy boosts or reprograms this system to more effectively recognize and destroy cancer cells, making it a powerful weapon in the fight against cancer.
One particularly promising area of immunotherapy is CAR T-cell therapy, which involves reprogramming a patient's own T cells to target cancer cells more effectively. To support the development and accessibility of such personalized treatments, we have started building a brand new CAR T-cell therapy production facility in Leiden, the Netherlands — bringing these innovative medicines closer to European patients.
Our initiatives for patients and healthcare professionals
At Bristol Myers Squibb, we are committed to supporting patients and advancing cancer care through various initiatives.

ImmunoScience Academy
All throughout the year, we provide healthcare professionals with up-to-date information and education on immuno-oncology through initiatives such as the ImmunoScience Academy.
This platform brings together immunoscience experts from various therapeutic disciplines to develop and offer educational resources focused on immunoscience, while fostering the exchange of knowledge and experience in this field.

Immuno-Oncology platform
We also provide trusted information and educational support to oncology nurses and patients through our Immuno-Oncology platform, helping ensure optimal care for patients undergoing immunotherapy.
This program was developed in close collaboration with Belgian nurses from various hospital centers and departments, ensuring its relevance and practical application.

Country to Country for Cancer (C2C4C)
In addition to our educational efforts, BMS employees from Belgium and the Netherlands participate annually in the Country 2 Country 4 Cancer (C2C4C) cycle tour. This charity event aims to raise awareness and funds for cancer research, supporting European cancer organizations that are part of the C2C4C network.
Together, BMS employees cycle across different countries to contribute to the fight against cancer.
Our medicines in oncology
Our mission is to discover, develop and deliver innovative medicines to patients with serious diseases.
