According to the International Agency for Research on Cancer, approximately one in five people will develop cancer during their lifetime. With over 100 different types of cancer, each with potentially numerous subtypes characterized by distinct underlying biology and prognoses, treatment options are highly personalized. These options can include surgery, radiotherapy, drug treatment (including chemotherapy and targeted therapies), or active surveillance. Oncologists consider the patient's health, clinical evidence, and treatment goals before deciding on the best course of action. Consequently, two patients with the same type of cancer may receive very different treatments.

Figure one illustrates the crude global treatment rate for the 23 most common cancer types. This rate is defined as the average number of patients receiving drug treatment at any time in 2022, divided by the estimated prevalence of the disease. Both patient counting measures can be found in IQVIA's Oncology Link. It's important to note that patients not on drug treatment may be receiving other forms of treatment or may have no detectable cancer but are not yet considered "cured".
