Precision medicine is the practice of tailoring medical care to the individual based on their unique genetic, molecular, and biological profile rather than applying the same treatment approach to everyone with the same diagnosis. In cancer care, this shift has fundamentally changed what is possible.
Traditional oncology has long relied on a one-size-fits-all model, where patients with the same type of cancer often receive similar treatment regimens despite major biological differences between tumors. Precision medicine challenges that approach directly. By analyzing the specific genetic mutations and molecular characteristics of a tumor, clinicians can identify therapies more likely to benefit a particular patient, avoid treatments less likely to work, and match individuals to clinical trials designed around their cancer’s biology.
This approach, often called precision oncology, helps doctors make more informed treatment decisions using genomic and molecular data. It is now considered standard of care for several major cancer types, including lung, breast, colorectal, and ovarian cancer. In many cases, molecular profiling can help improve outcomes while reducing side effects associated with less targeted treatments.
Precision medicine also extends beyond treatment selection. It can influence diagnosis accuracy, recurrence monitoring, clinical trial eligibility, and long-term care planning throughout the cancer journey.
The articles in this section explore how precision medicine works, the role of genomic and molecular profiling in cancer care, and why many patients still face barriers accessing these technologies despite growing clinical evidence supporting their use.
