Oncology. #Precision Medicine and Targeted Therapy in cancer treatment
Precision medicine is treatment which is tailored to the genetic characteristics of the tumour.
Traditionally, cancer has been classified depending on its anatomical location and treatment has been established depending on the affected organ: lung, breast, colon, skin, blood, etc. A person diagnosed with cancer would therefore usually receive the same treatment as other people with the same type and stage of cancer. Even so, individuals could respond differently and until recently doctors did not understand why. After decades of research, scientists now know that patients’ tumours have genetic changes which cause the cancer to grow and spread. They have also learned that changes which occur in cancer in one person may not occur in others with the same type.
