Cancer is a disease of abnormal gene function. This means genetic changes like mutations, chromosomal breakages, duplication, and so forth can trigger cancer development. Studies show that patients with the same type of cancer can have very different outcomes, even with the same treatment. So, cancer treatment should be personalized according to the genetic and molecular features of the cancer in that particular patient. Personalized therapy is the new concept in cancer therapy which is tailored to abnormal genes in the particular tumor, and performed at Anadolu Medical Center.
