The Role of Molecular Biology in Cancer Treatment: Advances, Applications, and Future Perspectives

الملخص

Cancer is a genetic disorder primarily caused by several mechanisms, including the activation of oncogenes, the breakdown of tumor suppressor genes, or mutagenesis resulting from external influences. During the latter part of the 20th century, our understanding of cancer biology has advanced remarkably. Currently, we comprehend cancer at the genetic and epigenomic levels, having identified the cell initiating neoplastic transformation and outlined the processes behind tissue invasion. The advancement of diagnostic instruments and therapies through a molecular biological framework enables the implementation of sensitive, noninvasive testing for cancer patients. This knowledge has allowed novel drugs to be designed that act on specific molecular targets, the immune system to be trained and manipulated to increase its efficiency, and ever more effective therapeutic strategies to be developed. The accurate diagnosis, prognosis, and prediction of cancer patients' responses to treatment are crucial for optimizing therapy, minimizing adverse effects, and targeting interventions. In this regard, molecular biology has gained significant prominence in oncology. However, we remain distant from achieving victory in the battle against cancer; hence, biomedical research in oncology must persist as a worldwide imperative.
