Introduction
Molecular oncology, at its core, is the scientific discipline that investigates the molecular underpinnings of cancer. This field has emerged as a cornerstone of cancer research, revolutionizing our understanding of the disease and its treatment. It delves into the intricate genetic and molecular alterations that drive cancer initiation, progression, and response to therapy. The significance of molecular oncology lies in its ability to uncover the molecular mechanisms responsible for the complex behavior of cancer cells, ultimately leading to more precise diagnostics, targeted therapies, and improved patient outcomes.
History
The history of molecular oncology is intertwined with the broader history of cancer research. Throughout the ages, cancer has been a formidable foe, and its mysteries have captivated scientists for centuries. However, it wasn t until the mid-20th century that the molecular aspects of cancer began to be unveiled. Breakthroughs in understanding the genetic basis of cancer included the identification of oncogenes—genes with the potential to drive cancerous transformation—and tumor suppressor genes—genes that normally keep cell growth in check. The discovery of the Ras oncogene in the 1980s marked a pivotal moment in understanding the genetic basis of cancer, highlighting the importance of molecular alterations in cancer development.
