What is the Origin of Molecular Oncology?

The discipline emerged with the advent of molecular biology techniques that allowed for the detailed analysis of DNA, RNA, and proteins within cancer cells, moving beyond purely histological diagnosis. Its origin is marked by the shift from generalized chemotherapy to personalized treatment based on the tumor's unique molecular signature. In hormonal health, it specifically addresses hormone-sensitive cancers like breast and prostate cancer.

What is the Mechanism of Molecular Oncology?

The mechanistic core of molecular oncology involves characterizing oncogenes, tumor suppressor genes, and the intricate signaling networks that control cell growth and apoptosis. For endocrine-related cancers, the focus is on pathways like the estrogen receptor (ER) and androgen receptor (AR) signaling, which, when hyperactivated, promote tumor proliferation. Targeted therapies, such as selective receptor modulators, function by precisely disrupting these aberrant molecular communication pathways.

Molecular Oncology

Meaning

Molecular Oncology is a specialized branch of medicine and biology that investigates the fundamental molecular and cellular mechanisms underlying the development, progression, and metastasis of cancer. This field focuses on identifying specific genetic mutations, protein dysfunctions, and aberrant signaling pathways, including those influenced by hormones, that drive malignant transformation. This molecular-level understanding is essential for developing highly targeted, precision therapeutic agents.
