Tumorbiológia

Tumorbiológia, also known as cancer biology, is the scientific study of cancer. It investigates the biological basis of cancer development, progression, and response to treatment. This field seeks to understand the genetic and molecular alterations that lead to uncontrolled cell growth and the formation of tumors. Tumorbiológia explores the cellular mechanisms involved in tumor initiation, including mutations in DNA, activation of oncogenes, and inactivation of tumor suppressor genes.

A key area of focus is the tumor microenvironment, which encompasses the cells, blood vessels, and extracellular matrix surrounding the tumor. This microenvironment plays a crucial role in tumor growth, invasion, and metastasis. Tumorbiológia also examines the complex interactions between cancer cells and the immune system, leading to fields like immuno-oncology.

The ultimate goal of tumorbiológia is to translate this knowledge into improved diagnostic tools, more effective therapies, and ultimately, prevention strategies for cancer. By understanding the fundamental biological processes driving cancer, researchers aim to develop targeted treatments that specifically attack cancer cells while minimizing damage to healthy tissues. This includes the study of drug resistance mechanisms and the development of novel therapeutic approaches.
