Tumorsejtekben refers to cells within a tumor. These cells are characterized by uncontrolled proliferation and the potential to invade surrounding tissues or metastasize to distant sites. Tumorigenesis, the process by which normal cells transform into tumor cells, involves genetic mutations and epigenetic alterations that disrupt normal cellular regulation.

The study of tumor cells is crucial for understanding cancer biology and developing effective therapeutic strategies. Tumor cells exhibit a range of abnormal properties, including altered metabolism, resistance to apoptosis (programmed cell death), and the ability to induce angiogenesis (the formation of new blood vessels) to support tumor growth.

Different types of cancer are characterized by distinct tumor cell populations with varying genetic profiles and biological behaviors. For instance, solid tumors are composed of a heterogeneous mix of cancer cells, stromal cells, immune cells, and blood vessels. The microenvironment surrounding tumor cells also plays a significant role in tumor progression and response to treatment.

Research into tumor cells encompasses their genetic and molecular characteristics, their interactions with the immune system, and their behavior in response to various treatments. This knowledge is fundamental for the diagnosis, prognosis, and management of cancer.
