vähirakkudel

Vähirakkudel refers to cancerous cells in Estonian. These are cells that have undergone uncontrolled division and growth, losing their normal function and potentially invading surrounding tissues or spreading to distant parts of the body.

The development of vähirakkudel typically begins with genetic mutations that disrupt the cell cycle. These mutations can be caused by various factors, including exposure to carcinogens, viral infections, or inherited predispositions. Once these mutations accumulate, cells can evade normal growth-regulating mechanisms, leading to their abnormal proliferation.

Unlike normal cells, vähirakkudel often exhibit several distinct characteristics. They may grow rapidly, form tumors, and are resistant to programmed cell death (apoptosis). They can also promote the formation of new blood vessels (angiogenesis) to support their growth and invasion into other tissues (metastasis).

Diagnosis of vähirakkudel involves various medical procedures, including imaging techniques, biopsies, and laboratory tests. Treatment strategies for cancer are diverse and depend on the type and stage of the disease. Common treatments include surgery to remove tumors, chemotherapy, radiation therapy, and targeted therapies that specifically attack cancerous cells. Research continues to advance our understanding of vähirakkudel and develop more effective treatments.
