vähitüübi

Vähitüübi refers to a category or classification of cancer. In medical science, cancers are not all the same; they differ significantly in their origin, growth patterns, microscopic appearance, and response to treatment. Classifying cancer into specific types is crucial for diagnosis, prognosis, and determining the most effective therapeutic strategies.

The primary classification of cancer is based on the type of cell from which it originates. Carcinomas arise from epithelial cells, which form the skin and the lining of organs. Sarcomas develop from connective tissues like bone, muscle, cartilage, fat, or blood vessels. Leukemias are cancers of the blood-forming tissues, typically the bone marrow, leading to the production of large numbers of abnormal white blood cells. Lymphomas originate in the lymphatic system, which is part of the immune system. Myelomas are cancers of plasma cells, a type of immune cell found in the bone marrow.

Further sub-classifications exist within these broad categories. For instance, carcinomas can be further divided into adenocarcinomas (glandular epithelial cells) and squamous cell carcinomas (flat, scale-like epithelial cells). The specific vähitüübi dictates the characteristic behavior of the cancer, such as its likelihood to metastasize (spread to other parts of the body) and its sensitivity to chemotherapy, radiation therapy, or targeted drug treatments. Understanding the precise vähitüübi is therefore fundamental to personalized cancer care.
