Vähitüüpe

Vähitüüpe refers to the different classifications of cancer based on the type of cell from which they originate. This categorization is crucial for understanding cancer's behavior, guiding diagnosis, and determining the most effective treatment strategies.

The primary categories of vähitüüpe are carcinomas, sarcomas, leukemias, lymphomas, and central nervous system cancers. Carcinomas arise from epithelial cells, which line the surfaces of the body and organs. This group includes common cancers like breast, lung, prostate, and colon cancer. Sarcomas, on the other hand, develop in connective tissues such as bone, cartilage, fat, muscle, and blood vessels. Examples include osteosarcoma and liposarcoma.

Leukemias are cancers of the blood-forming tissues, typically the bone marrow, leading to an overproduction of abnormal white blood cells. Lymphomas originate in lymphocytes, a type of white blood cell found in the lymphatic system. Central nervous system cancers affect the brain and spinal cord.

Further subtyping within these broad categories is based on the specific cell type and its microscopic appearance. For instance, lung cancer can be classified as small cell lung carcinoma or non-small cell lung carcinoma, with the latter further divided into adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. This detailed classification allows for more precise prognoses and tailored therapeutic approaches. Understanding these vähitüüpe is fundamental to the ongoing fight against cancer.
