Ráktípusok

Ráktípusok refers to the various classifications of cancer. Cancers are primarily categorized based on the type of cell they originate from and the tissue where they first appear.

Carcinomas are the most common type of cancer, originating in epithelial cells, which form the skin and the lining of internal organs. Examples include lung cancer, breast cancer, and prostate cancer. Sarcomas arise from connective tissues like bone, cartilage, muscle, and fat. Lymphomas develop in the immune system's lymphocytes, and leukemias are cancers of blood-forming tissues, typically in the bone marrow. Myelomas are cancers of plasma cells, a type of white blood cell.

Further classifications exist within these broad categories, often detailing the specific cell type (e.g., adenocarcinoma, squamous cell carcinoma) and the location of the primary tumor. Understanding the ráktípusok is crucial for diagnosis, treatment planning, and research, as different cancer types behave differently and respond to various therapies. The World Health Organization's International Classification of Diseases (ICD) is a standard system used globally for coding and classifying diseases, including different ráktípusok. Genetic and molecular profiling also plays an increasingly important role in refining these classifications and identifying targeted treatment options.
