Neoplastic cells can be classified based on their tissue of origin, behavior, and histological characteristics:
1. Carcinomas: Malignant tumors arising from epithelial cells. 2. Sarcomas: Malignant tumors originating from mesenchymal tissues such as bone, muscle, or fat. 3. Leukemias and Lymphomas: Malignancies of hematopoietic and lymphoid tissues. 4. Benign Neoplasms: Non-cancerous growths that typically do not invade or metastasize.
