Final answer:
The International Classification of Diseases (ICD) is the correct system for classifying neoplasm topography and morphology, which includes cancer staging categories based on tumor size and cancer spread to determine prognosis and treatment.
Step-by-step explanation:
The International Classification of Diseases (ICD) is a system for classifying the topography and morphology of neoplasm. This classification, maintained by the World Health Organization (WHO), is utilized in clinical fields to classify diseases and to monitor morbidity and mortality. Cancer staging is an important part of the ICD, involving the classification of cancer based on factors such as tumor size and the extent to which the cancer has spread.
The ICD is used to create a standardized language for reporting and monitoring diseases, which is essential for epidemiology, health management, and clinical purposes. Classifications of Disease, such as cancer staging, help in determining the prognosis and appropriate treatment for patients with cancer. Cancer staging includes stages such as 'in situ,' where abnormal cells are present but have not spread to nearby tissue.
