Tumour Staging

📖What is Tumour Staging?

Tumour staging is the systematic clinical process used by physicians to determine the extent to which a cancer has grown and spread within the body, guiding both prognosis and treatment planning. It typically follows the TNM system, which separately evaluates the size of the primary tumour, whether nearby lymph nodes are involved, and whether the cancer has spread to distant organs through metastasis. Staging relies heavily on imaging studies such as CT, MRI, and PET scans, together with biopsy results and sometimes surgical exploration, to build an accurate picture of disease extent. Accurate staging is essential because it directly determines which treatment approach, ranging from surgery alone to combined chemotherapy, radiation, and systemic therapy, offers the best chance of a successful outcome.
