What is the Importance of Tumor Grading and Staging?
Histological grading and staging of primary tumors are crucial for determining the prognosis and guiding treatment strategies.
- Grading: Assesses the degree of cellular differentiation and mitotic activity. Higher-grade tumors are more aggressive and less differentiated. - Staging: Evaluates the extent of tumor spread within the body. The TNM system (Tumor size, Node involvement, Metastasis) is commonly used.
