What are Histological Grading and Staging of Cancer?
Histological grading refers to the assessment of how much the cancer cells differ from normal cells. It often predicts the aggressiveness of the cancer. Low-grade cancers look more like normal tissue and tend to grow slower, while high-grade cancers look very different and grow more rapidly.
Staging, on the other hand, describes the extent of cancer spread within the body. It involves evaluating the size of the tumor, involvement of lymph nodes, and presence of metastasis. The TNM system (Tumor, Node, Metastasis) is commonly used for this purpose.
