Tumor (T)

Tumor (T) refers to the size and extent of a primary tumor in cancer staging. It measures how large the tumor is and whether it has grown into nearby tissues. A higher T number indicates a larger or more invasive tumor, while a lower number signifies a smaller, less invasive one. This classification helps doctors determine how advanced the cancer is, guide treatment options, and predict outcomes. Essentially, T helps describe the local extent of the cancer at the original site.
