Stage III is divided into stages IIIA and IIIB. In stage IIIA, the tumor is larger than 5 centimeters but not larger than 10 centimeters and is mid grade or high grade. Mid-grade and high-grade cancer cells look more abnormal under a microscope and grow and spread more quickly than low-grade cancer cells. In stage IIIB, the tumor is (1) larger than 10 centimeters and is mid grade or high grade; or (2) any size, any grade, and has spread to nearby lymph nodes.
