The bulging type of colon cancer is not the giant type. The general types of colon cancer include ulcerative type, bulging type and infiltrating type. Bulging type is the general classification of colon cancer, in which the main body of tumor protrudes into the intestinal lumen, ulcers can be produced on the surface of the mass when it is enlarged, and there is little infiltration into the surrounding, so the prognosis is better. Hepatocellular carcinoma is categorized into nodular type, massive type and diffuse type. And bulky type is the general pathological classification of hepatocellular carcinoma, in which the tumor is single, multiple or fused into a mass with a diameter larger than 10cm. So bulging colon cancer is not giant mass type.
