It is more likely that a cauliflower-shaped mass is cancer, which is above 90%, but there is no way to determine how much it is, and we must rely on biopsy pathology. Other benign lesions, such as proliferative inflammation, may also appear similar to cauliflower-like changes, so the diagnosis of cancer cannot be fully confirmed by cauliflower-like appearance. Cauliflower-shaped masses of cancer may be brittle and bleed easily during biopsy, and postoperative pathology is also the basis for diagnosis. If it is inflammatory, the biopsy pathology may suggest benign lesion, which requires surgery with anti-inflammatory treatment. In addition to cauliflower-shaped cancer, there are also indurated ulcers, which are malignant ulcerative lesions, such as gastric and colonic ulcers, etc. Biopsy pathology can also confirm the diagnosis of cancer.
