Both benign and malignant (cancerous) tumors form on the walls and inside the vesical bladder. Among the first, and most often in urological practice are the following:
• polyps: these are relatively small, smooth neoplasms with a thin stem
• papillomas: these are formations with a pronounced rough surface. Their main danger lies in the risk of malignant degeneration. They are both single and multiple.
Much less often, other benign tumors, including fibroids, fibromas, or hemangiomas, form in this organ.
Malignant neoplasms of the bladder are divided into three types, namely adenocarcinoma, squamous cell, or transitional cell carcinoma, which is the typical type of oncology.
