Bladder cancer forms in which tissue?

Bladder cancer forms in which tissue?

• A. Liver cancer.
• B. Kidney cancer.
• C. Cancer that forms in the bladder tissues.
• D. Adrenal cancer.

Answer: (C)

Bladder cancer forms in the bladder’s own tissues—the mucosal lining of the urinary bladder, which is made up of urothelial (transitional) epithelium. This is where malignant transformation typically occurs, producing urothelial carcinoma, the most common type of bladder cancer. The other organs mentioned—liver, kidney, and adrenal gland—each have their own distinct tissues, and cancers arising there originate in those organs (liver tissue, kidney parenchyma, and adrenal gland tissue), not in the bladder lining.
