Cigarette smoking is a significant risk factor for which cancer mentioned in the material?

• A. Renal pelvis cancer
• B. Bladder cancer
• C. Ureteral cancer
• D. Renal cell carcinoma

Answer: (B)

Cigarette smoking introduces carcinogens that are processed and excreted in urine, so the bladder lining is exposed to high concentrations of these toxins for extended periods. This direct exposure to urothelial cells leads to DNA damage and mutations, driving cancer development in the bladder. The risk grows with how long and how much someone has smoked, and it declines after quitting, which strengthens the link between smoking and bladder cancer. Among the options, this cancer has the strongest and most consistent association with smoking, making it the best answer. While cancers of the renal pelvis and ureter can also be related to smoking due to urothelial exposure, the link is strongest with bladder cancer; renal cell carcinoma has a weaker association.
