Bladder cancer is a malignancy that originates in the tissues of the bladder, a hollow organ responsible for storing urine. The most common type of bladder cancer is urothelial carcinoma, which begins in the cells lining the bladder. This cancer often presents with symptoms such as blood in the urine, frequent urination, and pain during urination. Understanding bladder cancer involves recognizing its diverse types, risk factors, and associated signs, enabling individuals to seek timely medical attention for accurate diagnosis and appropriate treatment.
