Bladder CancerTreatment for bladder cancer depends on the stage of the disease, the grade of the tumor, and the type of bladder cancer. Options for treatment include surgery, radiation therapy, chemotherapy, and biological therapy.
Bladder SpasmsPeople who have bladder spasms, the sensation occurs suddenly and often severely. A spasm itself is the sudden, involuntary squeezing of a muscle. A bladder spasm, or "detrusor contraction," occurs when the bladder muscle squeezes suddenly without warning, causing an urgent need to release urine. The spasm can force urine from the bladder, causing leakage. When this happens, the condition is called urge incontinence or overactive bladder.
