Answer

The presentation in bladder cancer may resemble a urinary tract infection (UTI), or the 2 conditions may coexist. Both UTIs and bladder cancer can cause hematuria, and bacteriuria occurs in about 50% of patients with squamous cell carcinoma (SCC). Patients with bladder cancer may have spontaneous resolution of gross or microscopic hematuria, which may lull the patient and the clinician into erroneously believing that no significant entity is present. UTIs are usually associated with irritative voiding symptoms (eg, dysuria, frequency, urgency). However, around 80% of patients who have carcinoma in situ (CIS) will also present with irritative voiding symptoms.  [64]
