Non-invasive bladder cancer: what to know

Bladder cancer starts in the bladder lining in many cases. Non-invasive disease has not grown into the bladder muscle on the information available from assessment. Doctors use the tumour's appearance, grade, number and depth to estimate how it may behave and to plan care. [Cystoscopy](/treatments/diagnostics-and-staging/cystoscopy/) lets a clinician inspect the bladder and may allow removal or sampling of an abnormal area.

Blood in the urine, changes in urinary frequency, burning or [Difficulty Passing Urine](/symptoms/difficulty-passing-urine/) can occur for several reasons. These symptoms need assessment rather than an assumption about cancer.

Treatment often begins with removing visible tumour through a scope. Depending on the risk features, the team may recommend medicine placed directly into the bladder, such as [Intravesical BCG Therapy](/treatments/systemic-therapy/intravesical-bcg-therapy/), or another local treatment. Selected situations may involve [Chemotherapy](/treatments/systemic-therapy/chemotherapy/) or [Immunotherapy](/treatments/systemic-therapy/immunotherapy/). [Bladder Removal Surgery](/treatments/surgical-oncology/cystectomy/) is considered for particular high-risk or recurrent patterns, not simply because a tumour was found. Keep every planned cystoscopy and report new urinary symptoms between visits.

Contact your care team promptly for heavy or persistent blood in the urine, clots, fever, chills, worsening pain or difficulty passing urine. Seek emergency care if you cannot pass urine, feel faint, have severe abdominal or back pain, or are seriously unwell. After a bladder procedure, follow the discharge instructions about fluids, activity and warning signs, and ask where to call outside office hours.

Ask: What grade and stage is the tumour? Was it completely removed? Has it reached the muscle? Do I need treatment inside the bladder? How often will cystoscopy be needed? Which urinary changes are urgent? If the cancer returns, what would the next option be?
