Bladder Cancer
Overview
Bladder cancer arises from the cells lining the bladder and is strongly linked to smoking. It often first presents as painless blood in the urine, which is why any episode of visible blood — even a single one — always needs evaluation.
Symptoms
Causes
Smoking is the single leading risk factor. Occupational exposure to certain industrial chemicals and dyes, along with chronic bladder irritation, also contribute.
Risk Factors
Diagnosis
Diagnosis involves urine cytology, cystoscopy with biopsy to directly visualize and sample any tumor, and imaging to determine the extent of disease.
Complications If Untreated
Untreated bladder cancer can invade surrounding tissue and spread to other organs; even after treatment, ongoing surveillance is needed given the recurrence risk.
Treatment Options
Prevention Tips
Not smoking is by far the single most protective step; protective equipment reduces risk for those in higher-exposure occupations.
Lifestyle Advice
Never dismiss even a single painless episode of blood in the urine — it should always be evaluated promptly.
