KARACHI: While smoking is globally notorious for causing lung cancer, health experts have issued a stark warning that it also drastically increases the risk of developing bladder cancer by up to four times. Nephrologists and medical specialists emphasize that blood in the urine is often the primary and most critical early symptom of this life-threatening disease.
According to medical experts, public awareness heavily links tobacco use to lung diseases, yet its severe impact on the urinary tract remains largely overlooked.
Highlighting the gravity of the issue, noted Indian specialist Dr. Ankur Bhatnagar stated that individuals who smoke face a two-to-four times higher risk of bladder cancer compared to non-smokers. This staggering statistic positions tobacco consumption as the single most significant risk factor for the disease.
How Smoking Targets the Bladder
Explaining the biological mechanism, Dr. Bhatnagar revealed that the danger lies in how the body processes tobacco smoke. Carcinogens (cancer-causing chemicals) present in cigarette smoke enter the body through the lungs and are absorbed directly into the bloodstream. The kidneys then filter these toxic chemicals out of the blood and direct them into the urine. As the bladder stores this urine before excretion, these harmful carcinogens remain in prolonged, direct contact with the bladder’s inner lining. Over time, this continuous exposure triggers cancerous cellular mutations, ultimately leading to the onset of bladder cancer.
Health professionals are urging citizens to recognize early signs like blood in the urine and to adopt tobacco-free lifestyles to mitigate these severe health risks.
