title: A clinicoepidemiological study of young age bladder tumors: An eastern Indian scenario.
abstract: BACKGROUND
  Though, bladder cancer is one of the most common urological malignancies, studies addressing the young age group bladder tumors are rare. Present study was done to determine the clinicoepidemiological aspects of bladder tumor diagnosed in young age patients and to compare these aspects with elderly patients.
  
  
  METHODS
  Patients with urinary bladder tumor were selectively divided into two groups; young (<40 years) and elderly (>60 years). Groups were compared on various parameters and statistically analyzed using Fisher's exact two-tailed test.
  
  
  RESULTS
  Smoking, tea and coffee intake and exposure of dye were found significantly associated with development of bladder tumor. Most of the tumors in young age were small, solitary, and papillomatous. Transitional cell carcinoma (TCC) was the most common histological subtype, though most were of low grade and were non-muscle invasive in comparison to the tumors in elderly group.
  
  
  CONCLUSIONS
  The incidence of bladder cancer is common in younger age group. Active and passive cigarette smoking, tea, coffee intake, and exposure to organic dyes are major risk factor for younger age group bladder tumor in this part of world. TCC is most common histological subtype and most of them are in low grade without muscle invasion.
