text: Yo, check it out, I got a study to share,
  Investigatin' tumors, it's a scientific affair.
  They took 50 male rats, induced tumors in their bladder,
  N-butyl-N-(4-hydroxybutyl)-nitrosoamine, makin' it matter.
  
  They wanted to see if there's a correlation,
  Between tumor pathology and hematuria's formation.
  Macro- and microhematuria, they wanted to explore,
  Using Azopiram, their agent, to monitor for sure.
  
  They found microhematuria, at the very start,
  When neoplastic changes were playin' their part.
  Focal hyperplasia and micropapillomatosis,
  Early signs of trouble, causin' a commotion.
  
  As the tumors matured, things got intense,
  Microhematuria transformed, it made no pretense.
  It turned into macrohematuria, a sight to behold,
  Malignancy takin' hold, the story unfold.
  
  They say this test could be a self-control tool,
  For recurrent bladder cancer, a powerful tool.
  Outside the clinic, it could bring some relief,
  Keepin' tabs on your health, a sense of belief.
  
  So there you have it, the study is done,
  Tumor pathology and hematuria, they've won.
  With Azopiram as their watchful guide,
  They've uncovered insights, taken it in stride.
