text: Bladder cancer, yo, it's the tenth most frequent
  In the world, check it out, let me speak it
  To diagnose and surveil, we need a combo
  Invasive and non-invasive methods, yo, it's a costly show
  
  Cystoscopy with urine cytology
  Histological examination, that's the standard policy
  We study biomarkers, proteins, genes, and RNAs
  In relation to BC, we turn the page
  
  But yo, liquid biopsy, it's a new trend
  Proving to be effective, almost equally, my friend
  Cell-free DNA, non-coding RNA
  Subcellular structures, we test 'em all day
  
  In this review, we focused on gene mutations
  DNA fragments, epigenetic modifications, no confusion
  Liquid biopsy, acquiring non-coding RNA
  PubMed, Scopus, Web of Science, we roam
  
  "Bladder cancer" and "markers" or "biomarkers" we seek
  Published until August 2022, knowledge we leak
  80% sensitivity and specificity, the threshold set
  Precision medicine, yo, it's the bet
  
  Complex lab techniques, they fuel the search
  For sensitive and specific biomarkers, it's the birch
  Diagnosis, follow-up, and screening, we strive
  In everyday clinical practice, their utility will thrive
