    Smoking is a significant risk factor for bladder cancer, increasing the risk by 2-to-4 times compared to non-smokers.

  • 2

    BLCA-4 expression was significantly elevated in bladder cancer patients, both smokers and non-smokers, compared to healthy controls.

  • 3

    Low-grade tumors were found in non-smoking bladder cancer patients, while high-grade tumors were identified in smoking patients.

  • 4

    Changes in specific STR loci were observed in urine samples from bladder cancer patients, indicating genetic instability.

  • 5

    Urine samples can effectively be used for diagnosing bladder cancer through BLCA-4 assessment and STR genotyping.
