*Bilharzial-associated SCC (BSCC) - not associated with bilharziasis (Schistosoma). | |||
*Non-bilharzial SCC (NBSCC). | |||
Characteristics of NBSCC:<ref name=pmid27547458> | |||
*Prevalance ~2-5% of bladder tumours (in Western countries).<ref>URL: [https://www.myvmc.com/diseases/bladder-cancer-squamous-cell-carcinoma-of-the-bladder/ https://www.myvmc.com/diseases/bladder-cancer-squamous-cell-carcinoma-of-the-bladder/]. Accessed on: 14 February 2018.</ref> | |||
*Usually high-grade. | |||
*Typical patient 7th decade. | |||
**Fifth decade for BSCC | |||
*Present with hemature without irritative bladder symptoms. | |||
*Risk factors: indwelling catheters, chronic inflammation/irritants. | |||
