Among the 10 studies you to definitely reviewed bladder disease prices from the sex and you can was in fact within the 2012 microscopic hematuria recommendations, half a dozen studies receive no instances of bladder malignant tumors one of lady people. The speed out-of women bladder cancer tumors all over these studies is 0–0.3% PubMed]”>07 PubMed]”>08 PubMed]”>09 PubMed]”>ten PubMed]”>eleven PubMed]”>12 PubMed]”>thirteen PubMed] [Full Text]”>14 PubMed]”>15 PubMed] [Full Text]”>16.
